Senior Software Engineer, Hardware Test

Muon 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.

- 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

- 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

- Excited to work in a fast-paced environment with new challenges each week

- 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)

The 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.
