Zero Trust Engineer Mid Level

Job Description

Job Description

POSITION SUMMARY
Celestial Innovations Group (CIG) is seeking a Mid Zero Trust Engineer to support federal agency clients in the design, implementation, and sustainment of Zero Trust Architecture (ZTA) programs. 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. 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.

Must be located in the DC Metro Area as this role requires onsite and remote support.

KEY RESPONSIBILITIES
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

Implementation and Engineering

• Deploy and configure Zero Trust solutions across one or more vendor platforms (see Vendor Ecosystem section below)
• Implement Identity and Access Management controls including CAC/PIV authentication, MFA, role-based access control (RBAC), and Just-in-Time (JIT) Privileged Access Management
• Configure microsegmentation, Zero Trust Network Access (ZTNA), software-defined perimeters, and DNS security controls
• 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

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

VENDOR ECOSYSTEM EXPERIENCE
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

REQUIRED QUALIFICATIONS
Experience

• 5+ years of experience in cybersecurity engineering, network security, or IT infrastructure roles
• 2+ years of hands-on experience designing or implementing Zero Trust Architecture in an enterprise or federal environment
• Demonstrated understanding of ZTA concepts across all five pillars per NIST SP 800-207 and the CISA Zero Trust Maturity Model
• Experience supporting federal government clients or DoD/civilian agency environments

Technical Skills

• Proficiency in at least one of the following: Palo Alto Prisma, Zscaler, or Microsoft Zero Trust stack
• Identity and access management: Entra ID, Active Directory, LDAP, PKI, MFA, PAM tooling
• Network security: microsegmentation, ZTNA, DNS security, SD-WAN, next-generation firewall policy
• Endpoint security: EDR/XDR deployment and management, device compliance policy enforcement
• Cloud environments: Azure, AWS, or hybrid cloud architectures with ZTA overlay
• Familiarity with SIEM/SOAR platforms (Microsoft Sentinel, SumoLogic, Google SecOps, or equivalent)

PREFERRED QUALIFICATIONS

• Active certifications in one or more ZTA vendor platforms: PCCSE, PCNSE, Zscaler ZCCA-IA or ZCCA-PA, Microsoft SC-100 (Cybersecurity Architect Expert)
• Additional certifications: CISSP, CISM, CompTIA Security+, Cloud+ or relevant AWS/Azure security certifications
• Familiarity with RMF processes: NIST SP 800-37, SSP authoring, ATO package preparation
• Experience with ServiceNow, Salesforce, or IT service management tooling in a federal context
• Multi-vendor ZTA integration experience (e.g., combining Palo Alto and Zscaler capabilities within a single architecture)
• Familiarity with post-quantum cryptography standards (FIPS 203/204/205) and their ZTA implications

Flexible work from home options available.
