## Description

Radiant is seeking a Harness Design Engineer to support the design, build, and integration of electrical wire harnesses in a fast-paced startup environment. You'll work alongside experienced mechanical and electrical engineers to solve challenging problems in system architecture, sensor/actuator selection, packaging, and system integration for advanced hardware. This role offers hands-on exposure to end-to-end hardware development from CAD and analysis through build, test, and validation., * 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.
