Embedded Smartwatch Prototype Developer

I’m building an early-stage smartwatch and need a hands-on embedded systems programmer who can also think like a product engineer. The immediate goal is a functional prototype that proves out a low-power voice recognition system on the wrist. Key objectives • Select an appropriate MCU or SoC, define the basic hardware stack, and advise on component sourcing. • Write and flash efficient firmware that boots quickly, manages power intelligently, and exposes clean APIs for future features. • Integrate a voice recognition engine that can run locally (no phone tether) for a small set of commands; latency and accuracy are critical. • Provide basic board-level debugging, over-the-air update hooks, and clear documentation so my in-house app team can build on the firmware later. Deliverables 1. Block diagram and parts list. 2. Compiled firmware with commented source. 3. Test report demonstrating voice command success rate, boot time, and battery draw. 4. Handoff package: flashing instructions, pin map, and recommendations for next hardware spin. If you’ve shipped wearables, optimized for battery life, or worked with on-device speech libraries such as TensorFlow Lite Micro or Sensory TrulyHandsfree, I’d love to see your examples. Let’s create the proof-of-concept that sets the foundation for our full product line.
