Job summary

Radiant Industries in El Segundo, CA seeks a Principal Electrical Engineer to lead the electrical system architecture and test infrastructure for Kaleidos, our 1 MW portable microreactor, targeting 2028 deployment.

You will own end-to-end electrical integration from architecture to hardware bring-up, testing, and commissioning, and guide Hardware-in-the-Loop systems and broader test environments. 100% onsite.

Qualifications

• BS in Electrical Engineering from an accredited institution.
• 8+ years of progressive electrical engineering experience, including hands-on hardware design, integration, and test.
• 5+ years developing hardware-in-the-loop (HIL) systems, including signal conditioning, DAQ/IO interfaces, plant model integration, and embedded controls validation.
• Demonstrated experience setting technical direction, mentoring engineers, and driving programs with significant scope and ambiguity.
• Proven ability to deliver a functional product that meets requirements under tight timelines.
• Experience with DAQ and test systems (NI PXI, dSPACE, Speedgoat, or similar), including test execution and validation frameworks.
• Proficiency with test software and scripting environments (LabVIEW, TestStand) and at least one programming language (Python, C++, C#).
• Strong electrical and software debugging and root cause analysis skills.
• Experience working cross-functionally with software, mechanical, and systems engineering teams.
• Background in high-reliability, safety-critical, or regulated environments (aerospace, defense, nuclear, medical, or automotive).

Responsibilities

• Build the HIL platform from the ground up: plant simulation, real hardware in the loop, and the test environment Kaleidos ultimately ships from.
• Own the design, build, and maintenance of electrical test infrastructure, establishing it as a foundational asset for validating the commercial unit ahead of 2028.
• Define and own electrical and software integration requirements across power distribution, signal conditioning, sensor mapping, actuator interfaces, and device simulation.
• Own the communication layer between hardware, control systems, and software protocol selection, timing, and fault behavior at the boundaries.
• Define and drive the electrical validation strategy, developing the test procedures and methodologies the program depends on.
• Own schedule, budget, and vendor management for electrical hardware and integration activities.
• Drive automation and tooling improvements, with real influence over how the team tests.
• Lead design reviews and carry technical decisions to stakeholders across electrical integration, embedded, software, and controls.
