Your primary focus will be on our mobile applications (iOS/Android), built using React Native, while working closely with our backend services built in Ruby (Rails) with a Postgres database.

- User Interface Excellence: Develop highly interactive, user-centric mobile applications with responsive UI/UX designs that ensure a seamless experience across iOS and Android.
- Code Quality & Collaboration: Actively participate in code reviews to maintain high standards, providing constructive feedback to peers and incorporating feedback into your own work.
- Mentorship: Actively mentor junior and mid-level engineers, fostering a culture of continuous learning and technical excellence within the mobile team.
- Debugging & Maintenance: Proactively debug and resolve complex technical issues in production to ensure high app stability and performance.
- Engineering Leadership & Advocacy: Proactively identify inefficiencies in our mobile development workflow or tooling (e.g. CI/CD, deployment pipelines) and lead the implementation of solutions. You will champion high-quality standards and hold the team accountable for best practices.
- Continuous Improvement: Stay up-to-date with industry trends and emerging mobile technologies, bringing fresh ideas to the team to improve our mobile codebase, organisation, and automatisation.
