Job description

Standard Job Description

Space is a critical domain, connecting our technologies, our security and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can do more - we can innovate, invest, inspire and integrate our capabilities to transform the future.

At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation. And we’re reimagining how space can connect us, ensuring security and prosperity.

Join us in shaping a new era in space and find a career that's built for you.

Mass Properties Engineering is the art and science of predicting the mass properties of a satellite, missile, aircraft, land vehicle or marine system before it is built, assessing and supervising the mass properties all through development, and finally performing highly accurate measurements to prove to our customers it will perform as proposed. Our Mass Properties Engineers help ensure our spacecraft get payloads to the right orbit around our planet or around other objects in our solar system, help our missile systems intercept a threat and protect our troops, help deliver a payload with pinpoint accuracy, or help us develop smaller, lightweight directed energy weapons, so they can be deployed on a variety of platforms.

As a Mass Properties Engineer, You Will

• Provide Mass Properties Engineering support to multiple missile, reentry systems, or special programs
• Calculate mass properties and update and maintain mass properties database
• Perform basic trade studies and make presentations at program design reviews
• Lead mass properties audits, develop test procedures and perform mass properties measurements, then reduce and interpret measurement data into final user values
• Facilitate Mass Properties Control Boards and weight reduction teams
• Document and publish all types of analysis reports
• Lead the mass properties effort on small programs

To promote the sharing of ideas, we at Lockheed Martin champion at work environment that supports differences and big-picture thinking.

You have opportunities to play an active role in strengthening the quality of life where we live and work by volunteering more than 850,000 hours annually.

Researches, plans, designs and develops mechanical products and systems such as instruments, controls, robots, engines, machines and mechanical, thermal hydraulic or heat transfer systems for production, transmission, measurement, and use of energy. Applies research to the planning, design, development, and testing of mechanical and/or electromechanical systems, instruments, controls, engines, and/or machines.

Basic Qualifications

• Proficiency in calculating the mass properties (mass, 3 axis centers of gravity, moments and products of inertia) of components and performing summation calculations into assemblies; developing simple software tools to perform these calculations
• Performing mass properties analysis to resolve weight, center of gravity, mass moments of inertia, and products of inertia from assemblies down to the component level; tracking changes impacting mass properties; preparing mass properties reports and supporting design reviews
• Interpreting detailed mechanism designs taken from manufacturing drawings or standard modeling software tools
• Demonstrated experience in weight and center of gravity measurements by platform and multiple load cell methods, data reduction, and simple error analysis
• Ability to develop and maintain mass properties databases and configuration control.
• Knowledge and proficiency in applying industry standards (e.g., AIAAS 120 2015, TR-2018-01203, SAWE RP-9, SAWE RP-10).
• Proficient in CAD (preferably PTCCreo) to extract component and assembly mass properties, perform model interrogation, and support engineering analyses.
• US Citizenship with a Secret security clearance required prior to start

Desired Skills

• Bachelor's degree in Engineering (Mechanical, Aerospace), Physics, or Mathematics
• Demonstrated understanding of and interactions of other mechanical analysis groups including stress, structural loads and dynamics, thermodynamics, aerodynamics, propulsion and power systems, as well as subsystem designers to promote mass properties efficient design alternatives
• In depth hands on experience with mass properties testing specifically with spin balance (rotary type) mass properties machines for aerospace components and assemblies, including: planning and executing spin balance test campaigns, leading static and dynamic balancing procedures, interpreting imbalance results, and applying corrective balance mass to bring parts within tolerance, documenting test results in compliance with aerospace standards and integrating findings into system level mass properties models.
• Experience with applying manual and statistical tolerance analysis (Root Sum Square (RSS), Monte Carlo, worst case, etc..).
• Serve as the mass properties SME for proposals/RFPs, quickly producing preliminary weight, balance, and inertia models using parametric estimations and historical data, and delivering clear, data driven analyses that support cost, performance, and schedule assessments.
