Job summary

Blue Origin seeks a rigorous space-safety analyst to develop, own, and maintain MMOD environment and impact risk models for spacecraft design and regulatory submissions. You will build demise and re-entry survivability models, and collaborate across propulsion, power, thermal, and GNC teams to translate outputs into actionable design requirements.

You will develop and maintain tools in MATLAB and Python, contribute to trade studies for constellation design, and support regulatory filings with

Qualifications

• Bachelor's degree in aerospace or related field.
• 5+ years in orbital debris analysis or related disciplines.
• Proficiency in MATLAB and/or Python for scientific computing.
• Knowledge of MMOD environment and debris models (e.g., ORDEM).
• Ability to document modeling methods and results for regulatory submission.
• Ability to work collaboratively in a fast-paced, dynamic environment.

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 pressurised 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
