Summary: In this article, we will discuss the dynamics of a mobile app development team, explaining various functional positions within it, structure, roles and responsibilities, and more. By the end of the read, you’ll have specific tips and insights into how to build an ideal team. Read ahead.
A significant issue that current and aspiring business owners continue to face is the constantly shifting mobile technology environment. As the bar is set higher in terms of user satisfaction, it’s imperative to provide a valuable and unique mobile app. But this is also a point of challenge in this saturated market, especially when there are already over 5.7 million apps in the Play Store and App Store.
To address this, perhaps the best move is to have a competent mobile app development team with multiple specialists. Having specialized team members with clearly defined roles and responsibilities, including project managers, UI/UX designers, developers, and QA testers, ensures that every part of the application is well-developed, and the entire project goes as efficiently as possible.
This approach increases the chance of developing a superior mobile application with optimized performance, usability, and sales.
But how do you find an ideal team to build your app? How many specialists do you need and for what? What’s the best way to hire and manage them? How much will it all cost? - without clear answers, business leaders and decision-makers don’t often know the right approach, which ultimately impacts the development of the end product.
We've put together this piece of content with those exact answers, and a lot more insights. Who are we to answer? A development company that has worked with over 4200 projects and precisely built over 200+ apps. In doing so, we've assembled teams for clients coming from various industries and regions.
While many teams performed exceptionally well, a few in our early days could have been structured better. Those and every other experience have shaped our understanding of what makes a winning mobile app developer team. Here's our take on that.
The team developing a mobile app often has several specialists who address specific tasks to create different parts of the app. Although the team setup can vary according to the project requirements, the following roles form the basic structure:
The project manager acts as the coordinator of the team whose primary goal is to keep the project on track considering the timeline, resources, and scope. They maintain communication and coordination between different team members and all stakeholders to manage tasks, handle risks, and tackle challenges.
PMs are responsible for achieving required product outcomes and keeping workflows as efficient as possible. For that, they must have soft skills like strong communication, leadership, problem-solving, and time management, along with technical knowledge, risk management expertise, and an understanding of agile methodologies.
The product owner is accountable to stakeholders and consumers - the person who takes ownership of the product by aligning it with business and customer needs. They must manage the product backlog and define task priorities according to the client's requirements and assign them to the development team. Their responsibility also includes ensuring that the product adapts to changing business objectives and consumer requirements.
In a mobile app team, business analysts work as a bridge between the development team and the client. The role of a BA revolves around collecting and analyzing requirements and preparing detailed documentation reflecting the overall technical requirements corresponding to the business needs.
They also assist in outlining workflows and processes that the application would support and that the features of the app are aligned to meet the users’ expectations.
These distinctive specialists manage the application's appearance, design, and user experience. A UI/UX designer’s job is to do user research and create intuitive and engaging app interfaces that users find effortless and enjoyable to interact with. They also create wireframes and build well-designed prototypes that simulate the app’s functionality and provide a visual representation of the user flow.
Mobile app developers write the code for iOS and Android app development. They use programming languages like Swift for Apple's iOS operating system and Kotlin or Java for the Android operating system, among others. They're also proficient in using IDEs like Apple's Xcode and Google's Android Studio.
In addition to that, developers need to check whether the app is working correctly, interacts appropriately with the backend services, and complies with the operating system's requirements.
QA engineers are responsible for testing the application to quickly discover all the defects that the app has or may be present in it according to the performance and security standards. They are responsible for designing and implementing testing strategies to deliver a quality application.
Additionally, they help developers solve testing problems, fix errors to enhance the app’s stability before it gets released to the market, and make sure the product is in align with the latest software testing and QA trends.
Once you have your app idea, turning it into a functional and saleable product means you have to invest in multiple skills, resources, and technical support right from the planning phase and throughout the entire development life cycle of the app.
Now the process of app development falls into six significant stages, with the team members and their core responsibilities specified in each stage:
Objective
Business goals are the keystone of the app. Members of the app building team decide about the app's features, competitor analysis, target audience, and unique value proposition at the discovery stage.
Key Roles and Activities
Objective
The primary responsibility of the professionals involved in this phase is to validate the design and concept of the app using a visual model- a prototype.
