This engineer will support and enhance Space Domain Awareness (SDA) operations by performing advanced orbital analysis, improving analytical methods and tools, and integrating data from space object tracking sensors and networks. The role bridges operational SDA needs with engineering rigor to improve the accuracy, responsiveness, and effectiveness of national security space operations. While most work is performed Monday through Friday during normal duty hours, occasional work outside these hours may be required in support of non-routine operations or mission events.\nResponsibilities include, but are not limited to:\nPerform advanced orbital analysis in support of SDA missions, including orbit determination, orbit prediction, conjunction assessment, orbit decay modeling, and maneuver evaluation for station-keeping and changes of station.\nSupport the development, refinement, and optimization of analytical methods, processes, and workflows used for spaceflight safety, mission protection, and space defense operations.\nIntegrate and assess data from space object tracking sensors and networks, evaluate data quality and sensor performance, and recommend improvements to data usage and processing.\nConfigure and employ tools such as the Astrodynamics Support Workstation (ASW), Atlas, or similar astrodynamics/orbital analysis software, and support their integration into operational SDA environments.\nContribute to the development and maintenance of technical documentation, including concepts of operations (CONOPS), standard operating procedures (SOPs), and engineering reports that support SDA and space defense missions.\nCollaborate with operators, analysts, and other engineers across space operations centers, intelligence organizations, and space acquisition offices to ensure that engineering solutions address operational needs.\nProvide technical guidance and subject matter expertise in orbital mechanics and astrodynamics to support troubleshooting, anomaly resolution, and enhancements to SDA capabilities.\n Bachelor’s degree in Aerospace Engineering, Astronautical Engineering, Physics, Mathematics, or a closely related STEM field and 3-9 years of relevant space systems engineering or orbital analysis experience.\nDemonstrated expertise in orbital mechanics and astrodynamics, including:\nOrbit determination and estimation methods.\nOrbit prediction and propagation.\nGeneral and special perturbation techniques.\nOrbit decay and reentry considerations.\nOrbital maneuvers for station keeping and changes of station.\nExperience performing orbital analysis or astrodynamics engineering in support of operational space missions (Department of Defense, Intelligence Community, civil, or commercial).\nExperience working with space object tracking sensors, networks, and associated data, and understanding their capabilities and limitations.\nFamiliarity with Linux-based operating systems, particularly Red Hat Linux, and experience using astrodynamics and/or analysis tools in that environment.\nProficiency with Microsoft Office (Word, Excel, PowerPoint) and strong written and verbal communication skills, including the ability to document and present technical analysis to both technical and non-technical audiences.\nClearance Requirements:\nActive TS/SCI with a current Polygraph\nPreferred Qualifications:\nExperience supporting the 18th Space Defense Squadron, other Space Force SDA units, or similar operational space organizations.\nHands-on experience with Astrodynamics Support Workstation (ASW), Atlas, or similar astrodynamics/orbital analysis tools beyond basic user-level operation (e.g., configuration, advanced analysis, or workflow optimization).\nExperience improving analytical processes or tools supporting spaceflight safety, conjunction assessment, or space defense operations.\nExperience in an operations center or mission environment where engineering support is provided to real-time or near-real-time decision-making.\nExperience interpreting, drafting, or implementing technical portions of space-related policies, plans, and procedures.\nPhysical Requirements:\nWork is primarily performed in an office and/or operations center environment at Vandenberg Space Force Base.\nMust be able to sit or stand for extended periods while using a computer and standard office equipment.\nMay be required to work outside normal duty hours on occasion to support non-routine operations or mission events.\n2026.10.1","description_format":"text","description_chars":4660,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
