Muon Space, a LEO satellite constellation provider founded in 2021, seeks a Senior Reliability Engineer to serve as the technical lead of the reliability vertical within the Hardware Reliability & Test organization. This is a build-and-lead opportunity to unify reliability practices currently scattered across individual hardware teams, establishing standardized models, methods, and processes that ensure mission-critical constellation performance.
You will own how Muon predicts, measures, and improves hardware reliability across the organization. Key responsibilities include:
- Develop and evolve quantitative reliability models from component failure rates through system-level availability
- Build and standardize reliability methods across hardware teams: FMEA/FMECA, fault trees, and single-point-failure analysis
- Partner with domain experts to establish common part-level reliability standards, including derating guidelines, COTS screening philosophy, and radiation-tolerance approach
- Identify gaps in test coverage and reliability data; drive qualification and life-test strategies with test teams
- Close the loop with fleet data: use on-orbit performance and anomalies to refine models and guide design improvements
- Embed reliability into the hardware lifecycle by partnering with design teams on design reviews, worst-case analyses, and qualification planning
- Communicate reliability posture to leadership and customers; support proposals with reliability analyses
- Mentor engineers across teams on reliability methods, laying the foundation for a growing reliability function
The role reports to the Senior Manager of Hardware Reliability & Test and carries substantial growth potential, including a path into people management for the right candidate. This is a hybrid position requiring three days per week on-site in San Jose, CA.
REQUIREMENTS:
- 8+ years of engineering experience with complex, high-reliability hardware, including 5+ years in reliability engineering
- Strong command of reliability analysis methods: FMEA/FMECA, fault trees, statistical reliability modeling, and derating analysis
- Experience applying industry reliability standards (e.g., MIL-HDBK-217, ECSS, AEC-Q, or similar)
- Demonstrated ability to turn test and field data into failure-rate estimates and actionable design recommendations
- Statistical fluency: Weibull analysis, confidence bounds, accelerated life testing with supporting tools (Python, R, or dedicated reliability software)
- Proven ability to define processes and drive consistency across multiple engineering teams
- Excellent communication and presentation skills
- B.S. or higher in Electrical, Mechanical, Aerospace Engineering, or related field
NICE-TO-HAVE:
- Spacecraft or satellite reliability experience, including radiation effects on electronics
- On-orbit anomaly investigation or FRACAS experience
- Experience with reliability approaches for COTS-based space hardware
- Experience with reliability software tools (ReliaSoft, Relyence, or similar)
- Experience standing up new processes or functions within an engineering organization
- Technical leadership or mentoring experience
