Threat Systems Engineer Jobs (NOW HIRING)

Title: SETA Systems Engineer (Mid) KBR is seeking a Systems Engineer (SETA) to support our customer in Chantilly, VA. The Technical Professional (SETA) provides systems engineering and analytical support to help inform national security space decisions. In this role, you will integrate all-source intelligence with engineering analysis, modeling, and simulation to evaluate foreign space and counterspace capabilities and assess their implications for U.S. and allied space and ground architectures. You will contribute to trade studies, mission thread analysis, and test and evaluation planning to reduce technical risk for government programs. The position requires close coordination with partners across the Intelligence Community (IC), DoD, and mission stakeholders to ensure analytic rigor, traceability, and alignment with threat-informed requirements and CONOPS. You will produce high-quality technical assessments and briefings that support strategy, resourcing, and operational readiness.

Innovative Projects: KBR’s work is at the forefront of engineering, logistics, operations, science, program management, mission IT and cybersecurity solutions.

Collaborative Environment: Join a dynamic team that thrives on collaboration and innovation, fostering a supportive and intellectually stimulating workplace.

Impactful Work: Your contributions will be pivotal in designing and optimizing defense systems that ensure national security and shape the future of space defense.

Support threat-informed mission engineering activities, including end-to-end mission thread analysis, resiliency assessments, and deployment analysis.

Develop and execute modeling and simulation (M&S) cases using tools such as STK, AFSIM, or custom Python/MATLAB models to characterize system performance, coverage, and timelines.

Translate intelligence on foreign space and counterspace systems into technical requirements, measures of performance/effectiveness (MOP/MOE), and risk considerations for architectures and programs.

Coordinate with stakeholders across customer mission centers, Service components, USSF/SSC, the IC, and Combatant Commands to ensure analytic consistency and support decision processes.

Contribute to test and evaluation planning (developmental and operational), including modeling for test design, data sufficiency, and evaluation criteria.

Produce clear, technically grounded assessments, reports, and briefings on space threat systems and their implications for mission assurance and resilience.

Provide SETA support across the acquisition lifecycle, including requirements analysis, architecture decomposition, integration, verification/validation, and configuration management.

Apply analytic standards, review methodologies, and quality assurance practices to engineering and all-source analytic products.

Location: Chantilly, Va and Reston, VA [On-site]

Travel Requirements: Minimal

Working Hours: Standard 40 hours per week

Experience: 5-10 years in space, defense, or IC analysis or systems engineering, including exposure to space threat analysis or mission/architecture assessments within the IC/DoD environment.

Modeling & Simulation: Demonstrated experience using space mission M&S tools (e.g., STK, AFSIM, or equivalent) to support analytic or engineering tasks.

Architecture Knowledge: Working understanding of space and ground architectures, including interactions among mission, ground, and user segments.

Education: Bachelor’s degree in Engineering, Physics, Mathematics, Computer Science, or a related technical field from an accredited institution.
