Principal Powertrain Engineer, Omen

Anduril Anduril · Defense · Costa Mesa, CA · Maritime & Maneuver Dominance : Maneuver Dominance Engineering : MD - ME

This role is for a Principal Powertrain Engineer at Anduril, a defense technology company. The engineer will design, develop, and integrate a high-performance hybrid-electric propulsion system for the Omen autonomous air vehicle. Responsibilities include owning powertrain component design from concept to production, optimizing for VTOL operations, leading testing and validation, and collaborating with cross-functional teams. The role requires significant experience in powertrain engineering and leadership, with a focus on electric or hybrid propulsion systems for aerospace platforms.

What you'd actually do

  1. Own the design of hybrid-electric propulsion systems including motors, generators, battery packs, fuel systems, power electronics, and propeller/rotor integration
  2. Electric machine sizing and design, transmission sizing and design, inverter sizing and design, and how the full system integrates into the air vehicle.
  3. Conduct powertrain performance analysis, thermal modeling, and energy optimization studies to meet mission requirements for endurance, payload capacity, and operational envelope
  4. Lead the development and execution of test plans for powertrain subsystems and full-up systems, including ground test stands, HILs, and flight test
  5. Define and validate technical performance measures including power, efficiency, thermal limits, and fault tolerance across all operating modes
