Requirements

  • A bachelor's degree or equivalent experience is required.
  • Hands-on experience designing or supporting federal-grade, Zero-Trust-aligned architectures, including identity-centric access, micro-segmentation, encrypted traffic inspection, and cloud boundary protections.
  • Experience with TIC 3.0 concepts, trust zones, distributed enforcement, and cloud and mobility use cases is required.
  • Background in cloud, network, or security architecture, including AWS, Azure, hybrid networking, and segmentation.
  • Hands-on familiarity with firewalls, cloud gateways, DNS, identity and access management, API security, logging pipelines, and SIEM integrations.

  • Oversee gateway transformation, including redesign, scaling, load distribution, and modernization aligned with TIC 3.0.
  • Communicate architectural decisions, risks, and modernization strategies to VA leadership.
  • Evaluate emerging technologies, lead pilots and proofs of concept, and recommend mission-aligned adoption strategies.
  • Support escalations and critical events involving cloud networks, identity systems, boundary controls, and policy enforcement point operations.
  • Produce architecture diagrams, trust-zone definitions, policy enforcement point mappings, documentation, and compliance artifacts.
  • Mentor engineers and promote security best practices across cloud and network architecture teams.
