Wearable Hardware Engineer – PCB, BLE, Firmware & Manufacturing Experience

Job Description
We are looking for an experienced hardware/embedded engineer for an upcoming wearable product development project.
The product is a compact wrist-worn connected device, and we need someone who has previously taken a wearable or similar battery-powered consumer electronics product from hardware design through prototyping and manufacturing.
The device will involve:
- Custom PCB / electronics design
- Bluetooth Low Energy (BLE)
- Microphone + speaker / two-way audio
- Low-power embedded firmware
- Battery and power optimisation
- Wireless charging
- Compact wearable enclosure / CAD
- Prototype development and testing
- DFM and manufacturing handoff
The final project will require complete production-ready deliverables including schematics, PCB/Gerber files, BOM, firmware source, enclosure CAD and assembly/manufacturing documentation.
Most Important Requirement
Please apply only if you have already worked on a real wearable or similarly compact battery-powered consumer product.
In your proposal, please share:
1. 1–3 relevant products you personally worked on
2. Photos, videos, website, App Store/product page, Kickstarter, Amazon or other public link showing the finished product, wherever available
3. Your exact role and responsibilities on each product
4. Whether you handled:
- PCB/schematic design
- Embedded firmware
- BLE
- Battery/power optimisation
- Audio hardware
- Antenna design/tuning
