Job Description:

At Shield AI, we are revolutionizing defense technology to protect service members and civilians with intelligent, autonomous systems. Our Lab Architecture and Infrastructure Test Engineering team plays a critical role in ensuring the X-BAT remains the most reliable, mission-ready UAV in the industry. We design cutting-edge test solutions—custom-built electrical and mechanical systems that push our hardware to its limits in real-world and extreme environments.

As a Senior Architecture and Infrastructure Test Engineer on our Test team, you will own the design and development of test systems that push our hardware to its limits. From designing custom PCBs and automated test sequences to developing electrical and mechanical test stands, you’ll be at the forefront of ensuring the highest reliability in aerospace hardware. This is a high-impact role where your expertise in Lab Architecture, Infrastructure, power electronics, RF, communications, and automation will help shape the future of intelligent defense systems.

What you’ll do:

• Design, validate, and deploy advanced test systems for X-BAT’s critical components and subsystems.

• Architect PCBs and test interfaces for power electronics, RF, and communication systems.

• Develop automated test sequences in Python, ensuring scalability, efficiency, and repeatability.

• Design and integrate custom test fixtures, including relays, PLCs, PCBAs, and harnessing.

• Own and drive cross-functional design reviews, advocating for design-for-testability (DFT) improvements.

• Work hands-on with HASS, ESS, and HALT testing, validating performance in simulated harsh environments.

• Be a technical mentor, guiding junior engineers and contributing to Shield AI’s growing expertise in hardware test engineering.

• Other duties as assigned.

Required qualifications:

• B.S. in Electrical Engineering or related STEM field.

• Typically requires a minimum of 5 years of related experience in hardware design and test engineering (or equivalent experience with advanced degrees).

• Deep expertise in electrical design, mechanical, and software engineering principles as applied to hardware test systems.

• Proven ability to design, implement, and validate multidisciplinary hardware systems in a fast-paced, high-stakes environment.

• Track record of ownership—driving projects from concept to execution, delivering exceptional results.

• A team-first mindset, with high standards for yourself and others, and a passion for solving complex technical challenges.

• Track record of working hard, being a trustworthy teammate, holding yourself and others to high standards, and being kind to others.

• US Citizenship required due to security clearance requirements.

Preferred qualifications:

• Proficiency in Python or another scripting language for test automation.

• Hands-on experience with PCB design tools (Altium, KiCAD, Eagle) and CAD software (SolidWorks, NX, CATIA).

• Experience working in rugged, high-reliability industries like aerospace, defense, or automotive.

• Strong problem-solving skills with the ability to pivot quickly in dynamic, evolving environments.

• Active Top Secret clearance or eligible to achieve
