ACS / GNC Engineer (Senior / Principal Levels)

Responsibilities

• Lead the analysis, design, and development of spacecraft attitude determination and control algorithms, simulations, and system models.


• Own ACS/GNC requirement decomposition, allocation, verification planning, and performance assessment from mission-level requirements through subsystem implementation.


• Lead trade studies for sensors, actuators, control architectures, estimation approaches, and mission-specific ACS/GNC concepts of operation.


• Define and maintain high-fidelity simulation environments to support design, integration, test, and mission operations.


• Lead software-in-the-loop, processor-in-the-loop, hardware-in-the-loop, and other integrated verification activities for ACS/GNC functionality and performance.


• Support spacecraft integration, test, commissioning, mission operations, and anomaly investigation using telemetry and flight data.


• Serve as the ACS/GNC technical interface to systems engineering, flight software, avionics, mechanical, thermal, manufacturing, and mission operations teams to ensure mission objectives are understood and supported by product design.


• Prepare for and present at internal and customer design reviews as an ACS/GNC subject matter expert.


• Provide technical direction and mentorship to junior engineers and contribute to the development of ACS team processes, standards, and best practices.


• Work with ACS hardware suppliers and internal supply chain teams to evaluate, select, procure, and integrate hardware needed to meet technical and programmatic objectives.

Qualifications

• Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, physics, or related technical field required; Master’s degree or PhD preferred.


• 6+ years of experience in spacecraft GNC/ACS development (8+ years preferred); equivalent advanced degree plus directly relevant experience may be considered.


• Strong background in spacecraft attitude dynamics, control theory, estimation, and system modeling (Salary based on experience).


• Demonstrated experience developing and analyzing ADCS/GNC algorithms for spacecraft applications.


• Experience with requirements development, verification, and performance validation for flight systems.


• Experience with MATLAB and Simulink; experience with Python, C/C++, or flight-software-adjacent development preferred.


• Experience supporting integrated test campaigns, mission operations, and anomaly resolution using telemetry and flight data.


• Demonstrated ability to lead technical work across multiple disciplines and mentor less-experienced engineers.


• Strong analytical, problem-solving, written, verbal, and presentation skills.


• Collaborative and effective in team environments.


• U.S. citizenship required.


• Must be able to obtain and maintain a U.S. security clearance.


• Willingness to work full-time in our Greenwood Village, CO office; this position does not support remote or hybrid work.
