Job description

Senior Modeling & Simulation Engineer

At KBR, we deliver science, technology and engineering solutions to governments and companies around the world. KBR employs approximately 37,000 people worldwide with customers in more than 85 countries and operations in over 28 countries. 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.

Key Responsibilities

KBR is seeking a Senior Modeling & Simulation Engineer to join a dynamic, high-performing, multi-disciplinary team consisting of operational military and intelligence subject matter experts (SMEs), operations research analysts, modelers, and software engineers who conduct modeling, simulation, and analysis (MS&A) of emerging concepts using advanced MS&A techniques and tools. This team employs mission engineering, Joint operational planning, and emerging operational concepts to conduct kill chain and kill web analyses in support of combatant commands and Echelon 1 Department of War stakeholders. The selected candidate will:

• Independently execute modeling, simulation, and analysis tasks in support of mission engineering studies and operational analyses. Provide technical recommendations and contribute to the planning and execution of study activities.
• Be able to think creatively and offer grounded, out-of-the-box solutions when appropriate.
• Be comfortable working in a dynamic environment and with making or supporting decisions under uncertainty.
• Support modeling, simulation, and software development efforts across the full analytic and software development lifecycles.
• Support study execution through development of models, experiment designs, data collection, and analytic products.
• Collaborate with military subject matter experts and other stakeholders to characterize architectures and concepts under study in the simulation environment.
• Apply established modeling approaches, experiment designs, and analytic methods while contributing recommendations for improvement.
• Instantiate combat system, platform, and behavior models in the simulation environment.
• Instantiate kill chains, battle management command and control relationships, and other scenario-specific mission and operational factors in the simulation environment.
• Support the development and instantiation of an experiment design in the simulation environment.
• Collaborate effectively with multidisciplinary teams and share technical expertise with peers when appropriate. Lead focused modeling, simulation, or analysis tasks and coordinate activities across multidisciplinary team members as required.
• Contribute to the creation of quality deliverables and reports and quality control thereof.
