Senior Flutter Developer

We're looking for a Senior Flutter Developer to join a high-performing engineering team and play a key role in building, evolving and optimising modern mobile applications and SDKs.

You'll combine strong Flutter expertise with deep native mobile experience, working closely with engineers, product managers, designers, QA and Dev Ops to deliver high-quality experiences for customers.

This is a role for someone who enjoys solving complex technical problems, cares deeply about engineering quality and is excited by the evolving world of AI-assisted and agentic software development.

• Work collaboratively with your team to achieve shared product and engineering delivery objectives.
• Actively contribute to team ceremonies, planning, technical discussions and day-to-day delivery.
• Translate product and engineering requirements into clear technical solutions and implementation tasks.
• Take ownership of code quality, with strong automated test coverage and a focus on minimising defects.
• Participate in code reviews, helping maintain high engineering standards and consistent coding practices.
• Identify opportunities to improve technical processes, architecture, performance and developer experience.

• 4+ years' commercial Flutter experience, with strong expertise writing testable and maintainable Dart.
• Extensive experience building production-grade Flutter applications and a strong understanding of modern architectural patterns, including Clean Architecture and BLoC/state management.
• Strong knowledge of Flutter widgets, frameworks and automated testing, including Widget Testing.
• Comfortable working with TDD, with an understanding of BDD within a Flutter environment.
• Experience using AI and agentic coding tools, such as Anthropic and OpenAI, as part of the software development lifecycle.

• Firebase SDKs, including Crashlytics and Remote Messaging.
• One Signal.
• Server-Driven UI.
• Modern approaches to AI-assisted software engineering and developer tooling.

We're looking for someone who is proactive, collaborative and takes genuine ownership of their work. You'll be expected to contribute beyond simply writing code - helping shape technical decisions, improve ways of working and raise the engineering bar across the team.

You'll also need to be available throughout the working day, with occasional flexibility for early or late activities where required, and operate in line with the organisation’s values, policies and procedures.
