Muon Space, an end-to-end space systems provider designing and operating LEO satellite constellations, seeks an RF Test Engineer I to join the Testbeds & EGSE team. This team builds Hardware-In-The-Loop (HITL) testbeds and electrical ground support equipment (EGSE) that enable satellite assembly, integration, and testing.
You will work hands-on with senior engineers to assemble and bring up testbeds for each mission, design next-generation EGSE, and contribute to the infrastructure that powers Muon's satellite operations. The role sits at the intersection of multiple disciplines—electrical, embedded software, mechanical, and controls engineering—and values curiosity about how complete systems work alongside hands-on instinct and eagerness to learn.
Key responsibilities include:
- Building, integrating, and bringing up HITL testbed hardware (racks, avionics modules, harnessing, external interfaces) for each mission
- Assisting in the design of testbed hardware and next-generation EGSE used to power, command, and monitor satellites during integration and test
- Translating flight hardware designs (block diagrams, schematics, drawings) into mission-specific testbed configurations in collaboration with the electrical missions team
- Debugging hardware and interface issues across testbeds alongside electrical, software, and systems engineers
- Maintaining testbed support infrastructure (power, network, lab resources) and responding to system outages
- Creating and maintaining documentation including testbed architecture diagrams, build records, and checkout procedures
- Coordinating with supply chain and production teams on testbed inventory and module builds
This role requires 5 days per week onsite at the San Jose location due to its hands-on nature.
REQUIREMENTS:
- 2+ years of hands-on experience building, testing, or debugging hardware in complex electromechanical systems (internships and substantial project work considered)
- Background in electrical engineering, embedded software, mechanical engineering, or industrial controls
- Hands-on hardware skills: assembly, wiring, and basic troubleshooting with tools like multimeters and oscilloscopes
- Understanding of electronics fundamentals and common communication interfaces (UART, SPI, I2C, CAN, Ethernet)
- Basic scripting or programming ability (Python or Bash)
- Strong problem-solving skills and hands-on approach to engineering challenges
- Excellent communication and teamwork skills with desire to learn in fast-paced environment
- B.S. in an engineering discipline or equivalent hands-on experience
- Comfort in a Linux-heavy development environment
NICE-TO-HAVE SKILLS:
- Experience with HITL testbeds, test labs, or lab automation
- Experience using RF testing equipment
- Harness design/assembly experience or familiarity with electrical CAD (Altium) or mechanical CAD (SolidWorks)
- PCBA assembly and rework experience
- Experience with industrial automation or rack-based electronics and networking
- Aerospace or other high-reliability industry experience
