The ideal candidate will have a strong background in systems engineering, experience with space-based communication systems, and hands-on Python development skills for modeling and simulation. In this position, you will help develop and maintain Python simulations and other analysis tools used to model how our communications hardware functions, evaluate SATCOM constellation performance, support link budgets and system trade studies, and inform requirements development, concept of operations (CONOPS), verification planning, and risk assessment. You will work across multidiscipline engineering teams, contribute to technical decision-making, and support program execution with clear analysis, modeling results, and practical engineering judgment.
