Lead System Architect

KBR • El Segundo, CA

27d • $125,700 - $157,100 • Onsite

About The Position

KBR is seeking a Lead System Architect to join its MILSATCOM Systems Engineering, Integration and Test (MSEIT) team in El Segundo, California. The role supports Space Systems Command (SSC) by providing Model-Based Systems Engineering (MBSE) leadership for the Military Satellite Communications (MILSATCOM) capability area, including its next-generation protected SATCOM needs. The MSEIT contract provides systems engineering and integration support for the U.S. Space Force’s acquisition of secure, survivable, protected MILSATCOM systems.

The Lead System Architect provides technical leadership, direction, and oversight for program-wide system modeling. The role develops the MBSE strategy and model architecture, leads integrated system-model development and maintenance, and establishes traceability among mission needs, capabilities, architecture, requirements, interfaces, verification, and related engineering artifacts. It also coordinates model integration and governance across government and industry stakeholders and works with requirements, interface, and verification teams to ensure the model consistently represents the technical baseline.

The position is on-site, requires an active Secret clearance with eligibility for TS/SCI, and involves minimal travel. Standard working hours are 40 hours per week. The California salary range is approximately $125,700–$157,100, with the offered rate based on the candidate’s qualifications and internal parity. KBR may also offer other compensation, such as bonuses or relocation benefits, in accordance with its policies or contractual designations.

Requirements

• Active Secret clearance with eligibility for TS/SCI.
• Bachelor’s degree in engineering, computer science, or a related technical field.
• At least 5 years of experience in satellite systems, spacecraft development, or aerospace engineering.
• Demonstrated experience leading MBSE efforts for complex systems.
• Strong working knowledge of systems engineering principles covering architecture, requirements, interfaces, verification, validation, and configuration management.
• Demonstrated experience developing and managing complex system models using SysML.
• At least 4 years of hands-on experience with Cameo Systems Modeler/MagicDraw or comparable enterprise MBSE environments.
• Experience developing model structures, modeling conventions, viewpoints, relationships, and reusable modeling patterns.
• Experience establishing traceability among system architecture, requirements, interfaces, behaviors, and verification information.
• Experience with model configuration management, baselining, version control, and model governance.
• Ability to assess complex system models for technical completeness, consistency, and quality.
• Ability to translate engineering concepts and system relationships into coherent model structures that support technical decision-making.
• Demonstrated ability to coordinate technical activities across multidisciplinary engineering teams and organizations.

Nice To Haves

• TS/SCI clearance.
• At least 8 years of systems engineering experience, preferably supporting space, ground, or integrated space/ground systems.
• At least 3 years serving as an MBSE Lead, Lead System Architect, Chief Modeler, or equivalent technical leadership role.
• Advanced experience with Cameo Systems Modeler/MagicDraw, SysML, model libraries, profiles, and model governance.
• Experience integrating MBSE environments with requirements management, configuration management, test/verification, or other engineering-data environments.
• Experience with system-of-systems modeling and integration of complex space and ground architectures.
• Familiarity with DoD architecture and Digital Engineering approaches.
• Experience facilitating model-based technical reviews with government and industry stakeholders.
• INCOSE CSEP or ESEP certification, or similar systems engineering certification.
• Object Management Group Certified Systems Modeler Professional (OCSMP) Level 1 or higher.

Responsibilities

• Serve as the Lead System Architect for MBSE, providing technical leadership, direction, and oversight for system modeling activities across the program.
• Develop and maintain the program’s MBSE strategy, modeling approach, architecture, governance, and roadmap in alignment with systems engineering objectives and Digital Engineering initiatives.
• Define and maintain model architecture, including organization, decomposition, viewpoints, relationships, naming conventions, standards, and patterns.
• Lead development and maintenance of integrated system models representing architecture, requirements, behaviors, functions, interfaces, verification relationships, and other technical-baseline elements.
• Establish and maintain traceability among mission needs, operational capabilities, system architecture, requirements, interfaces, verification activities, and supporting engineering artifacts.
• Define approaches for integrating and, where appropriate, federating models and engineering data from government organizations, contractors, and other stakeholders.
• Evaluate contractor-developed models and modeling approaches for consistency with program architecture, requirements, technical-baseline objectives, and modeling standards.
• Manage the configuration of a Teamwork Cloud database employing multiple Project Usages.
• Manage data connectivity between Cameo System Modeler and IBM Rational DOORS.
• Work with requirements engineers to establish and maintain relationships and traceability between modeled architecture and authoritative system requirements.
• Coordinate with interface engineering teams to ensure interfaces, logical and physical connections, exchanges, and dependencies are consistently represented in the model.
• Work with verification and test organizations to incorporate verification methods, relationships, evidence, and system behavior into the modeling environment as appropriate.

Benefits

• 401(k) plan with company match.
• Medical, dental, and vision benefits.
• Life insurance and AD&D.
• Flexible spending account.
• Disability benefits.
• Paid time off.
• Flexible work schedule.
• Professional training and development.
• Other compensation may include bonuses, commissions, sign-on bonus, relocation benefits, short-term incentives, long-term incentives, or discretionary payments for exceptional performance, depending on job title or level and internal policy or contractual designation.
