Mission Simulation Engineer III

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 TeraWave, 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 TeraWave integrated system modelling team, you will play a foundational role in the development of an integrated mission simulation model that captures the full-system behavior of the TeraWave satellite constellation. TeraWave is a satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This network will service tens of thousands of enterprise, data center, and government users who require reliable connectivity for critical operations. The integrated mission simulation model you help build will serve as a critical program-wide tool used to analyze, optimize, and validate constellation performance from early design through deployment and operations.

As a Mission Simulation Engineer III, you will take a lead role in implementing and continuously improving an integrated simulation framework spanning orbital mechanics, spacecraft power modeling, payload beam assignments, traffic routing, and payload utilization. You will collaborate closely with fleet management, mission operations, payload, power, network, and GNC engineering teams to ensure each simulation domain accurately reflects flight system behavior. A key focus of this role will be developing analysis and optimization capabilities to extract maximum performance and coverage value from the constellation while minimizing system cost, as well as modeling constellation deployment phases and build-up timelines that inform program planning and architecture decisions. The simulation scope spans both RF and optical link domains, including inter-satellite links and ground-to-space links, requiring candidates to be comfortable reasoning across both link types. Successful candidates will bring deep technical expertise in astrodynamics and spacecraft systems engineering, paired with strong software development skills to build scalable, high-fidelity simulation environments. A preferred candidate will have experience working across satellite bus and payload disciplines with a demonstrated ability to integrate physics-based and performance-based models into a coherent, maintainable simulation framework that directly informs constellation design decisions.
