Systems Engineer II - Mass Properties & Bill of Materials

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 II to support mass properties engineering for the Mk1 Lunar Cargo Lander. 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, and assists with physical center of gravity (CG) measurements and verification activities. 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 and update the mass-properties Bill of Materials (BOM), ensuring component-level mass, CG, and moment of inertia data is accurate, traceable, and current as the design matures
• Support mass property roll-ups and margin tracking against allocations, flagging discrepancies or growth trends to the responsible engineering leads
• Assist in planning and executing vehicle-level CG measurements, including coordination of test setup, data collection, and reduction of results
• Reconcile predicted vs. measured mass properties and help drive root-cause investigations when discrepancies arise
• Generate routine mass properties status reports and present findings at design reviews and program milestones
• Coordinate with subsystem leads and component owners to collect updated weight and CG data, including CAD-derived and as-built/as-weighed values
• Partner with Fluids, Avionics, Thermal, GN&C, and Structures teams to identify, evaluate, and drive mass reduction opportunities across the vehicle
• Act as a champion for minimum-mass design solutions, bringing a mass-conscious perspective into cross-functional design discussions and trade studies
• Deep-dive into subsystem and component designs (CAD, drawings, analyses) to identify mass growth risks, over-design margins, and reduction opportunities
• Support mass trade studies with manufacturing teams, weighing options for material substitution, process changes, and design simplification against cost, schedule, and producibility
• Support development and upkeep of mass properties tools, templates, and databases used for tracking and reporting
• Participate in vehicle weighing operations and other physical measurement activities, including instrumentation setup and basic data analysis
• Help maintain configuration control of mass properties documentation in accordance with program processes
• Document assumptions, methods, and uncertainty/margin in mass property estimates

What We're Looking For

Required:

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or related engineering discipline
• 1–3 years of relevant experience working in aerospace.
• Strong working proficiency with CAD tools (e.g., CATIA, NX, SolidWorks, Creo), with the ability to navigate and interpret subsystem designs and assemblies, not just extract summary data
• Solid understanding of mass properties concepts: center of gravity, moments/products of inertia, mass margin/contingency management
• Comfort engaging directly with design and analysis details to identify mass reduction opportunities, including reading drawings, models, and structural/thermal/fluids analyses well enough to ask informed questions
• Strong attention to detail and comfort working with large, evolving datasets, changing configurations, and rapid customer responses.
• Proficiency with Excel, Matlab, or Python or similar tools for data tracking and reporting
• Clear written and verbal communication skills, with the ability to work cross-functionally and present technical findings, including mass trade recommendations, to a multi-disciplinary audience

Preferred:

• Exposure to BOM-based mass properties tracking on a flight vehicle, spacecraft, or similar complex system
• Experience supporting or observing physical weighing/CG test operations or rigging and other high criticality vehicle movements. Bonus for experience with critical lift plans
• Experience supporting design or mass trade studies in partnership with manufacturing or production engineering teams
• Understanding of how mass properties data flows into and interacts with Space Vehicle design along with Fluids, Avionics, Thermal, GN&C, and Structures analyses
• Basic scripting/automation skills (Python, MATLAB, or VBA) for data processing
