About the roleMuon seeks a Senior Software Engineer to join our Hardware Reliability & Test organization as the technical lead for our hardware test frameworks - the software, standards, results databases, and tooling used to test Muon hardware from module level through fully assembled spacecraft. The ideal candidate is a hands-on engineer who bridges hardware and software: equally comfortable architecting clean Python frameworks and debugging test instruments at the bench.
This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
Responsibilities- Serve as the technical lead for Muon's hardware test frameworks: own architecture, standards, and the technical roadmap
- Design and build Python-based test frameworks and tooling used from module-level through fully assembled spacecraft testing
- Write drivers and abstractions for test instruments and ground support equipment (power supplies, DAQs, oscilloscopes, environmental chambers, RF test equipment)
- Architect test results databases and user interfaces, selecting the right technologies for Muon's scale
- Build standard, shared spacecraft-level tests that can be tailored per mission
- Partner with subsystem, bus, and test teams to drive framework adoption, supporting and training users
- Integrate test frameworks with CI/CD and hardware-in-the-loop infrastructure for automated regression testing
- Mentor engineers and set the bar for code quality across hardware test software
Qualifications- Experience developing software that controls and tests physical hardware, including writing drivers for test instruments (e.g., VISA/SCPI, serial, CAN, or Ethernet-based)
- B.S. in Computer Science, Electrical/Computer Engineering, or a related technical field
- 8+ years of software engineering experience, with demonstrated technical leadership of complex, multi-engineer projects
- Expert-level Python, including designing frameworks or libraries adopted by other engineering teams
- Working knowledge of electronics and lab test equipment; comfortable debugging at the bench
- Experience with databases and building tooling and user interfaces
- Excellent communication and presentation skills
- Excited to work in a fast-paced environment with new challenges each week
Nice-to-have Skills- Experience testing spacecraft, launch vehicles, or other aerospace hardware
- Experience with reading & modifying embedded C/C++ applications
- Experience with hardware-in-the-loop simulation or production/acceptance test systems
- Familiarity with pytest or similar frameworks as a foundation for hardware test
- Experience with results/time-series databases and dashboarding tools (e.g., SQL, InfluxDB, Grafana)
SalaryThe salary range for this role is $184,000 - $208,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
