Mobile Developer career guide

What a Mobile Developer does

A Mobile Developer builds and maintains apps for phones and tablets. They may work on apps for one platform, such as iOS or Android, or build cross-platform apps that run on both.

Typical work includes:

• Turning product requirements and designs into working features
• Writing, testing, and fixing code
• Connecting apps to websites, databases, and other services
• Improving performance, accessibility, and security
• Updating apps as operating systems and user needs change
• Working with designers, product teams, testers, and other developers

A typical day

A typical day might include reviewing tasks with a team, writing code for a feature, testing it on a device or simulator, and fixing bugs. You may also review a teammate’s code, discuss a design decision, or investigate a problem reported by users.

The balance of coding, meetings, and testing depends on the team and the stage of the app.

Skills you need

• Programming: Learn a language and tools used for your chosen platform. For example, iOS development commonly uses Swift, while Android development commonly uses Kotlin.
• Mobile development concepts: Understand screens, navigation, app lifecycle, notifications, and how apps handle limited connectivity.
• Problem-solving: Break features into smaller tasks and find the cause of errors.
• Testing and debugging: Check that an app works across relevant devices and conditions.
• User-focused thinking: Consider usability, accessibility, and how people interact with apps.
• Communication and teamwork: Explain technical choices and collaborate with people in different roles.
• Ongoing learning: Mobile platforms and development tools change, so keeping your skills current matters.

How to become one

• Education: A degree in computer science or a related subject can provide a foundation in programming and software design. It is not the only route; practical skills and a strong portfolio can also help.
• Certifications: Some platform or training providers offer courses and certificates. They can help structure your learning, but they are usually most useful when paired with projects that demonstrate what you can build.
• Self-study: Choose a platform, learn its language and development tools, and build small apps. Gradually take on projects involving data storage, network requests, and testing.
• Entry routes: Look for internships, apprenticeships, junior developer roles, or adjacent software roles where you can gain relevant experience. Personal projects, contributions to shared projects, and freelance work may also help demonstrate your abilities.
• Build a portfolio: Include a few finished projects, explain what you built and why, and make your code or demonstrations easy to review.

Career path

A common progression is from junior developer to mid-level developer, then to senior developer. With experience, you might move into a specialist role, lead a development team, or shift toward software architecture, product development, or engineering management.

Progression varies by workplace. Developers can also deepen their expertise in a platform, accessibility, performance, security, or cross-platform development without moving into management.

Is it right for you?

Mobile development may suit you if you enjoy solving problems, building things people use directly, and learning new tools. It can be rewarding to see a feature take shape on a device.

Consider whether you are comfortable with careful testing and frequent changes to platforms and requirements. If you enjoy both technical work and thinking about the user experience, it may be a good fit.
