You will partner closely with Engineering, System Administration, and Operations teams.

Key Responsibilities:

Enterprise DDI Architecture & Compliance

• Design and maintain authoritative and recursive DNS architectures that

signing/validation and chain-of-trust with DS records.

• Operationalize

guidance for secure DNS deployment (protective DNS, encrypted DNS protocols such as DoT/DoH/DoQ, logging/forensics, QNAME minimization) across enterprise DNS roles (authoritative servers, resolvers, zone administration).

• Ensure compliance with

and blocking unauthorized external resolvers.

• Align with

(mitigate internet-exposed management interfaces).

• Drive

• Serve as technical lead for large-scale DDI environments, overseeing secure configurations, automation, availability, and performance across centers. (Role scope mirrors enterprise-class environments consistent with NASA's operational scale.)
• Implement protective controls and monitoring to detect, log, and investigate DNS misuse; integrate with SIEM/SOAR for

per 800-81r3.

• Maintain continuous vulnerability management aligned to

and reporting expectations; coordinate remediation timelines and control validation.

• Secure networked

metrics and RSO coordination.

• Ensure

• Administer top-level allocations and growth planning for IPv4/IPv6

, consistent with

• Evaluate and integrate DDI platform capabilities (e.g., encrypted DNS with PDNS, DNSSEC automation, DHCPv6 prefix delegation, IPAM APIs), and champion modernization aligned with Zero Trust and federal CDM initiatives.

(DDI) services, with demonstrated authority in secure DNS architectures (DNSSEC, validating resolvers, signed zones, DS management). (Aligned to NIST SP 800-53 SC-20/SC-21.)

• Hands-on implementation of

practices: protective DNS, encrypted DNS (DoT/DoH/DoQ), secure recursive resolvers, authoritative hardening, and comprehensive DNS logging/forensics.

• Practical experience meeting

and enforce endpoint, cloud, and SASE/SSE DNS policies.

• Proven track record implementing federal

milestones.

• Familiarity with

DNSSEC requirements and secure delegation processes for federal domains.

• Knowledge of

• Experience supporting or coordinating with Root Server Operators

metrics submissions.

• Prior leadership in environments with

end-to-end (endpoint, internal resolvers, egress to PDNS, cloud).

• Demonstrated capability to manage

(including HSTS/HTTPS and STARTTLS hardening).

• Experience integrating DDI with

• Strong understanding of

broader control families (SC, SI, AU) and mapping to DNS/Network operations.
