Job description

Principal Power Electronics Engineer

We’re looking for a Principal Power Electronics Engineer to own the design of power electronics and the system they integrate with on the X-BAT aircraft. This includes architecture and converter design, development, and delivery across our aircraft programs. You will define requirements and be responsible for design from concept to production. If you excel in cross‑functional collaboration, thrive in fast‑moving environments, and are passionate about pushing the limits of power system design, we want to hear from you.

Responsibilities

• Own flight critical power system design for X-BAT.
• Design power electronics for the high voltage and low voltage systems, including inverters, DC‑DC converters, battery management, and other power electronics.
• Lead others to execute design, verification, and manufacturing deployment.
• Provide mentorship and technical feedback to others on the power team and cross‑functionally.
• Harden the designs for harsh environments such as shock/vibe, high reliability, radiation, and high altitude.
• Work on power sub‑systems and designs for both low power (<1 kW) and high power (>10 kW).
• Full‑cycle hardware development: Own the entire flow – concept, modeling, worst‑case analysis, schematic capture, simulation, prototyping, design reiteration for improving design maturity, testing and validation.
• PCB ownership: Drive PCB layout and design with ECAD engineers, optimizing for power density, EMI, thermal, and manufacturability.
• Design for Safety, Manufacturability and Reliability: Design robust systems keeping in mind best practices for safety, manufacturing and reliability.
• Cross‑functional collaboration: Work closely with Mechanical, CAD, Embedded, Software, Supply Chain, Test Automation, Production and various aircraft teams throughout the product lifecycle.
• Design review leadership: Lead and contribute to cross‑functional reviews ensuring robust, high‑integrity engineering decisions. Mentor junior engineers that support your design.
• Program execution: Manage project timelines, deliverables, and technical milestones to drive on‑time, high‑quality outcomes.

Qualifications

• B.S. in Electrical Engineering or equivalent.
• 10+ years of experience as an Electrical Engineer.
• Experience with circuit design, schematic capture, component selection, circuit testing, and debugging.
• Demonstrated record of working hard, being a trustworthy teammate, holding yourself and others to high standards, and being kind to others.
