This role is tailored for deep-space mission design primarily supporting civil missions in Mars and cislunar space, but candidates with clearance may have opportunities to contribute across the full range of ATX mission work long-term. ## Description You'll join the Astrodynamics and Trajectory Execution (ATX) team, which is responsible for end-to-end trajectory design and ground navigation within In-Space Systems. We are growing ATX to fly missions to the Moon and Mars using high-thrust and low-thrust propulsion, and to build an operational deep-space mission design capability from the ground up. In this hands-on role, you will independently own significant portions of the mission design process for an entire mission, spanning analysis, software development, and live flight operations, helping shape how our team designs trajectories for years to come. Your Impact: * Own Lifecycle Mission Design: Drive mission design through mission-level requirements, gated reviews, mission rehearsals, and flight operations. Author trajectory design reports, maneuver plans, and operations procedures. * Design and Optimize Trajectories: Design and optimize high-thrust and low-thrust trajectories, including lunar transfers, libration point and multi-body orbits, lunar frozen and low lunar orbits, interplanetary cruise, planetary capture, interplanetary low-thrust transfers, and many-revolution spirals, accounting for tracking geometry and navigation performance. * Fly Deep Space Missions: Design deterministic, trajectory correction, statistical, orbit insertion, and station-keeping maneuvers from launch through end of mission. Perform live maneuver operations, making maneuver-readiness recommendations under real-time constraints, and partner with navigators to incorporate orbit determination solutions into targeting and assess burn performance. * Define Launch Periods and Mission Timelines: Determine launch periods and deliver daily launch targets through the launch vehicle interface control document. Own the trajectory-driven timelines that anchor mission CONOPS. * Own Delta-V Budgets and Mission Performance: Maintain deterministic, statistical, and margin delta-v allocations across high-thrust and low-thrust phases that result in feasible mission architectures. Lead trajectory contributions to performance analysis cycles that verify and validate mission requirements, using ATX's AWS-powered Monte Carlo capability. * Develop Maneuver Algorithms and Tools: Develop and test trajectory and maneuver algorithms in Python, Julia, and Monte. Partner with the flight dynamics software architect to infuse them into ATX's Monte-based flight dynamics system. * Drive Automation: Automate trajectory design, maneuver planning, and analysis workflows as ATX scales toward fleet-level operations, including through generative AI. * Collaborate and Grow the Team: Work with ATX, propulsion, systems engineering, flight operations, and launch provider teams. Represent mission design in reviews, and mentor junior mission designers., Applicants for employment at Blue Origin must be a U.S. citizen or national, U.S. permanent resident (i.e. current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Background Check * Required for all positions: Blue's Standard Background Check * Required for Certain Job Profiles: Defense Biometric Identification System (DBIDS) background check if at any time the role requires one to be on a military installation * Required for Certain Job Profiles: Drivers who operate Commercial Motor Vehicles with a Gross Vehicle Weight (GVW), Gross Vehicle Weight Rating (GVWR) or combination of power unit and trailer that meets or exceeds 10,001 lbs. and/or transports placardable amounts of hazardous materials by ground in any vehicle on a public road while in commerce, may be subject to additional Federal Motor Carrier Safety Regulations including: Driver Qualification Files, Medical Certification (obtained before onboarding), Road Test, Hours of Service, Drug and Alcohol Testing, vehicle inspection requirements, CDL requirements (if applicable) and hazardous materials transportation/shipping training. * Required for certain Job Profiles: Ability to obtain and maintain Merchant Mariner Credential, which includes pre-employment and random drug testing as well as DOT physical
