Role Overview

We're looking for a Mid-Weight Flutter Developer based in Portugal to join our engineering team.

This is an exciting opportunity for someone who enjoys owning product features from concept to release, collaborating closely with designers and product teams, and building clean, scalable code.

What You'll Do

  • Collaborate with product designers, backend engineers, and founders to bring ideas to life.
  • Implement UI/UX designs with attention to responsiveness, animation, and seamless user journeys
  • Optimise app performance, memory usage, and offline capabilities.
  • Integrate APIs and maintain data flow between the app and backend services.
  • Participate in code reviews and technical planning.
  • Contribute ideas for improving usability, engagement, and new product features.

  • Troubleshoot bugs, prioritise fixes, and continuously improve overall app stability.

  • 2-4 years of experience working with Flutter/Dart in a production environment.

  • Experience working with REST APIs and Firebase.
  • Strong knowledge of mobile architecture patterns and application lifecycle.
  • Understanding of performance tuning, app profiling and debugging tools.
  • Experience with automated testing, CI/CD pipelines, and app store deployment.
  • A team player mindset, clear communication style, and proactive attitude.
  • Fluency in English.

Nice to Have

  • Experience with fitness, health-tracking, or wearable integration (Strava, Garmin, Apple HealthKit, Google Fit).
  • Hands-on experience with animations and custom UI components.
  • Familiarity with analytics tools (Mixpanel, Firebase Analytics, Rudderstack).
  • Start-up experience and ability to thrive with ambiguity.
  • Good understanding of backend/cloud systems (Firebase and GCP), Kotlin and Swift.
