Job summary

Blue Origin is seeking an experienced space safety analyst to develop and maintain MMOD environments, collision probability tools, and debris mitigation assessments. You will work across spacecraft subsystems to ensure regulatory readiness and design-for-demise considerations.

You will build validated analysis pipelines in MATLAB/Python, contribute to safety demonstrations for regulatory submissions, and collaborate with cross‑functional teams across the constellation design and operations

Qualifications

• Bachelor's degree in aerospace engineering, astrodynamics, physics, mechanical engineering, or equivalent technical field.
• 5+ years of experience in orbital debris analysis, spacecraft survivability, collision avoidance, or closely related technical disciplines.
• Proficiency in MATLAB and/or Python for scientific computing.
• Knowledge of the MMOD environment, including debris population models (e.g., ORDEM).
• Familiarity with re-entry demise analysis methodology and tools (e.g., DAS or equivalent).
• Knowledge of conjunction assessment and collision probability methods, including covariance-based Pc estimation and miss distance statistics.

Responsibilities

• Develop, own, and maintain MMOD environment and impact risk models, including flux characterization, impact probability estimation, and shielding effectiveness assessment to inform vehicle design requirements.
• Develop and maintain demise and re-entry survivability models, including aerothermal breakup analysis, ground casualty risk estimation, and compliance assessment against demisability requirements.
• Develop collision probability models and conjunction assessment analysis tools at full constellation scale.
• Build and maintain validated, version-controlled, and documented analytical tools in MATLAB and/or Python, ensuring reproducibility of results and enabling rapid trade studies as the design evolves.
• Perform MMOD-driven failure mode analysis for critical spacecraft systems—particularly batteries, propellant tanks, and pressurized systems—to inform shielding, placement, and passivation design decisions.
• Support adherence to orbital debris mitigation plans by providing the underlying analytical results, model descriptions, and compliance assessments required for regulatory submission.
• Integrate space safety models within the broader Integrated System Model, ensuring consistency with system-level orbital mechanics, power, thermal, and mission timeline models.
• Perform trade studies quantifying the space safety implications of constellation design choices, including altitude and inclination, spacecraft geometry and materials, disposal strategies, and operational concepts.
• Develop and maintain space traffic density and long-term debris environment models, including assessment of the constellation's own contribution to the debris environment.
• Collaborate with spacecraft, propulsion, power, thermal, and GNC teams to translate model outputs into actionable design requirements.
