Reliability Engineer

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly. Who We're Looking For We are seeking a Reliability Engineer to ensure the reliability, safety, and mission assurance of our next-generation spacecraft and supporting systems. In this role, you will perform reliability analyses, influence system architecture and hardware design, support environmental testing and failure investigations, and help establish the processes that ensure mission success throughout the product lifecycle. The ideal candidate thrives in a fast-paced environment, enjoys solving complex technical challenges, and is passionate about building next-generation space systems that support mission success. Where You'll Make an Impact Perform functional and interface Failure Mode, Effects, and Criticality Analyses (FMEA/FMECA) at the part, assembly, and system levels, and maintain the Critical Items List (CIL). Develop Fault Tree Analyses (FTA), Reliability Block Diagrams (RBD), and reliability predictions including MTBF and MTTF to support design trades, redundancy decisions, and sparing strategies. Apply physics-of-failure methodologies, Weibull analysis, accelerated life testing, and probabilistic risk assessment (PRA) to evaluate mission-critical hardware. Support EEE parts reliability through component selection and derating, parts stress analysis, worst-case analysis, and radiation effects screening in accordance with EEE-INST-002. Monitor GIDEP alerts and supplier advisories, tracking limited-life and limited-shelf-life components throughout the production lifecycle. Partner with design and systems engineering teams to integrate reliability requirements into spacecraft architecture, supplier selection, and manufacturing processes early in development. Provide actionable reliability analyses that influence redundancy, design margins, and component selection while maintaining documentation for technical reviews and audits. Support environmental qualification, life testing, and verification activities by reviewing test plans, evaluating results, and assessing reliability impacts. Tailor reliability activities to mission risk classifications while maintaining rigorous standards for safety-critical and range safety systems. Help develop and continuously improve Quantum Space's reliability engineering processes, procedures, analysis templates, and requirements within our AS9100 Rev D Quality Management System. What It Takes Bachelor's degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Systems Engineering, or a related engineering discipline. Approximately 5+ years of reliability, mission assurance, or closely related engineering experience supporting flight hardware or similarly high-reliability systems; senior…
