About the role

Senior IC-level power electronics engineer responsible for end-to-end analog power chain design for UXV platforms, including MOSFET commutation, gate-drive design, multi-fidelity simulation, PCB layout, lab validation, and production readiness. Builder role focused on delivering hardware for propulsion, airframe, and embedded teams at Harmattan AI.

Responsibilities

  • Power Stage Architecture: Lead motor-controller and DC-DC topology across fixed-wing, multicopter, and hybrid UXV platforms. Translate mission constraints into power-chain specification.
  • MOSFET Commutation & Gate-Drive Design: Own the analog switching design: dead-time tuning, gate shaping, switching-loss vs EMI vs thermal trade-offs.
  • Multi-fidelity Simulation: Deploy the full stack: analytical loss budgeting, transient SPICE (LTspice), system-level modelling in PLECS or Simulink.
  • BLDC Drive Stages: Design three-phase inverters with integrated current sensing, protection, Trapezoidal and FOC-aware hardware interfaces.
  • High-Power-Density PCBA: Lead schematic and layout in Altium or KiCad with thermal, parasitics, and EMC engineered in from the first revision.
  • EMI / EMC Engineering: Drive pre-compliance, filter design, and root-cause debug under flight-representative loads.
  • Prototype-to-Production: Take motor-controller PCBAs through revision discipline, DFM, and qualification - closing the loop on field returns.
  • Lab Validation: Execute bench characterization (power analysers, oscilloscopes, thermal imaging, double-pulse testing) and reconcile against simulation.
  • Firmware & Controls Interface: Partner with embedded and propulsion on FOC tuning, current-sense calibration, and the hardware/firmware compensation boundary.
  • Design Authority & Mentorship: Set the bar via design-decision records and reference designs. Mentor 1–2 junior engineers.

Qualifications

  • MSc or PhD in Electrical Engineering, Power Electronics, or equivalent.
  • 5+ years of hands-on R&D experience on motor drives, BLDC/PMSM controllers, or high-power-density power electronics.
  • Deep working mastery of MOSFET commutation design: gate-driver selection, dead-time tuning, switching transitions, loss budgets.
  • Proven ownership of at least one motor-controller PCBA shipped from prototype through production (or pre-production qualification).
  • Fluency in simulation (LTspice, PLECS, or Simulink) and PCB design (Altium).
  • Strong, hard-earned intuition for EMI / EMC design and debug.
  • Lab-bench discipline: you've personally debugged what simulation missed.
  • Comfort with scale-up iteration speed and end-to-end ownership.
  • English fluent (working language); French is a nice-to-have, not a requirement.
