This role is framework-agnostic and vendor-informed: the ideal candidate understands that Zero Trust is a security philosophy and architectural strategy, not a single product or platform, guided by the principle of "never trust, always verify." The engineer will apply that expertise across one or more leading vendor ecosystems to deliver compliant, mission-ready ZTA solutions aligned with federal mandates including EO 14028, OMB M-22-09, NIST SP 800-207, and the CISA Zero Trust Maturity Model and Secure Access Service Edge (SASE) guidance. These responsibilities and strategies are currently shared across three teams and, as a result, are owned by none of them. Current cyber threats require aligning, consolidating, and bridging access control strategies and policies into a unified front, acting as Trust Brokers across the enterprise, so the organization can maintain a strong security posture ahead of adversaries. Must be located in the DC Metro Area as this role requires onsite and remote support., Architecture and Strategy * Lead Zero Trust Architecture assessments, gap analyses, and roadmap development for federal clients * Design and document ZTA solutions spanning all five pillars: Identity, Device, Network, Application/Workload, and Data * Translate federal ZTA mandates (EO 14028, OMB M-22-09, CISA ZT Maturity Model) into actionable implementation plans * Develop architecture artifacts including conceptual, logical, and physical ZTA diagrams using DODAF, TOGAF, or equivalent frameworks * Support integration of ZTA principles into existing enterprise architectures, hybrid cloud environments, and multi-tenant federal networks * Drive SASE convergence, consolidating network and security enforcement onto a single policy plane * Advance security posture design and real-time trust evaluation, with a focus on insider threat detection and response Implementation and Engineering * Deploy and configure Zero Trust solutions across one or more vendor platforms (see Vendor Ecosystem section below) * Own top-level Conditional Access policy design and privileged access governance in Microsoft Entra ID/M365 * Implement Identity and Access Management controls including CAC/PIV authentication, MFA, role-based access control (RBAC), and Just-in-Time (JIT) Privileged Access Management * Deliver Enterprise Identity, Credential, and Access Management (ICAM) support services, with priority focus on PIV-enabled logical access implementation across enterprise systems * Enforce device posture as a condition of every access decision, integrating SCCM, Intune, Workspace ONE (WS1), Purview, Qualys, and Palo Alto NGFW signals * Define and enforce application-layer access policy and decisions across M365, Palo Alto NGFW, Entra ID, and Workspace ONE (WS1) * Configure microsegmentation, Zero Trust Network Access (ZTNA), software-defined perimeters, and DNS security controls across the network landscape, including Palo Alto, Cisco, and wireless infrastructure * Deploy Endpoint Detection and Response (EDR) tooling and enforce device compliance policies at enterprise scale * Integrate data protection controls including classification, labeling, DLP, and encryption aligned to ZTA data pillar requirements Compliance and Authorization * Align ZTA implementations with NIST SP 800-53 Rev 5, NIST SP 800-207, DISA STIGs, and DHS CDM program requirements * Support the Risk Management Framework (RMF) lifecycle, including SSP authoring, continuous monitoring, and ATO maintenance * Document ZTA controls for system security packages, POA&Ms, and security assessment reports * Own access policy exception management, including governance workflows and audit-ready evidence documentation Client Engagement and Collaboration * Serve as a trusted ZTA advisor to federal agency stakeholders, program managers, and ISSO/ISSM counterparts * Produce executive-level briefings, technical white papers, and implementation status reports * Collaborate cross-functionally with cloud, networking, data analytics, and infrastructure teams to ensure cohesive ZTA integration, CIG's ZTA practice is solution-agnostic at the architectural level. Engineers are expected to bring deep expertise in at least one of the following vendor platforms, with cross-platform fluency strongly preferred: Vendor / Framework & Relevant Capabilities Palo Alto Networks (Prisma): Prisma Access (ZTNA 2.0), Prisma Cloud, Cortex XDR/XSIAM, NGFW policy, SD-WAN integration, threat prevention across all ZTA pillars Zscaler: Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), Zscaler Digital Experience (ZDX), cloud proxy architecture, VPN replacement, SSL inspection Microsoft Zero Trust: Microsoft Entra ID (Azure AD), Conditional Access, Intune/MEM, Microsoft Defender suite, Sentinel SIEM/SOAR, Purview data governance, M365 compliance center CISA ZT Maturity Model: Five-pillar maturity assessment (Traditional, Initial, Advanced, Optimal), cross-cutting capability mapping, agency self-assessment support, roadmap alignment to federal reporting requirements Additional Enterprise Tooling: SCCM, Workspace ONE (WS1), Qualys vulnerability management, and Cisco network/wireless fabric, supporting device posture and network segmentation enforcement across the landscape, Soltesz is growing, and we are seeking an experienced Senior Project Manager to join our Lanham office.
