Cross-Domain Coordination • Coordinate with solution, data, cloud/platform, network, identity, endpoint/mobility, and operations stakeholders to embed security into design from the start. • Identify design gaps, threats, vulnerabilities, technical debt, and noncompliance early in the lifecycle, and propose mitigation options. 4. Risk & Compliance • Apply federal risk management framework and security control knowledge to real design decisions. • Support authorization evidence, implementation readiness, and post-deployment validation as needed. • Produce implementable security designs, review findings, mitigations, and risk decisions that engineers can act on. 5. Communication & Advisory • Communicate security architecture decisions, tradeoffs, and residual risk clearly to engineers, architects, program managers, and Government stakeholders. • Support incident and problem learning to feed back into architecture improvements. Requirements · 12+ years of experience in cybersecurity, including significant time in security architecture or enterprise technical leadership. • Working knowledge of federal risk management, security controls, authorization, continuous monitoring, zero trust, identity, network, endpoint, cloud, application, data, and logging considerations. • Ability to interpret security requirements and produce implementable designs, review findings, mitigations, and risk decisions. • Strong communication skills, with experience engaging engineers, architects, program managers, and Government decision-makers. • U.S. citizenship required.
