Job description

KBR’s National Security Solutions team provides high-end engineering and advanced technology solutions to our customers in the intelligence and national security communities. In this position, your work will have a profound impact on the country’s most critical role – protecting our national security.

The MILSATCOM Systems Engineering, Integration and Test (MSEIT) team in support of Space Systems Command (SSC) in El Segundo is seeking an individual to provide requirements development and management support for the Military Satellite Communications (MILSATCOM) Capability area. The MILSATCOM portfolio of programs has an ongoing need for IA/Cybersecurity support, to meet the needs of our emerging next-generation protected SATCOM.

The MSEIT contract provides leading-edge Systems Engineering & Integration (SE&I) support for the U.S. Space Force’s SSC. We support the Space Force’s acquisition of state-of-the-art MILSATCOM systems, providing global secure, survivable, and protected communications for our nation’s warfighters. We seek technical individuals who will thrive in a highly collaborative work environment of small teams, using the most modern tools and methodologies to tackle the challenges of integrating complex space and ground communications systems.

Why Join Us?

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

Collaborative Environment: Be part of 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.

Key Responsibilities:

Develop, refine, and maintain system requirements using DOORS to ensure alignment with mission objectives, operational needs, acquisition strategy, and technical baseline priorities.

Evaluate requirements for quality, completeness, consistency, feasibility, testability, and compliance with program standards, regulatory requirements, and systems engineering best practices.

Coordinate and collaborate with government stakeholders, prime contractors, support contractors, and subject matter experts to resolve requirement gaps, conflicts, ambiguities, and implementation concerns.

Work closely with the Configuration Management team in preparing for Engineering Review Boards (ERBs) and Configuration Control Boards (CCBs)

Identify requirements related risks and drive technical issue resolution across engineering teams.

Support system integration and test activities by providing authoritative requirement documentation and clarification.

Analyze contractor deliverables, technical proposals, and change packages to determine impacts to requirements, verification scope, interfaces, cost, schedule, and technical risk.

Facilitate requirements reviews, working groups, and technical interchange meetings to drive stakeholder alignment and timely disposition of comments, issues, and action items.

Ensure requirements products remain synchronized with architecture models, interface documentation, CONOPS, test planning products, and acquisition documentation.

Develop acquisition and technical requirements-related briefings, plans, papers, and other documentation in support of government decision making.

Develop and maintain verification planning products, including verification cross-reference matrices, verification approaches, success criteria, responsible organizations, and evidence expectations for assigned requirements.

Coordinate with integration, test, cybersecurity, modeling, and subject matter expert teams to align verification activities with program schedules, test resources, operational scenarios, and technical baseline constraints.

Review verification artifacts, test plans, procedures, analysis reports, and contractor-provided evidence to determine whether requirement verification intent and acceptance criteria are adequately addressed
