Electronics Engineer (Panama City) — wearable / flex Pcb + Ble + inductive charging

Description: Small, paid prototype project — design and prototype a ring-scale flexible pcb for a smart ring: ble (phone control on/off + pwm dim), group dimming of up to 6 leds (3–5 v), single-cell lipo (≈30 mah), inductive charging (flat coil). Must have: PCB layout experience (Altium/KiCad), flexible or rigid-flex experience, experience with BLE modules (nRF/DA14531 or similar) and LiPo charging/Qi receiver work. Please attach 2–3 portfolio examples (flex pcb or small wearable projects) and your hourly rate or fixed price for prototyping (schematic + pcb + first prototype). Panama City based or able to meet locally preferred.

Deliverables: schematic, pcb layout (rigid-flex), bom, prototype assembly, basic firmware to set pwm via ble (gatt).

Timeline: estimate and availability.

Budget: open — provide estimate.
