Principal Electrical Engineer, Integration & Test

Principal Electrical Engineer, Integration & Test

On behalf of our client, a company building a commercial microreactor, we're hiring a Principal Electrical Engineer to own the end-to-end electrical integration and test infrastructure for the reactor's control system. As the first dedicated hire on the Integration & Test team, you will build the hardware-in-the-loop test environment from a clean sheet and establish the foundational platform used to validate the complete reactor control system ahead of commercial deployment.

This is a high-visibility, technically deep role for someone who can operate independently, define requirements in ambiguous environments, and drive complex hardware programs from architecture through commissioning. You will work across electrical, software, controls, and simulation teams to recreate the reactor's behavior in the lab and give engineers a robust platform for iterative testing and validation.

What You'll Do

• Build the hardware-in-the-loop test system from the ground up, including defining the architecture, selecting platforms such as NI PXI, dSPACE, Speedgoat, or similar, and bringing the complete electrical test environment online
• Recreate the reactor control system on a bench by simulating sensors, actuators, signals, and system inputs and outputs across the full reactor architecture
• Partner with software, controls, simulation, and electrical teams to ensure the test environment accurately reflects reactor behavior and supports reliable, iterative validation
• Define electrical and software integration requirements across power distribution, signal conditioning, sensor mapping, actuator interfaces, communications, and device simulation
• Own the electrical validation strategy, including test procedures, automation tooling, data acquisition, debugging methodologies, and engineering best practices supporting a major upcoming commercial deployment milestone

What We're Looking For

• 10+ years of experience in electrical engineering, with a focus on integration and test
• Experience building hardware-in-the-loop test systems from the ground up
• Experience with platforms such as NI PXI, dSPACE, Speedgoat, or similar
• Strong background in signal conditioning, sensor and actuator interfacing, and power distribution
• Comfortable operating independently and defining requirements in ambiguous, first-of-a-kind environments
• Experience developing test automation, data acquisition systems, and validation methodologies for complex hardware programs
• Comfortable operating in a highly regulated or safety-critical hardware environmentLocation: Los Angeles area, CA (5 days on-site)
• Full-time
