Senior Flutter Developer (Freelance)

Join intent, a fully remote software studio, as a Senior Flutter Developer on a freelance basis. We're looking for an experienced engineer who can build production-ready Flutter applications that control hardware devices over Bluetooth Low Energy (BLE) connections, working with clients across wearables, smart audio, and health-tech sectors.

What This Role Involves

You'll develop and enhance Flutter applications that serve as the interface between users and sophisticated hardware ecosystems. Your work will span both iOS and Android platforms, requiring deep understanding of how app-level code translates into tangible device behavior. You'll collaborate with firmware teams, industrial designers, and product managers to ship applications that don't just compile on multiple platforms—they deliver a seamless user experience regardless of the operating system. This isn't template work; it's specialized development where your code directly controls real-world devices and sensors.

Day-to-Day Responsibilities

• Architect and build Flutter applications communicating with Bluetooth peripherals, ensuring reliability across edge cases
• Develop iOS and Android implementations that maintain consistent behavior and performance
• Participate in technical planning, feature estimation, and architectural decisions with the broader team
• Debug complex issues discovered through QA, including hardware-specific problems that require detective work
• Review code contributed by teammates and provide mentorship through constructive feedback
• Share technical knowledge through documentation, peer programming sessions, and team presentations
• Integrate AI-assisted development tools into your daily workflow as a force multiplier
• Coordinate with cross-functional teams including designers, product leads, and hardware engineers

What You Bring

• Expert-level Flutter development experience, including production deployments on iOS and Android
• Hands-on background with BLE integration and hardware communication protocols
• Proven track record shipping apps that interface with physical devices
• Ability to think critically about requirements and propose better approaches
• Ownership mindset: you take responsibility for code quality and system reliability
• Comfort with modern AI tools as everyday development aids
• Strong written and verbal communication skills
