Let’s Build a Unicorn Together [Equity Role]

We're not just building an app — we’re building a movement. Halen is a user-friendly Super App that unifies essential lifestyle services into one beautifully designed experience. Think rideshare, grocery and food delivery, retail delivery, vacation rentals, and even flight bookings — all in one place.

This is your chance to join a mission-driven startup at the ground floor as a core team member. We’re lean, ambitious, and building for scale — and we want someone just as passionate to lead Flutter development and help us bring the Halen vision to life.

What You’ll Do:

  • Lead the design, development, and optimization of Halen’s cross-platform mobile application using Flutter
  • Build intuitive and performant UI with Dart and Flutter for both iOS and Android
  • Collaborate closely with product, design, and backend teams to deliver seamless, scalable features
  • Ensure code quality through unit testing, CI/CD pipelines, and modern best practices
  • Optimize app performance and scalability for a super app with multiple integrated services
  • Contribute to architectural decisions and help shape our evolving tech stack

What We’re Looking For:

  • 4–6+ years of mobile development experience with a strong focus on Flutter
  • Proficiency in Dart and the Flutter framework (including widgets, state management, animations)
  • Experience with RESTful APIs, Firebase, and third-party SDK integration
  • Familiarity with architectural patterns like BLoC, Provider, or Riverpod
  • Experience shipping apps to the App Store and Google Play
  • Bonus: Experience with GraphQL or microservices
  • Strong product mindset — you care about user experience and seamless cross-platform flow
  • Self-starter who thrives in fast-paced, startup environments
  • Excellent communication and a collaborative spirit

What You’ll Get:

  • A chance to shape a category-defining product from the ground up
  • Significant equity (20,000–150,000 shares based on performance/milestones)
  • Flexible remote work with the potential to transition to full-time post-launch
  • An entrepreneurial team that's obsessed with building great products
  • Real ownership — your work will directly impact our success

If you’ve ever wanted to build the next big thing from zero to one — this is your shot.
