This position will provide systems engineering and mass properties integration support to the MSFC Systems Analysis Branch (EV74) for the Space Launch System (SLS) vehicle and its configurations.


The successful candidate will coordinate and interface with the mass properties & integrated analysis personnel in EV74, the SLS Program team and personnel, the SLS Element teams and personnel, and the stakeholders in the guidance, navigation, and control disciplines as well as participate in reviews, meetings, working groups, and trade studies.


The systems engineering and mass properties analysis support to be provided and performed includes:


  • Perform conceptual mass properties parametric estimations, bottoms-up calculations, mass distributions, moment and product of inertia calculations, and weight control planning.
  • Coordinate with customers and stakeholders in the GN&C, operations, and performance disciplines/areas.
  • Collect, integrate, and record data from drawings and populate and maintain mass properties databases.
  • Coordinate with designers and stress analysts for improved mass savings in design and manufacturing.
  • Evaluate SLS Prime Contractor mass properties reports and their associated mass properties data.
  • Coordinate mass estimations and provide technical insight, uncertainty analysis, and appraisal of the conservatism used in their estimating process.
  • Generate Technical Performance Metric (TPM) charts for the SLS vehicle configurations.
  • Create Mass Properties Reports which will include full dry mass properties (mass, center of gravity, moments of inertia, and products of inertia) as well as other reports suitable for input into trajectory and guidance navigation and control (GN&C) design and analysis assessments.
  • Participate in reviews, meetings (i.e. team/discipline, TIMs, teleconferences, etc.), working groups and trade studies to complete assigned tasks.
  • Participate in the planning and execution of the verification and validation of SLS vehicle and Element mass properties requirements.
  • Participate in post-flight analysis and assist with post-flight mass properties reconstruction for the SLS vehicle configurations.
  • Create and implement new processes and tools to facilitate improved design and analysis capabilities to verify and validate mass properties data.






A Bachelor’s degree or higher in mechanical, aerospace, or civil engineering or a degree in a related technical discipline such as physics or mathematics from an ABET accredited institution is required.  Typical educational requirements are the equivalent of a Masters or a BS with at least 4 years of experience in systems engineering, guidance navigation and control, and/or mass properties/weight management is required.


  • Excellent mathematical skills and the ability to perform analytical assessments of vehicle systems, subsystems, and components is required.
  • Must have experience working with design teams, with system configuration and analysis disciplines, and with guidance and navigation stakeholders.
  • An understanding of mass properties uncertainties as well as sequenced and non-sequenced mass properties is required.
  • Must be able to breakdown complex problems or issues into manageable pieces to facilitate resolution of technical concerns.
  • Experience reading and working with engineering drawings, interface control documents, configuration documents, or other technical documentation is required.
  • Experience using MATLAB and some proficiency creating tools or modifying software applications for a specific use is required.
  • Critical thinking, effective communications, and problem solving skills are required.
  • Experience coordinating the planning and execution of the verification and validation of mass properties requirements is highly desired.
  • Knowledge of trajectory software programs (i.e. POST, MAVERIC, 3DOF trajectories, and 6DOF simulations) and how the mass property data feeds into them is highly desired.
  • Experience using computer aided design tools (i.e. Pro-E/CREO) and database applications is desired.
  • Experience with launch vehicles and spacecraft post-flight mass properties reconstruction is desired.
  • Excellent oral, written, interpersonal, customer relation skills, and presentation skills are required.
  • Intermediate skills using Microsoft Office Suite (Word, Office, Excel, PowerPoint, and Outlook) are required.
  • An understanding of the NASA/contractor environment, NASA systems engineering processes, and familiarity with the SLS Program is desired.


Prior experience working in a dynamic work environment will serve to prepare a self-directed and effective team player to assume the role of a Systems Engineer and Analyst for the SLS mass properties integration effort.
