Electrical Engineer I

About the Role

Shield AI is looking for an entry-level Power Electronics Engineer to help bring its next-generation aircraft, XBAT, to first flight. This role offers direct mentorship from senior engineers and involves owning a meaningful project critical to the power architecture. The company values first-principles thinking, hands-on engineering, and extreme ownership.

Key Responsibilities

• Own a power electronics design impacting X-BAT system performance and flight test milestones, with technical guidance and review from a senior engineer.
• Contribute to the full hardware lifecycle: 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 <1 kW to >10 kW, 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 with Mechanical, Embedded, Software, Production, and Aircraft teams for robust system integration.
• Drive disciplined engineering practices including documentation, risk reduction, and closing the loop between analysis and test results.

Requirements & Tech Stack

• 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 such as Altium or KiCad.
• Experience using lab equipment including 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 is desired.
