You’ll work alongside experienced engineers solving real flight problems, not just theoretical models.If you’ve built simulations, worked with spacecraft dynamics, or touched control systems in a meaningful way — this is where you level up.What You’ll DoGNC Engineering (Core – ~50%)Contribute to the design and implementation of spacecraft GNC systems across new and existing platformsWork across sensors, actuators, control algorithms, and flight software integrationSupport requirements development and flow-down across subsystem componentsParticipate in design activities spanning spacecraft, payloads, and integration environmentsDrive reuse of existing system architectures while identifying where new design is requiredCollaborate across multidisciplinary teams (systems, software, hardware, integration)Simulation & Modeling (Major Focus – ~40%)Develop and maintain high-fidelity simulation environments for spacecraft performance analysisBuild models integrating GNC algorithms, sensors, actuators, and flight softwarePerform Monte Carlo analysis, covariance analysis, and closed-loop performance validationSupport mission trade studies and system-level performance verificationAutomate simulation workflows to improve iteration speed and engineering throughputDocument models, assumptions, and validation results for design reviewsAdditional Contributions (~10%)Support product line evolution and design standardization effortsAssist in anomaly resolution, troubleshooting, and system improvementsIdentify opportunities for cost efficiency and design optimizationWhat You BringRequiredBachelor’s degree in Engineering, Physics, Math, or related STEM field3+ years (BS) or 1+ year (MS) in GNC, aerospace, or control systems engineeringExperience with MATLAB / Simulink (strong preference)Working knowledge of spacecraft dynamics, control systems, or simulation environmentsProgramming experience in C/C++, Python, or similarExposure to verification, validation, or system-level testingPreferredExperience with STK (Systems Tool Kit) or similar toolsBackground in spacecraft or aerospace systems (vs. purely academic controls work)Familiarity with flight software or embedded systems integrationExperience supporting real hardware or mission programs (big differentiator)Other RequirementsU.S. Citizenship requiredAbility to obtain and maintain a DoD Security ClearanceActive clearance (Secret+) is a strong plusWillingness to travel up to ~20% (including occasional international collaboration)
