Senior Power Electronics Engineer: Lead High-Density Motors

Arbeitnow; Lausanne; Vor Ort; CHF 120.000 - 170.000; Vollzeit

Zusammenfassung

Harmattan AI in Lausanne is seeking a senior IC to own the analog power chain end-to-end across UXV platforms, from MOSFET commutation simulation through PCB layout to lab validation. You will be the technical reference on power electronics, unblocking propulsion, airframe, and embedded teams as we scale from prototype cadence to multi-platform deployment.

This is a builder role; you ship hardware, mentor junior engineers, and drive end-to-end design decisions in a demanding, defense-focused

Qualifikationen

• 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.

Aufgaben

• Power Stage Architecture: Lead motor-controller and DC-DC topology across fixed-wing, multicopter, and hybrid UXV platforms.
• 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, 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.
