About The Position

We're looking for a hands-on HV Power Electronics Engineer to own drive architecture and PCB design for a novel actuator platform targeting humanoid robotics. This is not a conventional motor-drive role: you will define the power electronics architecture for an actuator whose electrical behavior, sensing constraints, packaging limits, and efficiency targets do not map cleanly to an existing inverter template.

Requirements

• Education: BS, MS, or PhD in Electrical Engineering or equivalent.
• Experience: 3+ years in analog/power electronics with HV experience (>100V), including end-to-end ownership of boards from schematic through bring-up and debug.
• Gate drive design for HV switching; SPICE simulation; transient, fault, and protection design
• Mixed-signal PCB layout — HV/LV isolation, current loops, return path control, noise partitioning, and compact packaging
• EMI/EMC in mixed-signal environments: pre-compliance scanning, LISN use, isolation strategy, and board-level mitigation
• Comfort designing for loads and sensing schemes that do not come with a standard reference architecture

Nice To Haves

• First-principles fluency — form a correct mental model of a new electromechanical system and turn it into a robust, efficient electronics architecture
• Good engineering judgment under hard size, weight, thermal, and efficiency constraints
• A builder mindset: ship hardware, find failures fast, iterate

Responsibilities

• Drive Architecture: Design the HV analog front-end and multi-phase switching stage; define gate drive topology, protection, edge-rate control, operating envelope, and efficiency strategy from first principles.
• PCB Design: Own schematic, layout, bring-up, and debug through multiple board revisions — open-loop drive → integrated sense and MCU → production-intent.
• Sense Channel: Design position readback that coexists with HV switching on the same substrate; build the measurement chain and extraction strategy needed to recover usable signals in a hostile electrical environment.
• EMI Mitigation: Architect isolated rails, return paths, slew-rate control, and switching transitions; own pre-compliance EMI scanning and the design changes required to pass it.
• Packaging & Interconnect: Define routing from driver board to actuator across a multi-layer assembly — evaluate flex/rigid-flex vs. wire harness against creepage, clearance, EMI coupling, mass/volume, and assembly constraints.
