Job description

As a Mobile Squad Lead Engineer, you will be the technical backbone of your mobile squad (around 5–7 engineers), leading from the front, writing code daily and setting the standard for high-quality mobile engineering across Android and iOS.

You will work closely with an Engineering Manager to ensure your squad delivers scalable, well-architected mobile applications, while partnering with a Product Manager and UX team to build and ship mobile-first features and experiences.

This is a hands-on role with a strong focus on mobile architecture, coding and problem-solving. You will be the most experienced mobile engineer in the squad, responsible for refining technical requirements, making key platform decisions and mentoring engineers to help them grow.

Using modern mobile technologies and architectures, you will build and evolve native Android and iOS applications, integrating seamlessly with backend services and cloud platforms. If you enjoy building polished mobile products, solving complex platform challenges and shaping the technical direction of a mobile team, this role gives you the autonomy, responsibility and impact to do so.

Key Responsibilities

• Lead the design and development of native Android and iOS applications, ensuring they are scalable, performant, secure and well-architected.
• Provide technical leadership to the squad, guiding decisions on mobile architecture, frameworks, libraries, and best practices in code quality, performance, accessibility and security.
• Remain highly hands-on, spending most of the time writing and reviewing mobile code, and ensuring high-quality, maintainable applications.
• Collaborate closely with backend engineers to design and consume APIs that support robust and efficient mobile experiences.
• Mentor and coach mobile engineers, fostering a culture of continuous learning, strong ownership and technical excellence.
• Own mobile build, release and deployment processes, including CI/CD pipelines and app store submissions for Google Play and Apple App Store.
• Champion automated testing, app stability, observability, and the responsible use of AI to improve developer productivity and software quality.

Knowledge, Skills and Behaviours

• 7+ years of professional software engineering experience, with a strong focus on mobile application development.
• Strong experience building native Android and native iOS applications, with a deep understanding of modern mobile architectures and best practices.
• Previous experience as a Lead Engineer, Tech Lead or Senior Mobile Engineer leading a small team.
• Proven experience integrating AI-assisted development tools and techniques into everyday workflows (e.g. code generation, testing, debugging, performance analysis or automation).
• Hands-on experience integrating mobile apps with backend APIs (REST and/or GraphQL) and cloud-based services.
• Strong focus on testing and quality, with experience using mobile testing frameworks and automated testing approaches.
• Experience owning mobile CI/CD pipelines, build automation and app store release processes.
• An observability mindset, with experience using crash reporting, performance monitoring and analytics tools to improve app reliability.
• Comfortable working with Git, Jira, Confluence and modern agile engineering workflows.
• Proven ability to mentor engineers, review code and designs, and balance pragmatism with mobile engineering excellence.
