Mobile Engineer (Flutter & Native)

Is BLoC always the answer? Does Riverpod truly solve “widget-tree hell”? We believe the right tool depends on the job. If you agree, let’s talk.

We are looking for a Mobile Engineer who is fluent in both Flutter and a native mobile platform (iOS or Android). This is a unique opportunity to work on a diverse portfolio of projects, from high-impact client solutions to our own home-grown products.

What You’ll Do:

• Take a key role in developing new features and extend existing functionality using Flutter and Dart
• Bridge the gap between cross-platform and native development, leveraging your experience in either iOS or Android to solve complex problems
• Write clean, maintainable, and well-tested code that you can be proud of
• Collaborate with the team and clients to define, design and bring new features to life
• Participate in code reviews and provide constructive feedback to other engineers
• Engineer for the Future: Move beyond single-project thinking. Your focus will be on creating reusable, scalable solutions and components that accelerate future client projects and form the foundation of our growing library of digital solutions
• Stay up-to-date with the latest trends and technologies in the mobile and Flutter ecosystems

  What We’re Looking For:

• 5+ years of hands-on experience in Mobile development
• Native development expertise: You have a strong background in either native iOS or Android development
• Proven Flutter experience: You have professional experience building, shipping, and maintaining complex Flutter applications. You can show us the results
• You can talk in-depth about the architectural decisions, challenges, and outcomes of the complex mobile applications you’ve helped build and maintain
• Solid knowledge of the Flutter framework and the Dart programming language: You know the lifecycle of the app, how widgets get rendered
• Experience with state management solutions, such as Riverpod, BLoC or GetX
• Experience with REST APIs and a solid understanding of how to design and consume networked services efficiently
• You can articulate complex technical ideas clearly to both technical and non-technical stakeholders
• Strong understanding of mobile app performance optimization and security best practices
• Practical experience with CI/CD systems and pipelines
• Having experience with developing desktop applications is a plus

What we are primarily looking for is a track record of building things that work and passion to make a better product.
