• Design, build, and maintain Android apps that communicate with hardware peripherals over BLE • Write performant, reusable, and reliable Kotlin code, the kind people don't dread inheriting • Take part in specifying, planning, and estimating new modules and features • Cover your code with unit tests and keep a TDD mindset where it makes sense • Review pull requests and give your teammates feedback that actually helps • Hunt down bottlenecks and bugs, including the ones that only show up on one OEM • Share what you learn: tech talks, internal docs, pair sessions, whatever fits • Use AI tools as part of your daily workflow, not as a party trick

• Own the mobile side of a connected-product project: wearables, smart sensors, health-tech devices • Design and implement BLE communication flows that hold up in the real world • Debug real-world device interactions, including the ones that only happen on one phone in one room • Work side by side with firmware engineers, backend, designers, QA, and PMs • Contribute to architecture and technical decisions, not just execute someone else's • Communicate directly with the client: you won't be hidden behind layers of management • Use AI tools as part of your daily workflow, not as a party trick
