Job summary

Blue Origin in Merritt Island, FL is seeking a Systems Engineer III to own mass properties for the Mk1 Transfer Stage and to maintain mass, CG, and inertia data as the design evolves. You will work with design, manufacturing, integration, and test teams to balance mass with performance.

The role focuses on reducing mass while ensuring safe, producible designs, performing trades with manufacturing, and presenting findings at design reviews and program milestones.

Qualifications

• 5+ years of demonstrated ownership of mass budget.
• Proficiency with CAD tools (CATIA, NX, SolidWorks, or Creo).
• 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.
• Must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S.

Responsibilities

• 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.
