• Mentor and support developers across the team, promoting quality and continuous improvement

• Implement and maintain robust state management approaches using technologies such as BLoC, Cubit or Redux

• Manage and optimise large-scale codebases, shared libraries and monorepo-based development environments

• Ensure security best practices are embedded throughout the application lifecycle, including authentication, certificate pinning and device attestation

• Design and maintain comprehensive automated testing strategies across unit, component and integration testing

• Monitor and improve test coverage and quality standards across the platform

• Profile, troubleshoot and optimise application performance across mobile and web environments

• Own and improve CI/CD pipelines, preferably using GitHub Actions

• Identify and prioritise technical debt while balancing ongoing feature delivery

• Contribute to planning, architecture discussions and continuous improvement activities across the team

What We're Looking For

• 7+ years' software engineering experience with significant experience building mobile applications

• Strong commercial experience developing cross-platform applications using Flutter and Dart

• Previous experience in a technical lead or senior engineering role

• Deep understanding of reactive state management patterns including BLoC, Cubit or Redux

• Experience working with monorepos and managing shared dependencies across multiple applications

• Strong understanding of mobile and web security principles

• Proven experience implementing automated testing frameworks and quality strategies

• Strong knowledge of performance profiling, troubleshooting and optimisation techniques

• Experience designing and supporting CI/CD pipelines

• Excellent problem-solving skills and a pragmatic approach to delivery

• Strong communication skills and experience working closely with technical and non-technical stakeholders

Nice to Have

• Experience with React Native or Kotlin Multiplatform (KMP)

• Experience working on enterprise-scale or consumer-facing mobile platforms

• Experience with cloud-native architectures and services

• Exposure to regulated or security-sensitive environments

• Experience leading distributed teams

• Familiarity with modern observability and monitoring tooling