Key Roles and Activities
Objective
The goal here is to create a detailed user interface according to the mobile app design requirements.
Key Roles and Activities
UI/UX Designer: Creates high-fidelity, visually detailed designs based on the feedback of the prototype, including final layouts, colors, typography, icons, and branding elements.
Product Manager: Works with designers to confirm that the final design meets both business and user requirements.
UX Researcher: Conducts user testing on high-fidelity designs and evaluates the usability of the design based on feedback and analysis.
Front-End Developer: Reviews the high-fidelity design with the team to assess whether all interactive elements are feasible to implement technically.
This is one of the crucial stages of mobile app development. Developers mostly work in this phase as they start coding in sprints and iterate until each and every element of the app is programmed.
Key Roles and Activities
Front-End Developer: Translates UI/UX designs into graphical UIs and interactive mobile screens, integrates APIs for fetching and displaying data.
Backend Developer: Develops server-side code, databases, and APIs integrated into the mobile app.
Project Manager: Coordinates with the development team and ensures the project is progressing according to the roadmap, tracks deliverables as per sprint goals.
Product Manager: Maintains active interaction and guarantees compliance with the determined contract requirements.
DevOps Engineer: Sets up and manages CI/CD pipelines for automated deployments and configures the cloud platform for hosting backend services.
At this stage, the key responsibilities in a mobile app development team include testing the product’s usability, resolving issues, and implementing further updates.
Key Roles and Activities
QA Engineers: Checks and reports bugs to developers, conducts various types of testing, and creates test plans and test cases.
Tester: Performs manual and automatic test scripts to identify unexpected system behavior and evaluate user experience.
Developers: Implements fixes and improvements and works with testers to validate resolved issues.
Project Manager: Coordinates between testers, developers, and stakeholders, tracks bug reports, and checks fixes are implemented.
For the final part, the development team prepares the mobile app for release to the public and allows users to access it.
Project Manager: Develops and executes a deployment plan with timelines and manages risk mitigation strategies in case of issues during launch.
Developer: Prepares app builds for submission to the app store, implements app store optimization (ASO) strategies, and handles any technical issues.
Product Manager: Reviews the final product, coordinates the release schedule with the client, and sets post-launch success metrics.
Choosing the right size for your mobile applications development team is crucial to balancing quality, speed, and cost. Too few specialists, development can drag on, quality may suffer; too many specialists, costs can skyrocket, and the development can become complex.
The appropriate team size depends on the complexity of the app, required features and technology, the desired development cost and timeline, and your available budget. Accordingly, the team can range from 5 to 15 members.
Here's a detailed breakdown:
A smaller team with 5-8 members can handle basic apps or MVPs. In such projects, the roles of developers, UI/UX designers, and QA engineers might be interchanging.
If your app is more complex with multiple features, you need a separate team for frontend and backend development. There can be one or two people for design and QA, but the product manager plays a larger role.
For large-scale projects with high complexity, a team with multiple developers with different specializations (iOS, Android, backend) is a must, along with a dedicated design team. You might also need a larger product team and multiple QAs.
To optimize your development team size, align your priorities and resources. If your priority is a quick market entry and you have ample funds, consider hiring additional specialists to speed up the development.
Alternatively, if you’re working with a limited budget, you might simplify the app’s functionality, start with a single platform, or hire a leaner team. You must carefully consider the above-mentioned factors to create an efficient development process that meets your project needs.
Identifying the right team and the respective members to build your mobile app is essential. The right team makes your project a success, a wrong one Well, it is time to look at five models for recruiting the right specialists for your business.
In-house developers work under your organization as full-time employees. With them, you have full control over the project and direct access to the team. The in-house model provides total autonomy in team selection, development, and professional growth.
It is suitable for big projects that require extended time to complete, although it is expensive and time-consuming to hire and maintain an in-house team.
It is a remote team of IT professionals not belonging to the client's organization. It comprises dedicated professionals who you have full control over like an in-house team but with the flexibility of outsourcing.
Hiring and managing a dedicated development team is relatively easy to manage and cost-effective, but some of the issues that may affect this model are time zones and possible breaches of confidentiality.
