Technician II, Testbeds & EGSE

Muon Space•San Jose, CA

3d•Onsite

About The Position

Muon seeks a Technician to join our Testbeds & EGSE team. This team builds the Hardware-In-The-Loop (HITL) testbeds for every Muon mission and the electrical ground support equipment (EGSE) used to interface with satellites during assembly, integration, and test. The role involves assembling testbed racks and EGSE units, fabricating harnesses, and maintaining critical infrastructure that software and hardware teams rely on. The ideal candidate is a meticulous builder and troubleshooter, comfortable working from drawings and block diagrams, maintaining organized and documented hardware, and taking pride in reliable infrastructure. As much of this hardware is first-of-its-kind, the role often requires working without step-by-step procedures, necessitating comfort in seeking information and directly engaging with engineers. Due to the hands-on nature of this role, it requires onsite work at our San Jose location five days a week.

Requirements

5+ years of hands-on experience assembling and maintaining electrical or electromechanical hardware
Skilled in harness fabrication: connectorization, pinning, crimping, and continuity testing
Experience with PCBA assembly and rework (surface mount and through-hole)
Competence with basic electrical test tools (multimeter at minimum) for troubleshooting
Comfort in a Linux heavy development environment
Ability to work from drawings, schematics, and block diagrams with minimal supervision
Self-sufficient when documentation is thin: comfortable seeking out information, asking engineers directly, and exercising judgment rather than waiting for a formal procedure
Careful documentation habits and an organized approach to lab and inventory management
Excellent communication and teamwork skills
Comfortable in a fast-paced environment where priorities shift week to week

Nice To Haves

Experience supporting test labs, HITL facilities, or similar engineering infrastructure
IPC-A-620 / J-STD-001 or similar certifications for soldering and cable assembly
Familiarity with Linux command line, Bash, or Python basics
Experience with rack-based electronics, networking, or power distribution equipment
Aerospace, automotive, or other high-reliability industry experience

Responsibilities

Assemble HITL testbed hardware: racks, avionics modules, wiring, and interconnects, working from drawings, block diagrams, and engineering direction
Assemble and maintain spacecraft test equipment (EGSE) used to power, command, and monitor satellites during integration and test
Fabricate, modify, and repair cable harnesses, including connectorization, pinning, and continuity checkout
Perform PCBA assembly and rework (surface mount and through-hole soldering)
Maintain testbed infrastructure and support resources — power, network, and lab equipment — and respond quickly when systems go down
Troubleshoot electrical issues with standard test tools (multimeters, oscilloscopes) alongside engineers
Perform light mechanical fabrication: drilling, tapping, rack fit-up, and proper torquing of fasteners
Track testbed and EGSE inventory, and document builds, changes, and repairs with logs and procedure redlines
