About the role

The ideal candidate brings deep electrical engineering expertise, strong systems-level thinking, and a track record of leading complex hardware programs from concept to deployment.
You are equally comfortable making architecture decisions independently and collaborating across mechanical, software, and systems engineering teams.

Own and build out the electrical test infrastructure for Kaleidos, and establish the test environment as a foundational asset to validate the commercial unit ahead of the 2028 deployment target.
Establish and maintain communication between hardware, control systems, and software interfaces.
Define and drive electrical validation strategy; develop test procedures, methodologies, and best practices.
Manage schedule, budget, and vendor management for electrical hardware and integration activities.
Optimize test and validation processes; develop tooling and automation to improve efficiency.
Support electrical integration across multiple critical systems and subsystems.
Lead design reviews and effectively communicate technical decisions to cross-functional stakeholders. (Electrical integration, embedded, software, controls.)
Radiant is an El Segundo, CA-based startup building the world's first mass-produced, portable nuclear microreactors.
Radiant's unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials.
Define and own electrical and software integration requirements spanning power distribution, signal conditioning, sensor mapping, actuator interfaces, and device simulation.

Experience with DAQ and test systems (e.g., NI PXI, dSpace, Speedgoat, or similar platforms).
Proficiency with software and scripting environments (e.g., LabVIEW, TestStand)
Proficiency with data acquisition systems, test execution, and validation frameworks.
Experience working cross-functionally with software, mechanical, and systems engineering teams.
Proficiency in at least one scripting or programming language (Python, C++, C#, or similar).
Familiarity with real-time simulation systems and/or FPGA-based hardware.
Experience with controls fundamentals and software testing processes.
Hands-on experience with trace capture, data acquisition, and analysis tools.
MS or PhD in Electrical Engineering, or a related discipline.
Background in high-reliability, safety-critical, or regulated industry environments (aerospace, defense, nuclear, medical, or automotive)

100% top tier plan coverage + 50% for dependents.
Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits.
8-weeks of paid parental leave for all parents.
Additional paid pregnancy leave for CA employees.
