Mass Properties and Integration Systems Engineer - Lunar Permanence Verified today

About the Role

This role is part of the Lunar Permanence business unit, which develops Blue Origin's Blue Moon landers. You will support mass properties engineering for the Mk1 Transfer Stage, owning the day-to-day maintenance and analysis of the mass-properties Bill of Materials (BOM), mass property predictions, and tracking across the vehicle lifecycle.

You'll work closely with design, manufacturing, integration, and test teams to ensure the vehicle's mass, center of gravity, and moments of inertia are understood, tracked, and reported accurately at every program milestone. Mass properties data underpins nearly every other engineering discipline on the vehicle, from structural margins to guidance and control to propellant budgeting.

This role is expected to dig into subsystem designs to find and drive mass reduction opportunities. You'll build close working partnerships with system leads championing minimum-mass solutions and partner with manufacturing teams on trade studies that balance mass, cost, and producibility.

What You'll Do

• Maintain the Mk1 Transfer Stage mass-properties model keeping component mass, CG, and inertia data accurate and traceable as the design matures
• Support mass roll-ups and margin tracking against stage allocations, flagging growth trends to responsible subsystem leads and program leadership
• Reconcile predicted against measured mass properties and support root-cause investigations when discrepancies appear
• Assist planning and execution of stage and vehicle-level CG and weighing operations, including test setup coordination and data analysis
• Identify downstream consumers of mass properties data and best methods of delivering that data to the teams
• Track propellant loading and burn-state mass properties across mission phases, from launch through docked configuration
• Generate routine status reports and present findings at design reviews, program milestones, and regular status meetings
• Maintain configuration control of mass properties documentation per program process
• Document assumptions, threats, methods, and uncertainty in all mass estimates
• Own the Transfer Stage mass budget and allocation flow-down to subsystems, negotiating reallocations as the design matures
• Champion minimum-mass solutions across Fluids, Avionics, Thermal, GN&C, and Structures, and drive reduction opportunities to closure
• Lead mass trade studies with manufacturing, balancing mass against cost, schedule, and producibility
• Serve as the responsible engineer for mass properties at program gated reviews
• Define the uncertainty and margin methodology, and set MGA policy by design maturity

Required Qualifications

• 5+ years of demonstrated ownership of mass budget
• Working proficiency with CAD tools (CATIA, NX, SolidWorks, or Creo), able to navigate and interpret subsystem detailed assemblies
• Demonstrated understanding of center of gravity, moments and products of inertia, and mass margin management
• Proficiency with Python and/or MATLAB for data tracking, reduction, and reporting
• Excellent written and oral communication skills
• Minimum B.S. degree in Aerospace Engineering, Mechanical Engineering, or related engineering discipline
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum

Preferred Qualifications

• Experience with BOM-based mass properties tracking on a flight vehicle or spacecraft
• Familiarity with rendezvous, proximity operations, or docking dynamics and how mass properties drive them
• Exposure to propulsive-stage mass accounting, including propellant loading and burn-state mass properties
• Experience supporting physical weighing or CG measurement operations, or critical lift planning
• Strong attention to detail when working with large, evolving datasets and changing configurations
