We are seeking a Subject Matter Expert (SME) Cybersecurity Architect to join our team supporting a large-scale federal modernization program. This role owns security architecture across enterprise solutions, platforms, networks, identity, mobility/endpoints, data, and cloud, bridging cybersecurity policy and controls with implementable designs, evidence, and risk decisions throughout the system lifecycle. This is a hands-on architecture role. You'll be expected to produce real security designs and see them through review, implementation, and operations, not just set policy from a distance. This is a hybrid role based out of Washington, DC. Candidates must be U.S. citizens. Key Responsibilities 1. Security Architecture & Design • Develop and assess security architectures, patterns, requirements, controls integration, trust boundaries, data flows, and identity and segmentation design. • Design logging, resilience, and operational safeguards into solution architecture. • Translate federal and agency security requirements into practical design decisions, implementation actions, and residual-risk statements. 2. Reviews & Governance • Participate in architecture compliance, technical design, engineering, security, and phase-gate reviews. • Evaluate proposed deviations and waivers, and provide risk-informed recommendations for approval. • Maintain security architecture artifacts, review findings, decisions, and risks in approved repositories, with clear traceability. 3. 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. Nice to Have • Direct federal, government, or mission-critical system security architecture experience. • CISSP, CCSP, CISM, SABSA, GIAC, cloud security, or comparable security credentials. • Experience with NIST RMF/control families, zero trust, cloud security, identity, endpoint security, segmentation, logging/SIEM, and vulnerability management. • Experience documenting security architecture views in Sparx/Prolaborate or comparable architecture/modeling tools. Benefits • 401(k) • 401(k) matching • Dental insurance • Flexible spending account • Health insurance • Life insurance • Paid time off • Professional development assistance • Referral program • Tuition reimbursement • Vision insurance
