  • Collaborate with Product Managers, Release Train Engineers (RTEs), and cross-functional scrum teams to translate business needs into technical solutions that meet performance, scalability, security, and compliance requirements.
  • Guide technical decision-making across geographically dispersed teams to ensure consistent design patterns, coding standards, and DevSecOps practices.
  • Conduct architecture reviews and provide governance to ensure solutions are compliant with federal enterprise architecture frameworks, cybersecurity mandates (e.g., NIST), and cloud adoption strategies.
  • Define, update, and validate architectural patterns and interface specifications for enterprise-level systems.
  • Drive cloud-native solution strategies including containerization, and continuous integration/continuous delivery/deployment (CI/CD) pipelines in secure environments.
  • Analyze and evaluate emerging technologies to inform future-state architecture and capability roadmaps.
  • Represent Leidos and the Chinook Program in high-level technical exchanges, reviews, and governance boards with the customer and Intelligence Community (IC) stakeholders.
