How you’ll make a difference 

• Lead the establishment and governance of a requirements management framework across projects by administering and optimizing the requirements database (e.g., DOORS), including its structure, controls, versioning, and integration, while ensuring end-to-end traceability, enforcing quality standards and review processes, and supporting stakeholders through training, coaching, and troubleshooting.
• Coordinate systems engineering and integration across multiple venues and domains by defining and managing interfaces between systems and delivery partners, addressing cross-venue dependencies and risks, and supporting integration planning, staging, readiness, and operational transition.

• Engage and collaborate with a wide range of stakeholders—including venue delivery teams, technology providers, and government agencies—by facilitating requirements workshops and integration forums, providing clear, evidence-based advice on status and risks, and acting as a key interface between engineering, operations, and program management teams.
