Principal Electrical Engineer, Integration & Test
About The Position
Radiant is seeking a Principal Electrical Engineer to lead the electrical system architecture and test infrastructure for Kaleidos, Radiant's commercial microreactor unit targeted for deployment in 2028. You will own end-to-end electrical integration, from early architecture and requirements definition through hardware bring-up, testing, and commissioning, and serve as the technical authority, ensuring the electrical and validation systems are ready to support that milestone. 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.
Requirements
- BS in Electrical Engineering or related discipline from an accredited institution.
- 10+ years of progressive electrical engineering experience, including hands-on hardware design, integration, and test.
- Demonstrated experience setting technical direction, mentoring engineers, and driving programs with significant scope and ambiguity.
- Demonstrated ability to work under tight timelines and deliver a functional product that meets requirements.
- 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.
- Strong electrical and software debugging and root cause analysis skills.
- 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).
Nice To Haves
- MS or PhD in Electrical Engineering, or a related discipline.
- 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.
- Background in high-reliability, safety-critical, or regulated industry environments (aerospace, defense, nuclear, medical, or automotive)
Responsibilities
- Define and own electrical and software integration requirements spanning power distribution, signal conditioning, sensor mapping, actuator interfaces, and device simulation.
- 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.)
Benefits
- Substantial incentive stock plan for all full-time employees.
- 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans.
- Sponsored memberships for employees and their dependents.
- 100% top tier plan coverage + 50% for dependents.
- 100% top tier plan coverage, orthodontia extra, 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.
- Daily catered lunch. Free snacks and drinks.
- Flexible PTO policy. Remote workday allocation.
- Company and team-bonding events, happy hours and in-person camaraderie.
