RF Test Engineer II, Testbeds & EGSE

Muon Space•San Jose, CA

1d•$168,000 - $186,000•Onsite

About The Position

Muon seeks an RF Test Engineer to join their Testbeds & EGSE team. This team is responsible for building the Hardware-In-The-Loop (HITL) testbeds for all Muon missions and the electrical ground support equipment (EGSE) used to interface with satellites during assembly, integration, and test. The role involves leading the design of future testbed infrastructure and next-generation EGSE, while also being hands-on in the build and bring-up of current testbeds. The position requires collaboration across disciplines and with the electrical missions team to define testbed parallels of flight hardware, seeing designs from concept to daily use. Due to the hands-on nature, this role requires onsite work 5 days a week at the San Jose location.

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
Experience using RF testing equipment
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
