Power Electronics Engineer

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.

• 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.

• 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.

• Core technical skills:

  • 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

• What we value

  • 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
