Probabilistic Risk Assessment Analyst-Human Spaceflight

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Probabilistic Risk Assessment Analyst – Human Spaceflight based in the United States. In this role, you will contribute to the safety and reliability of advanced human spaceflight and commercial launch systems through rigorous, data-driven risk analysis. You will develop and quantify probabilistic risk assessment (PRA) models to evaluate crew safety, mission success, and public safety risks across crewed spacecraft and launch vehicles. Working alongside multidisciplinary engineering, systems safety, and reliability teams, you will transform complex technical data into actionable insights that support critical engineering and operational decisions. You will also contribute to regulatory compliance and FAA launch licensing activities, helping ensure that flight safety analyses meet demanding industry standards. This position offers the opportunity to influence high-profile aerospace programs while collaborating with leading technical stakeholders in a mission-driven environment. Well-qualified remote candidates are welcome, with hybrid opportunities preferred for professionals located near Houston or Denver. Accountabilities - Develop and quantify risk models: Independently build, maintain, and refine probabilistic risk assessment models for human spaceflight and launch vehicle systems. Apply fault trees, event trees, cut-set analysis, and related methodologies to evaluate failure scenarios, common-cause failures, and key risk contributors. - Assess crew and mission safety: Conduct integrated quantitative risk assessments covering spacecraft and launch vehicle systems, abort scenarios, ground and flight operations, and crew-related hazards.

Evaluate Loss of Crew (LOC), Loss of Mission (LOM), and public safety risk metrics. - Perform reliability and uncertainty analyses: Collect and analyze reliability and failure data, incorporate Human Reliability Analysis (HRA) where applicable, and quantify epistemic and aleatory uncertainties to strengthen risk-informed decision-making. - Support regulatory compliance and launch licensing: Contribute to FAA Part 450 flight safety analyses and launch license applications, including expected casualty, probability of casualty, conditional expected casualty, probability-of-failure, debris, and other relevant risk assessments. - Apply aerospace safety standards: Ensure analytical methods and deliverables align with applicable NASA probabilistic risk assessment guidance, human-rating requirements, commercial spaceflight regulations, and range safety practices. - Collaborate with engineering stakeholders: Work closely with spacecraft, launch vehicle, systems engineering, safety, and reliability teams to gather design information, identify failure modes, validate assumptions, and incorporate operational data into risk models. - Communicate technical findings: Present risk drivers, sensitivity analyses, model results, and recommendations to customers, engineering teams, management, and other stakeholders to support informed technical decisions. - Prepare technical documentation: Develop clear, traceable PRA reports, model documentation, uncertainty assessments, and risk summaries. Integrate findings with hazard analyses, FMEA/FMECA, reliability studies, and certification activities. - Manage multiple technical engagements: Lead or execute analytical activities across multiple customer programs, maintaining technical rigor, accountability, and consistent delivery with minimal day-to-day supervision. Requirements - Education: Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Systems Engineering, Electrical Engineering, Mathematics, Statistics, or a related technical discipline. A master's degree is preferred.