Freelancers work on individual projects. They can be cheap and versatile, thus suited for one-time projects or urgent situations. However, the biggest issues include quality control, confidentiality in the shared space, and where to find the right professional.
In this model, businesses hire certain specialists from a third-party company. These employees become a part of your team and work directly under your supervision, which provides a fast strategy for the work process and saves the money needed to train new employees.
However, IT staff augmentation requires more effort and has concerns regarding security and interaction with clients.
Outsourcing is slightly different from subcontracting (only specific tasks are assigned to external teams,) as it involves allowing a third party to manage the full project on your behalf. This model for mobile app development team structure has the advantage of a ready-made team with an established workflow of their own.
Thus, it is the perfect choice for initiating new projects and rescuing existing ones. It is cheap and efficient but may offer less flexibility in development and face communication challenges.

Before you start looking for a team, you need to think through a few key factors – things you should pay extra attention to if you’re building a dev team for the first time, or you’ve struggled before:
The location of the team influences the cost, communication, talent availability, and even work culture in some way. A development team from Western Europe and North America is drastically more expensive to hire than that of Eastern Europe or Asia. Additionally, a region with time-zone differences might cause communication barriers unlike a local team.
Also, different regions have different strengths. The U.S. has a vast pool of experienced engineers, Eastern Europe is known for strong technical talent, and India excels in offering cost-effective solutions.
The hiring model decides how your team will collaborate, communicate, and manage the project. As we discussed, in-house teams offer full control over the project but at higher costs and long-term commitments. Outsourcing can be cost-effective, but it needs more oversight to manage a mobile app development team. A dedicated team offers full focus on your project, but it can be expensive.
Hence, select the relevant engagement model according to your project's scope, budget, and desired level of involvement.
Full-time, part-time, or hourly rates impact the structure of the app development team. Full-time employees offer stability but come with higher overhead costs. Part-time workers bring flexibility and can be useful for specific tasks but may have limited availability and less engagement. Hourly-rate contractors provide cost-effectiveness but might lack continuity and long-term commitment.
Consider your app's features and requirements upfront to avoid under or over-hiring. Creating a simple with basic features needs a small team of developers and a designer to get things off the ground. But for apps with complex functionalities, you’ll need a larger team with specialized roles.
Moreover, the scope also influences the development timeline. A more extensive project will need a team capable of managing multiple tasks simultaneously, and that will increase the cost.
According to the roles and skill sets of core team members and the size of the team, the hiring cost vary and that impacts of overall cost of a development team.
Here's a breakdown:
Role | Cost/Year (USA) | Cost/Year (Western Europe) | Cost/Year (Eastern Europe) | Cost/Year (India) | Cost/Year (Southeast Asia) |
---|---|---|---|---|---|
Project Manager | $80K-$150K | $70K–$130K | $40K–$80K | $20K–$60K | $15K–$40K |
Product Owner | $90K–$150K | $80K–$140K | $40K–$80K | $25K–$50K | $15K–$40K |
Business Analyst | $80K–$130K | $70K–$120K | $35K–$70K | $12K–$35K | $10K–$30K |
UI/UX Designer | $70K–$120K | $60K–$110K | $35K–$70K | $10K–$30K | $8K–$25K |
App Developers | $80K–$160K | $70K–$140K | $40K–$90K | $12K–$50K | $10K–$40K |
QA Engineer | $60K–$110K | $50K–$100K | $30K–$60K | $8K–$25K | $6K–$20K |
Now check out the estimated annual costs for different team sizes across various regions:
Team Size | USA Cost | Western Europe Cost | Eastern Europe | India Cost | Southeast Asia Cost |
---|---|---|---|---|---|
Small (3–5 people, MVP Development) | $250K–$600K/yr | $120K–$300K/yr | $40K–$120K/yr | $30K- $100K/yr | $15K- $80K/yr |
Medium (6–10 people, Scalable App) | $500K–$1.2M/yr | $250K–$600K/yr | $80K–$250K/yr | $70K-200K/yr | $50K-150K/yr |
Large (10+ people, Complex App) | $1M+/yr | $500K+/yr | $350K+/yr | $250K+/yr | $150K+/yr |
In summary, the cost of creating a mobile app development team depends on location, team size, and roles. In the USA and Western Europe, costs range from $250K–$1M+ per year, whereas in India and Southeast Asia, it's significantly lower at $30K–$250K per year.
