Sr Systems Modelling Engineer - Space Safety & sustainability

Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

As a member of the Integrated System Modelling team within the Tera Wave Chief Systems Architecture office, you will develop, own, and maintain the analytical models that underpin Tera Wave's space safety and sustainability posture. Your models will directly inform architecture decisions on debris mitigation, collision avoidance, post-mission disposal, and demise compliance — translating regulatory requirements and physical environments into quantitative predictions that drive design.

This is a hands-on modelling and analysis role. You will build and maintain the integrated models — in MATLAB, Python, and purpose-built tools — that produce the quantitative basis for Tera Wave's space safety commitments. Your work will feed directly into regulatory filings, architecture trade studies, and design requirements across spacecraft, propulsion, power, and operations teams. You will work within the Integrated System Model framework alongside engineers modelling power, communications, and orbital performance, ensuring that space safety analysis is tightly coupled to the broader system picture rather than developed in isolation.

As part of this team, you will also contribute to the broader modelling of Tera Wave’s constellation performance — including its ability to maintain consistent customer service through progressive deployment phases, satellite failures, and orbital manoeuvres — bringing the space environment perspective into system-level figures of merit and ensuring that safety and sustainability trades are evaluated in the context of their impact on network capability.

Successful candidates will bring strong analytical foundations in orbital debris environment modelling, spacecraft survivability and demise analysis, and collision probability assessment, combined with the software development skills to build maintainable, validated, and accessible models that the broader team can use and trust.

If you share our passion for leaving space better than we found it, thrive in a dynamic startup environment, excel on integrated cross-functional teams of individuals, are experienced and skilled in several relevant areas listed below, continuously seek out opportunities to learn and improve, and do not allow title or job description to limit the depth or breadth of your contributions, then we would love to hear from you.
