• Design power electronics for the high voltage and low voltage systems. This includes 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
• You have a B.S. in Electrical Engineering or equivalent
• You have 10+ years of experience as an Electrical Engineer
• You are experienced with: circuit design, schematic capture, component selection, circuit testing, and debugging
• You have a demonstrated record of working hard, being a trustworthy teammate, holding yourself and others to high standards, and being kind to others
• Familiarity with Altium or equivalent
• Ability to obtain a S//SAR level security clearance desired.