Having been through this process countless times, I always sit down with my clients for a chat before we even start the project. I make it a point to hammer home the idea of assembling a group that truly gets your vision and meets your requirements.
In this section, I'll share some practical tips and insights from my own experiences to help you create the best possible mobile app dev team:
1. Go Beyond Technical Skills
Your developers can always learn new skills, but passion for the project and industry is a bonus. Look for people who are genuinely excited about the project. They'll go the extra mile to solve problems creatively and stay invested in the product. The positive spirit a team member brings to the table can positively influence the rest of the team and, of course, the project outcome.
2. Prioritize Cross-Disciplinary Talent
Instead of hiring specialists for each task, think about hiring multidisciplinary team members who have cross-departmental skills. A developer with a good grasp of UI/UX design, or a designer who knows a little bit about coding, can go a long way.
3. Define Clear Ownership Early On
The worst thing that can happen is unclear ownership of tasks. Each team member should have a very clear sense of responsibility from the get-go. It doesn't just help with accountability, but also with decision-making. For example, if a bug comes up, a developer who’s “the person to talk to” about that particular part of the app will avoid confusion and save time.
4. Start Small, Scale Smart
You don't always need a huge team from day one. Begin with core members and then bring in more specialists as the project grows. You will have more flexibility and adaptability in the early stages. Once the app matures, you can scale up by adding more roles to address growing demands.
5. Involve Stakeholders in the Team Process
Get your internal stakeholders involved in the team-building process, even if just for a few key decisions. It gives them a sense of ownership over the team’s success. Plus, their insight into the vision of the product can make the final team assembly much easier.
As a development partner serving global businesses for over 25 years, we help companies that rely on tech solutions for business growth. Radixweb was built on the belief that building an ideal team is the key to delivering successful products, but only when it aligns with the client’s mindset.
This approach has fueled our success and allowed us to deliver bespoke solutions for 3000+ global businesses and grow to a team of 650+ employees. The impact of this strategy speaks for itself in the results we’ve achieved. Check out our success stories to see how.
First up, we take the time to know the client. They share your app idea and business goals, and we show our expertise and past experiences. If both parties agree that Radixweb is the right match for the project, we proceed with technical consultations. This initial discussion leads to our vision for the project, where we outline the best strategy and approach to build your mobile app.
Once we’re on the same page with the client, we decide who’s actually going to build the app. We handpick the best resources based on the project’s needs and share their portfolios for review. Clients can take their time to assess, conduct interviews, and screen candidates to decide on the right fit - no rush, no pressure. Once all team members are finalized, we move on to the next stage.
Next, we assess how the client likes to work. They can choose from our engagement models, or alternatively, we’re here to help. For example, if they prefer tight control, we suggest a hybrid in-house or outsourced model, with key roles handled externally but core development on-site. For more flexible needs, a fully outsourced team with clear milestones may work better.
Once we have the dedicated mobile app team in place, it’s time to define who’s doing what. Each team member knows their role, responsibilities, and what’s expected from them at every stage. We also set clear deliverables and expected TAT throughout the project.
Dedicated communication channels are set up - Skype, Teams, or whatever works best for the client. And project tracking is handled with Redmine or Asana. We also establish a rhythm for check-ins like daily stand-ups, weekly sprint reviews, or bi-weekly deep dives.
With everything in place, we structure the app development life cycle into agile sprints. We prioritize tasks, assign responsibilities, and set achievable outputs for each sprint. The team sets out the first set of development tasks, and coding officially begins!
So, What’s the Takeaway?Just throwing a bunch of skilled people together doesn’t magically create a high-performing app development team. The difference between a good app and a great one is a team that knows how to work together and complement each other. And to build one like that, it takes strategic planning, an eye for detail, and the right mix of skills.You can take the reins and assemble a team on your own, or, if you'd rather, just come to us with your vision and we'll handle the rest.
