Your Flutter experience might come from production work, or from a strong native background plus substantial Flutter projects. * Strong understanding of mobile DevOps practices, including CI/CD pipelines, release management, and app store deployment processes. * Advanced software engineering skills, including writing high-quality code, conducting thorough code reviews, and proactively identifying anti-patterns and maintainability risks. * Comfortable using AI coding tools to work faster, with the judgement to know when to rely on them and when not to. You own the code you ship, however it was produced. * Proven ability to diagnose, troubleshoot, and resolve defects across the mobile application lifecycle. * Solid knowledge of reactive state management patterns and how to apply them in mobile architectures. * Strong grasp of software architecture principles, with the ability to communicate and document designs clearly for both technical and non-technical audiences. * Experience building products on top of a design system - consuming and extending shared components rather than reinventing them, and knowing when something belongs in the shared library rather than in your feature. How you work * Strong passion for mobile UX and building inclusive products, with working knowledge of accessibility best practices and relevant standards. * A clear communicator who listens well and collaborates deliberately across product, design and engineering - comfortable working autonomously, and equally comfortable inside a cross-functional team. * High ownership: you turn ambiguous problems into shipped solutions, prototyping early to validate ideas, and take the initiative on improvements rather than waiting to be asked. Nice to have * Native Android (Kotlin) or iOS (Swift) experience. Our legacy native apps are still live, and a native background helps when working out what existing behaviour we need to carry across. * Experience working in finance, investing, or another regulated domain. * Experience with backend-for-frontend architectures, where the backend shapes what the app renders. * Experience building or owning a design system or shared component library., We offer hybrid working, with a minimum of 50% of your working time per month spent in the office. For new starters, there's an initial period of full-time office working to help you settle in and build relationships. ## Description This is a hands-on individual contributor role in a cross functional team. You won't line-manage, but you will have a strong influence on how the team builds - through pairing, code review, mentoring and the technical standards you set. * Architect solutions with your team and write the technical documents that define what we're building. * Write well-formulated, testable and readable code using appropriate software paradigms. * Multiply the team's output - unblock others, make the difficult architectural calls, and leave the codebase easier to work in than you found it. * Ensure accessibility is at the forefront of our approach. * Mentor and develop others in the team, through pairing, reviewing pull requests, and advocating development standards to be followed by existing and new team members. How we build We care more about how you think than which packages you've used, but this is the shape of the work. * A Flutter monorepo - one app plus a set of internal packages. * Layered Clean Architecture, enforced in CI. * A design system built from Figma design tokens and catalogued in Widgetbook. * A backend-for-frontend that drives parts of the UI, so screen composition can change without an app release. * GitHub Copilot for every engineer, with repo-level instructions and custom skills we've built to keep AI output aligned with our architecture and patterns. ## Related Videos - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Intro to Flutter Development](https://www.wearedevelopers.com/videos/170-intro-to-flutter-development) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) - [Why Kotlin is the better Java and how you can start using it](https://www.wearedevelopers.com/videos/661-why-kotlin-is-the-better-java-and-how-you-can-start-using-it) ## Related Articles - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter) - [Flutter Developer Salary [2023]](https://www.wearedevelopers.com/magazine/199-flutter-developer-salary-2023) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [8 No-Code App Builders](https://www.wearedevelopers.com/magazine/300-8-no-code-app-builders) - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
