Space Systems Modeling and Analysis Engineer

We are seeking a Space Systems Modeling and Analysis Engineer to develop and deploy high-fidelity computational models of multi-orbit space architectures supporting satellite communications (SATCOM) navigation warfare (NAVWAR) space-based sensing and targeting (SBST) and missile warning and tracking (MWT) this role you will build fast parallelizable simulations of proliferated constellations across LEO MEO and GEO. You will model space-to-space crosslinks space-based RF and EO/IR sensors as well as ground segment architectures. You will perform constellation-level operational availability analysis that goes beyond link coverage to account for real-world operational impacts such as downtime due to routine on-orbit maintenance ground gateway availability and disturbances from both ground- and space-based threats. You will support trade studies on constellation design link budgets timing architectures for alternative positioning/navigation/timing (Alt-PNT) frameworks and sensor coverage geometries. Your work will directly inform architecture decisions that ensure resilient space systems in contested and degraded environments.

Key job responsibilities
- Develop validate and maintain high-fidelity models of multi-orbit constellations (pLEO MEO GEO) for SATCOM NAVWAR SBST and MWT mission areas
- Design and execute large-scale parallelizable simulations to evaluate constellation performance coverage and resilience under nominal and degraded conditions
- Perform trade studies and sensitivity analyses on constellation design parameters sensor geometries and network topologies
- Model ground segment architectures including radar systems ground entry points and ground-based command and control infrastructure
- Model space-based threats including maneuverable satellites counter-space systems and electromagnetic warfare effects on space architectures
- Model Alt-PNT frameworks including timing budget analysis and navigation warfare scenarios
- Analyze Space Data Network (SDN) architectures including space-to-space crosslinks exchange points and network service orchestration
- Develop sensor performance models for multi-phenomenology detection (infrared radar) across missile warning and moving target indication missions
- Support architecture decisions by quantifying system resilience capacity and performance under adversarial conditions
- Produce technical documentation trade study reports and briefings for engineering and program leadership
- Collaborate with systems engineers mission architects and government stakeholders to translate operational requirements into simulation parameters
