Qualifications

• Active TS/SCI clearance with ability to obtain CI Polygraph.
• Experience designing, evaluating, or fielding systems operating with denied, disrupted, intermittent, or limited connectivity.
• Experience developing mission or enterprise architectures that support disconnected operation and eventual synchronization.
• Ability to translate operational constraints into technical requirements, architectural decisions, and testable performance criteria.
• Understanding of distributed systems concepts, including consistency, replication, caching, and failure recovery.
• Experience addressing identity, authentication, authorization, or credential dependencies when central services are unavailable.
• Understanding of security implications of stale attributes, revocation delays, and unavailable policy or key services.
• Experience assessing bandwidth, latency, and network availability constraints on applications.
• Experience creating architectural documentation, roadmaps, and implementation plans.
• Ability to explain tradeoffs and residual risks to Government decision-makers.

Responsibilities

• Develop DDIL strategies, architectures, and roadmaps for mission apps and security services.
• Define operational scenarios, connectivity constraints, mission priorities, and degraded service levels.
• Translate scenarios into requirements for autonomy, bandwidth, latency, and recovery.
• Architect local identity and attribute services, including virtual directories and caching.
• Plan for cached attribute freshness, credential expiry, revocation awareness, and offline operation.
• Evaluate access control tradeoffs for offline or degraded operation.
• Design synchronization and reconnection approaches for conflicting updates and data restoration.
• Define dependencies among apps, identity providers, policy services, and key management.
