Hardware Test Engineer II, Testbeds & EGSE

Muon Space•San Jose, CA

1d•$157,000 - $182,000•Onsite

About The Position

Muon seeks a Hardware Test Engineer 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. In this role, you will lead the design of future testbed infrastructure and next-generation EGSE, while also being hands-on in the build and bring-up of current testbeds. This role is at the crossroads of disciplines, welcoming engineers with electrical, embedded software, mechanical, or industrial controls backgrounds. You will work directly with the electrical missions team to define testbed parallels of mission flight hardware, seeing your designs go from concept to daily use across the company. Due to the hands-on nature of this role, it requires onsite work at our San Jose location 5x days a week.

Requirements

5+ years of hands-on experience with complex electromechanical systems, including 2+ years in test, testbed, or test-infrastructure development
Background in electrical engineering, embedded software, mechanical engineering, or industrial controls
Experience designing hardware — electrical, mechanical, or integrated systems — that others build and use
Ability to read and work from electrical schematics, block diagrams, and production drawings
Strong hands-on debugging skills across hardware and software interfaces, with standard test equipment (multimeters, oscilloscopes)
Scripting or programming ability (Python, Bash, or similar)
Understanding of electronics fundamentals and common communication interfaces (e.g., UART, SPI, I2C, CAN, Ethernet)
Excellent communication and teamwork skills, comfortable in a fast-paced environment
B.S. in an engineering discipline or equivalent hands-on experience
Comfort in a Linux development environment

Nice To Haves

Experience with HITL testbeds, lab automation, or large-scale test infrastructure
Electrical CAD experience (Altium preferred) or harness design tools
Mechanical CAD experience (SolidWorks preferred) for rack and fixture design
Experience with industrial automation or rack-based electronics, networking, and power distribution
Aerospace or other high-reliability industry experience

Responsibilities

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
