f7d8749a-72d6-407c-bf98-292ea630c73a The Power Electronics - Electrical Engineer II designs, analyzes, and validates power electronics systems for autonomous aircraft, including HV and LV power systems and embedded safety mechanisms. The role involves full-cycle hardware development and cross-functional collaboration.

Responsibilities

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.
Design Power Electronics: Design of HV and LV systems including:
High-voltage and low-voltage power systems
DC-DC converters, inverters, and motor controllers
Battery, Battery management, power generation, and distribution
Embedded safety and protection mechanisms
Design across power ranges: Engineer solutions from 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
