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
• 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

Benefits

• 100% health, dental, and vision coverage for employees; 50% coverage for dependents (Concierge Medical offered through One Medical where available)
• Parental leave for primary and secondary caregivers
• Generous time off policy
• 401(k) plan through Betterment and equity management through Carta
• Fully stocked kitchen at our HQ and we cater lunch 3 days per week
• Dog-friendly office

• 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
• B.S. in Computer Science, Electrical/Computer Engineering, or a related technical field
• Excellent communication and presentation skills
• Expert-level Python, including designing frameworks or libraries adopted by other engineering teams
• Experience with databases and building tooling and user interfaces
• Experience developing software that controls and tests physical hardware, including writing drivers for test instruments (e.g., VISA/SCPI, serial, CAN, or Ethernet-based)
• Working knowledge of electronics and lab test equipment; comfortable debugging at the bench
• 8+ years of software engineering experience, with demonstrated technical leadership of complex, multi-engineer projects
• Excited to work in a fast-paced environment with new challenges each week
• We encourage you to apply, even if you don’t check all the boxes, and we look forward to reviewing your application!

• Experience with reading & modifying embedded C/C++ applications
• Experience with results/time-series databases and dashboarding tools (e.g., SQL, InfluxDB, Grafana)
• Experience testing spacecraft, launch vehicles, or other aerospace hardware
• Experience with hardware-in-the-loop simulation or production/acceptance test systems
• Familiarity with pytest or similar frameworks as a foundation for hardware test
