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 are looking for an entry-level Power Electronics Engineer who is excited to help bring X-BAT’s next-generation power systems to first flight. In this role, you will own a meaningful project directly tied to our power architecture critical path, while receiving direct mentorship from senior power and electrical engineers. We value first-principles thinking, hands-on engineering, and extreme ownership.

Own a power electronics design that directly impacts X-BAT system performance and major flight test milestones, supported by a senior engineer who provides technical guidance and review.

Contribute to the full hardware lifecycle including concept development, modeling, worst-case analysis, schematic capture, simulation, prototyping, bring-up, verification, integration, and flight test support.

Design and analyze low-voltage and high-voltage power systems including DC-DC converters, inverters, motor controllers, battery systems, power distribution, and protection circuits.

Design systems across power ranges from 10 kW high-power applications while balancing efficiency, thermal constraints, EMI/EMC performance, and reliability.

Partner with ECAD engineers on PCB layout for power density, thermal performance, EMI mitigation, and manufacturability.

Execute hands-on board bring-up, debug, root-cause analysis, and validation using oscilloscopes, power supplies, electronic loads, and other test equipment.

Support environmental, stress, and qualification testing (HALT, vibration, temperature cycling) for aerospace-grade reliability.

Collaborate closely with Mechanical, Embedded, Software, Production, and Aircraft teams to ensure robust system integration and clear interface ownership.

Drive disciplined engineering practices including documentation, risk reduction, and closing the loop between analysis and test results.

B.S. in Electrical Engineering or equivalent.

Strong technical fundamentals in circuits, electronics, and power systems.

Hands-on experience (coursework, labs, clubs, or internships) with power electronics such as converters, motor drivers, batteries, or high-power systems.

Familiarity with electrical design tools (Altium, KiCad, etc.).

Experience using lab equipment such as oscilloscopes, power supplies, e-loads, and multimeters.

Participation in an engineering team/club or hands-on project experience.

Ability to obtain a S//SAR level security clearance desired.
