Hardware Test Engineer; Testbeds & EGSE Job San Jose area,California USA,Engineering

Position: Hardware Test Engineer (Testbeds & EGSE)

Muon seeks a Hardware Test Engineer to join our Testbeds & EGSE team — the group that builds the Hardware-In-The-Loop (HITL) testbeds behind every Muon mission and the electrical ground support equipment (EGSE) used to interface with our satellites during assembly, integration, and test
In this role you’ll lead the design of our future testbed infrastructure and next generation of EGSE, while staying hands‑on in the build and bring‑up of the testbeds our missions depend on today
This team sits at the crossroads of disciplines, and so can you: engineers with electrical, embedded software, mechanical, or industrial controls backgrounds all thrive here
You’ll work directly with the electrical missions team to define each testbed’s parallel of the mission’s flight hardware, and see your designs go from concept to daily use across the company
Lead the design of future HITL testbed infrastructure: architecture, form factor, non‑satellite hardware, and external interfaces
Lead the design of next‑generation EGSE used to power, command, and monitor satellites during integration and test
Work with the electrical missions team to define each testbed’s parallel of the mission’s flight hardware, translating block diagrams, schematics, and drawings into testbed designs
Build, integrate, and bring up testbed hardware alongside the team, and support the fleet in daily operation
Generate and maintain testbed architecture diagrams, interface definitions, and design documentation
Debug hardware and interface issues across testbeds to root cause, working with electrical, software, and systems engineers
Coordinate with supply chain, production, and facilities teams on testbed inventory, module builds, and support resources (power, network)
Guide junior engineers and technicians on the team, and drive testbed designs that scale with an increasingly capable satellite fleet
