GS2 Engine integration lead

Application close date:

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! 

As part of a hardworking team of engineers, you will be responsible for integrating the Liquid rocket engine with the GS2 vehicle, with a focus on fluid systems, structural interfaces, and interface control documentation (ICD) and specifications.

• Own the technical integration of the engine to the GS2 stage, including all fluid and structural interfaces.
• Define, develop, and maintain engine–vehicle Interface Control Documents (ICDs), ensuring alignment across BE‑3U and GS2 stakeholders.
• Develop and manage system- and subsystem-level specifications for BE‑3U/GS2 interfaces (fluid, structural, electrical, and avionics as needed).
• Lead the design and integration of fluid interfaces (propellant, pressurization, purge, vent, and drain) between engine and stage, including line routing, manifolds, and valves.
• Coordinate loads, environments, and interface requirements with analysis teams (structures, dynamics, thermal, and fluids) and incorporate results into ICDs and specs
• Support test planning and test execution for BE‑3U/GS2 integrated testing (component, subsystem, and system-level), including test configurations and data review.
• Drive resolution of interface and design changes via structured change control, including updates to ICDs, specs, and configuration baselines.
• Provide clear technical communication (presentations, review packages, and trade studies) to leadership and cross‑functional teams.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 3+ years of relevant experience in propulsion, launch vehicle, or complex aerospace system integration.
• Experience with fluid systems (cryogenic propellants, pressurization, or pneumatic systems) and structural interfaces in propulsion or vehicle applications.
• Demonstrated experience creating and managing ICDs, requirements, or specifications for complex hardware.
• Proficiency with engineering tools for CAD, drawings, and requirements management (e.g., Creo/Windchill, DOORS/Jama, or equivalent).
• Experience working in multi‑disciplinary teams and driving closure on interface issues across organizations.

• Master’s degree in Mechanical or Aerospace Engineering, or related discipline.
• 5+ years of experience integrating rocket engines with launch vehicle stages or similar propulsion–structure systems.
• Hands‑on experience with cryogenic oxygen and hydrogen systems, including ground test or flight hardware.
• Experience with structural loads, dynamic environments, and test‑correlation for engine or stage attachments.
• Experience in configuration management and formal change processes for ICDs and specifications.
