About The Position

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include Hivemind autonomy software, V-BAT and X-BAT aircraft, and Aechelon simulation and synthetic reality technologies. With offices and facilities across the U.S., Europe, the Middle East, and Asia-Pacific, Shield AI’s technology actively supports operations worldwide. This role involves designing complex electro-mechanical solutions for high voltage power electronics packaging, electrical interconnects, thermal management, and aircraft integration. The engineer will execute analyses to ensure survivability in harsh environments, including structural, thermal, vibration, clearances, and PCBA hardening. They will also ensure avionics meet performance, safety, environmental, and EMI/EMC compliance standards, such as DO-160, DO-254, DO-178C, MIL-STD-810, and MIL-STD-461. The position requires owning design work from concept to implementation, through system verification and validation, and collaborating with electrical engineers and PCB designers to ensure full scope board design and packaging meets product demands.
