Deep Space Mission Design Engineer III

Application close date:
Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role is part of Blue National Security (BNS), where our focus is the design, development, and delivery of launch and spacecraft systems for national security missions. Through Blue Ring, our all-in-one, high-powered hybrid solar-electric and chemical-propelled spacecraft, we provide unmatched mission maneuverability, versatility, and capacity at dramatically lower-profile costs. Blue Origin's In-Space Systems business unit operates spacecraft across some of the most demanding regimes in spaceflight, from geostationary orbit to cislunar space and interplanetary destinations.

Blue Ring, our multi-mission space vehicle, is expanding where we fly and what our mission design capabilities must do.

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.

• 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:
