Location: Switzerland
Workplace: Onsite
Employment Type: Full time
Job Function: Energy & Utilities Operations

Key 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.

Key Requirements

  • •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): ideally on drone, robotics, eVTOL, or automotive platforms.
  • •Fluency in simulation (LTspice, PLECS, or Simulink) and PCB design (Altium).
