Impactful Work: Your contributions will help transform the existing weapon architecture into a practical Government-owned framework that expands the industrial base increases competition accelerates technology innovation lowers integration and weapon-system costs and enables production to scale more rapidly.

KBR is seeking a highly experienced Principal Systems Engineer and Modular Systems Architect to support a U.S. Government organization responsible for advancing the Weapons Government Reference Architecture (GRA) and Weapons Open Systems Architecture (WOSA) for conventional weapon systems. The purpose of this effort is not simply to produce a more complete architecture model. It is to extend the current architecture into an actionable Government-owned framework that enables a broader and more competitive industrial base creates viable entry points for nontraditional and component-level suppliers accelerates insertion of new technologies reduces dependence on closed or vertically integrated solutions lowers redesign and integration costs and supports scalable production across a family of weapon systems.

Key Responsibilities

• Serve as the principal systems engineer and architect for evolving the Weapons GRA and WOSA into an implementable framework that supports industrial-base expansion supplier competition technology insertion affordability production scalability and Government control of critical technical interfaces and data.
• Communicate detailed architecture interface SysML and MBSE concepts with Government and industry engineers while translating the technical approach tradeoffs risks and value into clear decision-relevant terms for senior leaders and non-specialist stakeholders.
• Architect and lead the Model-Based Systems Engineering (MBSE) effort needed to define the physical parameters interfaces constraints attributes and model-based severable data packages that make those outcomes possible.
• Lead the effort to augment and refine the existing Weapons GRA framework so it can be applied across current and future Air Force conventional weapon programs to reduce unnecessary program-unique design increase reuse and create repeatable pathways for integrating qualified subsystem solutions.
• Extend established WOSA domains to include parameters constraints interface characteristics form-factor considerations environmental conditions and other attributes necessary to govern physical modularity.
• Define the structure content technical requirements configuration controls intellectual-property boundaries and acceptance criteria for model-based severable data packages that allow subsystem solutions to be competed developed evaluated integrated and replaced with less dependence on a single weapon integrator.
• Develop architecture viewpoints system models interface definitions requirements relationships reusable model libraries and reference patterns that provide suppliers with clear technical entry points while protecting system-level integration integrity.
• Apply SysML and MBSE methods to maintain traceability among mission needs requirements logical architecture physical architecture interfaces verification methods and production considerations.
• Evaluate how modular physical interfaces and severable data packages can support rapid insertion and competition of seekers propulsion systems payloads mission electronics guidance components datalinks power systems and other domain solutions from traditional and nontraditional suppliers.
• Identify architecture decisions and interface standards that reduce redesign non-recurring engineering integration time qualification burden supplier lock-in production disruption and total weapon-system cost.
• Define architecture and data-package approaches that allow the Government to compete domain solutions independently where appropriate without compromising weapon-level safety performance cybersecurity airworthiness or integration responsibility.
• Identify where common interfaces and reusable architecture products can create sufficient demand across programs to attract new suppliers justify private investment and improve the business case for innovative technologies and expanded manufacturing capacity.
• Evaluate the tradeoffs between standardization and mission-specific optimization to ensure modularity improves competition affordability and production flexibility without imposing unnecessary performance penalties or constraining future design innovation.
• Define proof-of-concept efforts that demonstrate whether model-based severable data packages and physically modular domain solutions can reduce integration time and cost enable supplier substitution and support production scaling without unacceptable performance or qualification risk.
• Assess architectures and models for completeness consistency interoperability configuration integrity usability extensibility affordability implications supplier accessibility and alignment with Government open-systems and industrial-base objectives.
• Coordinate with Government program offices technical authorities digital engineering teams test organizations acquisition stakeholders and industry partners.
• Lead or support architecture reviews model reviews interface working groups design reviews and technical interchange meetings.
• Deliver incremental architecture releases and demonstrate how each release improves technical clarity supplier accessibility modularity competition integration speed affordability or production scalability.
• Deliver a final release package at the conclusion of the period of performance including documentation examples and a reference implementation to support future Government modeling efforts applying the delivered architecture.
