Responsibilities

Architect solutions for space mission objectives related to space domain awareness and RPOD, focusing on autonomy in both hardware and software.
Evaluate and select appropriate techniques such as machine learning, physics-informed solutions, stochastic methods, and Kalman Filters.
Assist in proposal capture efforts with feasibility analysis and engage with private/public partners, Department of Defense, Other Government Agencies, and commercial partnerships.
Develop architecture, lead trade studies, and lead the GNC team from conceptualization to flight for RPOD missions.
Design algorithms, simulations, and tools for orbit determination, state estimation, and uncertainty propagation to support SDA efforts.
Analyze and source datasets for training and validation of algorithm performance.
Build and test modeling and simulation tools for orbital/cislunar dynamics, sensor modeling, and visualization.
Perform six-degree-of-freedom modeling, simulation, and validation of spacecraft dynamics, sensors, and algorithms, including for RPOD missions.
Collaborate with software and GNC teams to implement algorithms in flight software.
Support hardware-in-the-loop testing for integrated system validation.
Design concepts of operations (CONOPS) that balance thermal, power, momentum, and communications for spacecraft missions.
Provide mission operations training and support.
