You’ll be working alongside and mentoring two other engineers on the project, as well as collaborating closely with a team of designers, testers, and product managers as you drive the technical direction and execution of numerous concepts and approaches, interfacing with custom-built APIs. Our team is empowered to find creative and scalable solutions for a large, demanding user base across the UK and Europe.

About You

✨Skills & Competencies

• Extensive and demonstrable experience leading the development of production-ready applications (Ideally Dart and Flutter but that isn’t a must have).
• Proven experience mentoring junior/mid-level engineers and providing technical guidance.

A deep understanding and practical experience with:

• Leading the development of complex mobile applications for both Android and iOS from conception to launch.
• Advanced Architectural patterns (e.g., BLOC) and the ability to evaluate and select appropriate architectures for new features.
• Complex networking, caching strategy, communication, and performance optimisation.
• Utilising the Bridge pattern to decouple application architecture.
• Complex asynchronous execution and error handling.
• Designing and implementing comprehensive Unit and UI automation test strategies.

Experience with:

• Defining best practices for source control systems and code review processes.
• Integrating, debugging, and optimising complex APIs and backend services.
• Expertise in managing and evaluating third-party dependencies, considering long-term maintenance and security.
• Deep familiarity with the App Store and Play Store publishing process, including CI/CD pipelines (e.g., Fastlane, Gitlab).
• Working in a highly collaborative and fast-paced Agile environment, including leading sprint planning and technical estimations.
• Significant experience leading a concept from its early stages of development through to successful market launch and post-launch optimisation.
• Ideally experience with Dart/Flutter as the existing App has been built using those technologies.

In addition:

• The ability to work autonomously to set and achieve technical goals, proactively reaching out to and influencing other areas of the business, both technical and nontechnical, to drive project success.
• The ability to critically assess conceptual designs and experience flows, challenging assumptions and calling out areas which could be simplified/altered in a way to make their implementation more feasible, effective, and performant from a technical perspective.
• The capability to partner with Product Management, taking ownership of breaking down high-level feature requirements into well-defined, manageable pieces of work that can be built and delivered in an agile fashion, ensuring technical debt is managed effectively.
• Exceptional written & verbal communication skills, and experience working in customer-facing roles, including presenting technical roadmaps and solutions to non-technical stakeholders.
