Senior R&D Electrical Engineer – San Diego, CA I’m hiring a Senior R&D Electrical Engineer for an implantable neurotechnology company developing next-generation implantable electronics. This is a hands-on, technically deep role owning the electrical and programmable-logic design of the implant from concept through design verification. What You’ll Do Architect and develop synthesizable HDL (VHDL or SystemVerilog) for a low-power FPGA serving as the implant’s health, status, control, and communications controller Implement supervisory functions: power sequencing, voltage/current/temperature monitoring, watchdogs, fault detection, and safe-state transitions Define and implement the implant side of a high-speed serial link to distributed sensing electronics, proven in FPGA emulation with silicon partners ahead of hardware Design fault-tolerant control and monitoring logic, including redundant monitors, independent shutdown paths, and fail-safe defaults; lead FMEA and fault-tree analysis per ISO 14971 Own the implant’s electrical architecture, including custom silicon integration, inductive charging, RF telemetry, and power budgeting Lead miniaturized PCB and flex-rigid design in Altium Define and execute electrical and FPGA verification plans within design controls (IEC 60601-1, IEC 62304, ISO 14708) Review and debug firmware and test software alongside the firmware team; support design transfer to contract manufacturers What You Bring BS in Electrical Engineering, Computer Engineering, or related field 8+ years in mixed-signal hardware design for miniaturized, high-reliability electronic systems 5+ years of hands-on FPGA development on low-power families, including timing closure, clock-domain crossing, and simulation-based verification Serial interface design experience: LVDS/CML signaling, source-synchronous or CDR schemes, framing and error detection, SPI/I2C, register maps Design of safety-relevant or fault-tolerant digital systems Hands-on inductive power transfer or resonant/magnetics design High-density PCB and flex design in Altium; SPICE and signal-integrity analysis Ability to read, debug, and review embedded C firmware Experience taking electronic subsystems from prototype through design verification into production Nice to Have Active implantable device experience (neurostimulators, cochlear implants, cardiac rhythm devices) Custom silicon co-design and FPGA emulation of partner RTL Functional safety standards (IEC 60601-1 PEMS, IEC 61508, ISO 26262, DO-254) Implantable or body-worn antenna/RF design with EM simulation (HFSS, CST, COMSOL) Coil design and EM/thermal modeling, including MRI compatibility Low-noise neural or bioelectric front-end design Experience supporting IDE, PMA, or 510(k) submissions
