KBR is proud to work with its customers across the globe to provide technology, value-added services, and long-term operations and maintenance services to ensure consistent delivery with predictable results.

Trinzic is the future independent company to be created through the planned spin-off of KBR's Mission Technology Solutions business, expected in January 2027. Our people work at the frontier of what is possible, delivering solutions in challenging environments and advancing some of the world's highest-priority national security and space missions.

Backed by decades of mission success, deep expertise, and trusted partnerships, Trinzic will launch as a global organization with more than 18,000 employees supporting customers around the world. Join us at a defining moment and help shape the future of a company built to tackle complex challenges and make a meaningful impact.

Candidates who join KBR's Mission Technology Solutions business before the spin-off will transition to Trinzic when the separation is complete and will not need to reapply for employment.

Position SummaryKBR is seeking a Senior/Principal Systems Modeling & Simulation/Systems Engineer to join the Structural Engineering and Analysis team supporting NASA Goddard Space Flight Center Programs. This position would provide structural engineering, analysis, and test support for a wide range of cutting edge and exciting aerospace projects including space telescopes, earth science satellites, Mars, Moon and asteroid science missions, robotic servicing missions, and associated mechanical ground support equipment.ResponsibilitiesIM Modeling & Systems AnalysisDutiesImplement necessary changes to convert the standard STOP structural model to support composite moisture desorption analysis for both steady state and transient cases; the latter includes coordination with thermal modelers/analysts to enable temperature mapping onto the structural model and implementation of temperature variability for key variables

Perform steady state and transient moisture desorption analysis for flight and TVAC test cases with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model propertiesInvar Growth AnalysisImplement necessary changes to convert the standard STOP structural model to support Invar growth analysis

Perform steady state Invar growth analysis for flight cases with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model propertiesGravity Release AnalysisImplement necessary changes to convert the standard STOP structural model to support gravity release analysis

Perform gravity release analysis with primary responsibility for recovering distortions and coordinating with opto-mechanical and optical analysts to recover optical performance metrics

Perform Monte Carlo analysis as necessary to validate Model Uncertainty Factors (MUF) based on variability of key model propertiesSTOP Pipeline Tool DevelopmentDutiesMaintain and improve on an existing script database which includes tens of thousands of lines of custom code tailored to Roman and Habitable Worlds Observatory analysis workflows for Structural-Thermal-Optical Performance (STOP) analysis

Work with performance stakeholders (science, systems, optical, etc.) to define performance metrics that support understanding of overall observatory, telescope, and instrument optical performance; develop corresponding analysis scripts

Implement new analysis capabilities into the STOP pipeline tool to support analysis cycle objectives; this includes, but is not limited to adding functionality for composite moisture desorption and Invar growth analyses, and others as necessary

Identify and implement analysis process automation features as well as integrate the STOP Pipeline tool with separate industry toolsets that facilitate iterative systems analysis methods
