Senior Flutter Developer
Remote | 3-Month Unpaid Opportunity | Part-Time / Flexible
LYNA is a women’s health and nutrition app helping women better understand the connection between their menstrual cycle, nutrition, weight, and hormonal health.
We’re looking for a Senior Flutter Developer to join us remotely for an initial 3-month unpaid engagement and help take LYNA’s mobile experience to the next level.
This is an opportunity to work directly on a real product with an existing user base and meaningful impact — not a hypothetical side project.
About LYNA
LYNA provides personalized, cycle-aware nutrition guidance, including:
- Menstrual cycle tracking and phase-based insights
- Meal and nutrition tracking
- Food/meal photo scanning
- Macro and micronutrient tracking
- Personalized calorie and weight goals
- Nutrition guidance for areas such as PCOS, fertility and perimenopause
- Evidence-informed health and nutrition recommendations
LYNA already has 15,000+ users, and we're continuing to improve and scale the product.
The Role
As our Senior Flutter Developer, you’ll take ownership of the mobile application and work closely with the product/founding team to build, improve and maintain LYNA.
You’ll have significant influence over the technical direction of the Flutter app, architecture, user experience and development practices.
What you’ll do
- Develop and maintain LYNA’s iOS and Android applications using Flutter/Dart
- Build polished, responsive and intuitive mobile experiences
- Translate Figma/product designs into high-quality production interfaces
- Integrate REST APIs and third-party services
- Work with authentication, user profiles, subscriptions and app data
- Implement health, nutrition and cycle-tracking features
- Work with image/meal-scanning functionality and AI-powered experiences
- Improve application performance, reliability and scalability
- Identify and resolve bugs and technical issues
- Refactor and improve existing code where necessary
- Help establish and maintain a clean, scalable Flutter architecture
- Write maintainable, well-tested and production-ready code
- Participate in technical/product discussions and contribute to product decisions
- Help prepare the application for continued growth and future releases
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

Required:
- 5+ years of professional software development experience
- Strong commercial experience with Flutter and Dart
- Experience shipping and maintaining production Flutter applications
- Strong understanding of mobile app architecture and state management
- Experience integrating APIs and backend services
- Strong knowledge of Git and modern development workflows
- Experience debugging and optimizing mobile applications
- Good understanding of iOS and Android development considerations
- Strong attention to UI/UX quality
- Ability to work independently and take ownership of technical decisions
- Comfortable working remotely in a fast-moving startup environment
Nice to have:
- Experience with health, wellness, nutrition or fitness apps
- Experience with AI/ML-powered mobile features
- Experience with camera/image processing or food recognition
- Experience with Firebase
- Experience with payments/subscriptions and RevenueCat
- Experience with analytics and crash reporting
