Principal Guidance, Navigation, and Control (GNC) Engineer
Highlights:
Location: Broomfield, CO
Employment Type: Direct-hire
Compensation: BOE
Position Description:
Our client's technology hinges on flawless execution of rendezvous, proximity operations and docking (RPOD) and stands at the intersection of Space Domain Awareness (SDA), robotics, and in-space upgrades. Complex algorithms are essential to unlocking this vision. This is the domain of GNC Engineers. You’ll primarily focus on the design, build, test, analysis and in orbit operation of the GNC system central to our rendezvous and proximity operations spacecraft and Space Domain Awareness (SDA) products.
If you have a background expertise in a relevant domain such as orbital mechanics, optimal control, spacecraft systems design, sensor fusion and navigation, and/or software development and you’re excited about making a big impact while leaning into collaboration—surrounded by Flagstaff’s Ponderosa pines or the Denver Rockies—we’d love to hear from you!
Key Responsibilities:
Architecture and Investigation
Architect solutions necessary to accomplish space mission objectives around space domain awareness and RPOD with an emphasis on autonomy, from both a hardware and software perspective.Evaluate and select appropriate techniques to achieve mission such as machine learning methods, physics-informed solutions, stochastic methods, Kalman Filters, etc.Assist in proposal capture efforts with feasibility analysis and engage with private/public partners, Department of Defense, Other Government Agencies, and other commercial partnerships.
Architecture Design
Develop architecture, lead trade studies and lead GNC team from conceptualization to flight for RPOD missionsDesign algorithms, simulations, and tools for orbit determination, state estimation, uncertainty propagation to support SDA effortsAnalyze and source datasets for training and validation or algorithm performance.Build and test modeling and simulation tools for orbital/cislunar dynamics, sensor modeling, and visualization.Six degree of freedom modeling, simulation and validation of space craft dynamics, sensors and algorithms, including for RPOD missions.
Implementation
Collaborate with the software and GNC teams to implement algorithm in flight software.Heavily 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.
