On-siteEngineeringFull-time
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 we move 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
Requirements
- 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 with 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
- 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
Qualifications
- 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
