Job Description:

Shield AI is redefining autonomous aviation with cutting-edge AI and GPS/RF-denied navigation technologies. Now, we’re building our next-generation aircraft, XBAT, like no other—one that will push the boundaries of innovation and performance.

We’re looking for a Power Engineer II to contribute to the design, analysis, and validation of power electronics systems critical to our aircraft. This role is perfect for an engineer with a solid foundation in power systems who is eager to grow, own challenging projects, and see their work move rapidly from concept to flight. If you thrive in fast-paced environments, enjoy solving complex problems, and want to help build the future of autonomous aviation, we want to hear from you.

What you’ll do:

• Design Power Electronics: Design of HV and LV systems including:
• Design across power ranges: Engineer solutions from <1 kW low-power systems to >10 kW high-power applications
• 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
• Board Bring Up and Testing: execute board bring up, verification, validation and HALT testing to meet rigorous aerospace reliability standards
• Cross-functional collaboration: Work closely with Mechanical, CAD, Embedded, Software, 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
• Program execution: Manage project timelines, deliverables, and technical milestones to drive on-time, high-quality outcomes

Required qualifications:

• You have a B.S. in Electrical Engineering or equivalent
• You have 1+ 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
• You have experience with lab equipment: oscilloscopes, power supplies, E-loads, multimeters, etc.
• Ability to obtain a S//SAR level security clearance desired.
