Job description

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.We are seeking a Satellite Simulation and Test Software Engineer IV/Sr to design, develop, and verify simulation environments and models for testing TeraWave’s satellite flight software subsystem. This role will be instrumental in software validation to support the expansion of TeraWave into a 5,408-vehicle constellation. The ideal candidate is a hands-on engineer who can think independently and work in collaboration with subject matter experts to build a practical, scalable, flexible simulation environment.
