Job summary

Radiant is seeking a Harness Design Engineer to design, build, and integrate electrical harnesses for a transportable nuclear microreactor program in El Segundo. You will collaborate with mechanical and electrical engineers to tackle system architecture, sensor selection, packaging, and end-to-end hardware development from CAD to test and validation.

The role requires hands-on experience with harnessing architectures, HV up to 1000 V, and manufacturing drawings, with on-site responsibilities and

Qualifications

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, or a closely related field from an accredited institution.
• 3+ Years of professional hands-on harness design or manufacturing experience.
• Strong understanding of harnessing architecture, grounding schemas, power requirements, and shielding.
• Strong understanding of electrical systems and the ability to interpret schematics.
• Proficiency with analog instrumentation including 4-20mA sensors, accelerometers, resolvers, RTDs, and thermocouples.
• Experience with Zuken E3 Cable, EPLAN, or similar harness design and schematic capture tools.
• Proficiency with inductive devices such as solenoid valves.
• Familiarity with Siemens NX or similar 3D CAD tools.
• Basic understanding of high-voltage systems up to 1000 volts.

Responsibilities

• Own the design of the harnessing system from concept to integration, and serve as the subject matter expert on the interconnection between electrical and hardware systems.
• Create harness drawings for manufacturing and act as the primary point of contact for the harness manufacturing team.
• Support the creation of the reactor electrical schematics using Zuken E3 Cable and maintain the pinout tables throughout the design cycle.
• Make decisions about conductor sizing, wire type, and shielding methods for low and high voltage using industry standards for guidance.
• Use an understanding of electrical failure mechanisms, including voltage drop, thermal effects, and interference, to identify and mitigate risks.
• Select materials, with support from the materials team, for harnessing in challenging environments across the reactor.
• Support technicians with harness integration on the reactor as the system owner.
• Work with the electrical team to commission the system and troubleshoot issues across the reactor.
• Provide nonconformance solutions throughout the build and integration phases of development to limit program delays and maximize system uptime.
