Mass Properties and Integration Systems Engineer - Lunar Permanence Blue Origin $110,938.00-$169,432.20 life insurance, parental leave, paid time off, paid holidays, 401(k), stock options United States, Florida, Merritt Island 8082 Space Commerce Way (Show on map) Sep 04, 2026 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 the Lunar Permanence business unit, which develops Blue Origin's Blue Moon landers and related products. To further Blue Origin's mission of millions of people living and working in space for the benefit of Earth, we are building sustainable infrastructure for our transport of crew and cargo from Earth to the lunar surface. We are looking for a Systems Engineer III to support mass properties engineering for the Mk1 Transfer Stage. This role owns the day-to-day maintenance and analysis of the mass-properties Bill of Materials (BOM), supports 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. As a Systems Engineer II on this team, you won't just track mass - you'll actively work with Fluids, Avionics, Thermal, GN&C, and Structures to find where mass can come out of the vehicle, and partner with manufacturing on trades that balance metrics for the best cost to performance ratio for our customers. Your work directly supports program-level decisions and keeps the vehicle within its mass and CG requirements throughout design, build, and test. Beyond tracking and reporting, 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 partnering with manufacturing teams on trade studies that balance mass, cost, and producibility. This is a strong fit for an engineer who wants hands-on ownership of a critical vehicle integration discipline, is comfortable getting into the design weeds with other subsystems, and enjoys cross-functional collaboration, hardware exposure, and design reviews. 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 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 mas margin management

Proficiency with Python and/or MATLAB for data tracking, reduction, and reporting

Ability to earn trust, maintain positive and professional relationships, and give to a culture of inclusion.

Excellent written and oral communication skills.

Minimum of a 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

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

Clear written and verbal communication, with ability to present technical findings to a multi-disciplinary audience Base Pay Range for: CO applicants is $110,938.00 - $155,312.85 WA applicants is $121,023.00 - $169,432.20 Other site ranges may differ Culture Statement Don't meet all desired requirements?
