Contractor - Enterprise Technology Systems

Hybrid - HDQ/GPO

The Zero Trust Security Engineer is responsible for driving the implementation of Zero Trust security rules, including formal requests to firewall teams, ongoing coordination, validation of changes, and post implementation verification.
This role is execution focused and serves as the single point of accountability for ensuring Zero Trust rules are implemented correctly, completely, and auditable across firewall and security platforms.

Key Responsibilities
Rule Implementation & Coordination
Translate Zero Trust analysis outputs into formal firewall and security rule requests.
Submit detailed implementation requests to firewall teams, including:
o Source identities (users, groups, roles)
o Destination applications, addresses, and services
o Required ports, protocols, and application IDs
Ensure requests meet firewall team standards and contain all required technical details.
Cross Team Execution
Act as the primary liaison between Zero Trust, IAM, firewall engineering, and application teams.
Track firewall requests from submission through completion.
Resolve implementation questions, clarifications, or discrepancies with firewall engineers.
Validation & Verification
Validate that implemented firewall rules exactly match approved Zero Trust requirements.
Perform post implementation testing to confirm:
o Authorized access works as expected
o Unauthorized access is blocked
Identify and remediate misconfigurations, partial implementations, or policy drift.
Audit & Lifecycle Management
Ensure all implemented rules are properly tagged, documented, and traceable to application and Zero Trust requirements.
Maintain implementation records for audit, compliance, and reporting.
Support ongoing refinement of Zero Trust rules as application access requirements evolve.
