Orbital Analyst Senior

York Space Systems is seeking a Senior Orbital Analyst Senior/ Flight Dynamics Engineer to lead the design, analysis, and on-orbit support of spacecraft flight dynamics and mission analysis across a range of commercial and national security missions. This individual will serve as a technical leader within the Flight Dynamics team, working across multiple programs to define subsystem architecture, develop algorithms and models, support verification and flight operations, and mentor junior engineers.     Responsibilities Include: Own mission and system level analysis ensuring space vehicle designs meet or exceed requirements across subsystems. Define and maintain high-fidelity simulation environments to support development of mission architecture and day in the life analysis for a variety of different missions. Lead development of mission concept of operations. Identify, create, and use available tools to model and analyze a given system’s performance and capability in relation to mission objectives. Design and analyze constellation architectures, including orbital regimes, plane spacing, phasing strategies, and deployment concepts. Perform trade studies for various mission designs to meet contact coverage, lifetime, regulatory requirements, and validate mission feasibility. Serve as the flight dynamics/mission analysis 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 a flight dynamics subject matter expert.  Support spacecraft mission operations, and anomaly investigation using telemetry and flight data during planning and execution phases. Provide technical direction and mentorship to junior engineers and contribute to the development of team processes, standards, and best practices.   Develop and validate flight dynamics software partnering with mission operations, spacecraft subsystems, and software engineering teams to support mission design, on orbit operations, and contract phases      Qualifications   A bachelor’s degree in aerospace engineering, computer science, or related technical field from accredited university; Advanced degree preferred. 4+ years of experience in spacecraft GNC, mission analysis, orbit analysis, flight dynamics systems or similar. Strong background in orbital dynamics and spacecraft subsystems. Proficiency with industry-standard tools such as STK, GMAT, or equivalent.  Demonstrated experience analyzing spacecraft dynamics, control theory, and propulsion performance as they relate to trajectory design and constellation geometry. Experience with NASA ORDEM, NASA BUMPER, NASA DAS, NASA MEM3 desired Familiarity with conjunction assessment approaches and collision avoidance workflows. Proficiency with Python software development. Proficiency with Git version control, or an equivalent version control system.  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. Must be able to obtain and maintain a U.S. security clearance; U.S. citizenship required. Active security clearance preferred.
