Senior Systems Modeling Engineer, Beam Planning & Network Optimization Blue OriginSenior Systems Modeling Engineer, Beam Planning & Network OptimizationWashingtonAs a large-scale low Earth orbit constellation operating thousands of satellites across multiple orbital shells, TeraWave must solve resource assignment problems of extraordinary combinatorial complexity — from deciding which beams illuminate which ground cells at each moment in time, through routing data across a dynamic optical inter-satellite link mesh with thousands of nodes and time-varying topology, to assigning satellites to gateways and managing handovers as the constellation moves overhead. As part of this team, you will also contribute to the broader modelling of TeraWave's constellation performance — including its ability to maintain consistent customer service through progressive deployment phases, satellite failures, and orbital manoeuvres — bringing the network optimization perspective into system-level figures of merit and ensuring that resource assignment trades are evaluated in the context of their impact on end-to-end service delivery.
