You will work on new aircraft development in a lean, high-ownership culture where you directly shape the product and operate at a velocity to fly new designs within months, not years.

In this role, you will design, develop, and integrate a high-performance hybrid-electric propulsion system into the Omen air vehicle. You will own and design powertrain components from concept through production, optimizing for the unique demands of a tail-sitter platform including VTOL operations, efficient cruise flight, and rapid transition between flight modes.

As a Principal Powertrain Engineer, you will work closely with program leadership and cross-functional teammates to deliver a high-performance, reliable propulsion solution. You will drive component selection, manage supplier relationships, lead testing and validation efforts, and ensure the powertrain meets performance, weight, thermal, and reliability requirements.

This is a hands-on role where you will tackle hard technical problems, mentor junior engineers, and play a critical role in bringing a groundbreaking aircraft platform to operational reality. You will be a trusted subject matter expert in the design and development of our powertrain.

Join our dynamic team and help us build the next generation of autonomous flight systems.

Key Responsibilities:

• Own the design of hybrid-electric propulsion systems including motors, generators, battery packs, fuel systems, power electronics, and propeller/rotor integration

• Electric machine sizing and design, transmission sizing and design, inverter sizing and design, and how the full system integrates into the air vehicle.

• Conduct powertrain performance analysis, thermal modeling, and energy optimization studies to meet mission requirements for endurance, payload capacity, and operational envelope

• Lead the development and execution of test plans for powertrain subsystems and full-up systems, including ground test stands, HILs, and flight test

• Define and validate technical performance measures including power, efficiency, thermal limits, and fault tolerance across all operating modes

• Create detailed technical specifications and interface control documents for powertrain components and assemblies

• Collaborate with the Airframe and Vehicle Controls teams for solutions on system packaging, structural/thermal interfaces, and thrust/power control architectures

• Conduct design reviews, perform requirements analysis, and plan system verification to ensure compliance with project goals and industry standards

• Establish and manage supplier relationships for critical powertrain components, including technical requirements definition, design reviews, and qualification oversight

Required Qualifications:

• High-ownership and a bias toward action – if you see a problem, you want to fix it

• Bachelor's degree in Aerospace Engineering, Mechanical Engineer, Robotics, Physics, or related technical discipline

• Minimum of 12+ professional years in technical leadership roles such as a Principal Engineer, Chief Engineer, or similarly relevant position focused on propulsion systems

• Experience in engineering team leadership and project execution for aerospace, automotive, or defense sectors with focus on electric or hybrid propulsion

• Proficiency in powertrain engineering skillsets including electric motors, transmissions, generators, power electronics, battery systems, and thermal management

• Hands-on experience with propulsion system development, testing, and integration for aerospace platforms

Preferred Qualifications:

• Direct experience developing hybrid-electric or electric propulsion systems for aircraft, rotorcraft, eVTOL, or UAS platforms

• Proven track record leading propulsion systems through full qualification campaigns from early development through flight test and production

• Experience with propulsion system modeling and simulation tools

• Familiarity with aviation environmental and EMI standards (MIL-STD-810, MIL-STD-461, DO-160, or equivalent) and qualification campaigns for flight hardware

• Experience with Formula SAE, Baja SAE, Design Build Fly, or similar competitive engineering programs demonstrating hands-on vehicle integration experience
