Senior Electrical Engineer in San Francisco

Job Description About the role We're partnering with a well-funded robotics startup building an integrated hardware and software platform for embodied AI. The team is developing a new of general-purpose robots alongside the software stack that runs them, with the goal of making robots far easier to build, program, and deploy. This is an early, high-ownership environment where your hardware ships on every unit. We're looking for a Senior Electrical Engineer to design, develop, and validate the core electrical subsystems of general-purpose robot platforms. You will own power electronics, motor drive circuits, sensor integration, and PCB design, from schematic through bring-up to production-ready hardware. This is a hands-on, high-ownership role. You will make architecture decisions, drive subsystems end to end, and be accountable for hardware that ships on every unit. Responsibilities Own end-to-end design of power electronics subsystems: battery management, power distribution, protection circuits, and DC-DC conversion Design and validate motor drive circuits for high-performance actuation, including FOC/BLDC/PMSM control topologies Design sensor integration circuits for IMUs, encoders, hall-effect sensors, force/torque sensors, and thermal sensors Create schematics and multi-layer PCB layouts using industry-standard EDA tools (e.g., Altium, Cadence Allegro, KiCad), owning the full cycle from concept through layout review, prototype bring-up, and production release Perform circuit simulation (LTspice or equivalent) and systematic hardware validation using oscilloscopes, current probes, power analyzers, and spectrum analyzers Apply EMI/EMC design principles from the start; support FCC, CE, and UL certification as the product moves toward commercial deployment Drive DFM/DFA decisions to ensure designs are manufacturable and testable at production scale Instrument boards and conduct board-level bring-up, power-on sequencing, and subsystem verification Collaborate daily with firmware engineers on hardware/software interfaces and with mechanical engineers on physical integration and thermal constraints Document designs with the rigor required for CM handoff and engineering review Minimum qualifications 5+ years of electrical engineering experience in robotics, industrial automation, automotive, or consumer electronics, with at least one product shipped to production Hands‑on PCB design experience in industry-standard EDA tools (Altium, Cadence Allegro, KiCad, or equivalent) for complex, multi-layer boards combining high-speed digital, power, and mixed-signal on the same design Proven experience designing power electronics: BMS, power distribution, protection circuits, or DC-DC conversion Motor drive design experience: BLDC, PMSM, or servo drive circuits, ideally with FOC topology Strong bench skills: oscilloscope, current probe, power analyzer, logic/spectrum analyzer, signal integrity debug Ability to read and interpret electronic circuit diagrams; comfortable integrating sensors and actuators Experience with DFM/DFA and working directly with contract manufacturers Experience designing complex multilayer PCBs (8+ layers), including controlled impedance routing, mixed-signal design, and high‑speed differential pairs qualifica tions Experience taking a product through FCC, CE, or UL certification, including EMC pre‑compliance testing Functional safety design experience (ISO 26262, IEC 61508, or equivalent) Familiarity with embedded firmware at the hardware/firmware boundary, enough to co‑debug with firmware engineers without needing translation Experience with high‑density or thermally‑constrained PCB layouts Background in production test fixture design and manufacturing ramp Proficiency in Python or similar scripting for test automation Hands‑on use of AI‑assisted EDA or coding tools in your design workflow #J-18808-Ljbffr Energy Jobline ZR
