About Omi Omi is building wearable AI hardware that lives on you and works with you. Our devices are small, worn all day, and packed with sensors — which means our PCBs are some of the most constrained boards you will ever design. The Role Part-time PCB Design Engineer based in or near Shenzhen. Own schematic capture and PCB layout for our next-gen wearable hardware, from first spin to production. Remote with occasional on-site sessions at our factory in Shenzhen. What you will do • Schematic capture and high-density PCB layout in KiCad • Design compact multilayer boards (4-8+ layers) with aggressive area and height constraints • Antenna layout and RF tuning for BLE and other wireless protocols • Signal integrity and impedance-controlled routing • DFM review and collaboration with CM partners in Shenzhen What we are looking for • Strong KiCad experience — required • Proven track record with 4+ layer boards in tight form factors (wearables, earbuds, IoT) • Antenna design and RF layout experience • Flex or rigid-flex PCB design a strong plus • Experience working with Shenzhen manufacturers
