Solutions Architect

Description

NEEDED: DDI Architect (DNS / DHCP / IPAM) - NASA

About the Role

NASA seeks a seasoned

DDI Architect

to lead the architecture, design, engineering, and lifecycle management of enterprise-scale

DNS, DHCP, and IP Address Management (IPAM)

services across Corporate and Mission networks. The role will drive secure, resilient name resolution aligned to federal requirements-including

NIST SP 80053 controls for secure name/address resolution (SC20, SC21) ,

NIST SP 80081r3 DNS security guidance , and

CISA encrypted/protective DNS mandates -and support NASA's mission-critical DNS operations, which include participation as a

Root Server Operator (Eroot) .

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

implement NIST SP 80053 SC20 (authoritative)

and

SC21 (recursive/caching) -including

DNSSEC

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

Operationalize

NIST SP 80081r3

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

CISA's Encrypted DNS Implementation Guidance

and Zero Trust objectives, including routing

egress resolution via CISA Protective DNS (PDNS)

and blocking unauthorized external resolvers.

Align with

CISA Binding Operational Directives (BODs) - BOD 1801

(DMARC/HSTS/STARTTLS),

BOD 2201

(KEV remediation timelines),

BOD 2301

(asset visibility/vulnerability detection), and

BOD 2302

(mitigate internetexposed management interfaces).

Drive

IPv6first

strategy per

OMB M2107

(native IPv6 for public services, IPv6only milestones) and maintain dualstack transition hygiene for DNS, DHCPv6, and IPAM.

Operations, Risk Reduction & Lifecycle Management

Serve as technical lead for largescale DDI environments, overseeing secure configurations, automation, availability, and performance across centers.

(Role scope mirrors enterpriseclass environments consistent with NASA's operational scale.)

Implement protective controls and monitoring to detect, log, and investigate DNS misuse; integrate with SIEM/SOAR for

forensics and incident response

per 80081r3.

Maintain continuous vulnerability management aligned to

CISA's KEV catalog

and reporting expectations; coordinate remediation timelines and control validation.

Secure networked

management interfaces

(e.g., DNS appliance UI/API, DHCP consoles, IPAM admin) by removing public exposure or enforcing

Zero Trust policy enforcement points

in accordance with

BOD 2302 .

Govern DNS emailrelated configurations (SPF/DKIM/DMARC) to meet

BOD 1801

requirements and support NASA Email Architecture.

Root & .gov Domain Stewardship

Participate in operations for

E.rootservers.org (Eroot)

as applicable-supporting authoritative root zone service, anycast deployments, and adherence to

RSSAC002

metrics and RSO coordination.

Ensure

.gov

domain compliance (DNSSEC signing, secure delegation) per federal directives and NIST guidance.

IP Address Governance

Administer toplevel allocations and growth planning for

IPv4/IPv6 , consistent with

ARIN

policies and best practices (aggregation, RPKI, reverse DNS hygiene).

Automation & Modernization

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.

Minimum Qualifications:

Bachelor's degree and 10+ years of experience, or an Associate's degree and 15+ years of experience designing and operating enterprise

DNS/DHCP/IPAM

(DDI) services, with demonstrated authority in secure DNS architectures (DNSSEC, validating resolvers, signed zones, DS management).

(Aligned to NIST SP 80053 SC20/SC21.)

Handson implementation of

NIST SP 80081r3

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

Practical experience meeting

CISA's Encrypted DNS Guidance

and

PDNS

integration; ability to

prevent unauthorized DNS traffic

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

Proven track record implementing federal

BODs

(1801, 2201, 2301, 2302) within large environments, including KEVdriven patch prioritization and Zero Trust controls for management interfaces.

IPv6

expertise: DNS over IPv6, DHCPv6, IPAM for IPv6, and strategic migration compliant with

OMB M2107

milestones.

Familiarity with

.gov

DNSSEC requirements and secure delegation processes for federal domains.

Knowledge of

ARIN

policies (NRPM), address planning/aggregation, and registry hygiene (WHOIS/POC validation, RPKI, reverse DNS).

Preferred Qualifications:

Experience supporting or coordinating with

Root Server Operators ; familiarity with

Eroot

anycast operations and

RSSAC002

metrics submissions.

Prior leadership in environments with

protective DNS

and

encrypted DNS

endtoend (endpoint, internal resolvers, egress to PDNS, cloud).

Demonstrated capability to manage

DMARC/SPF/DKIM

deployments at scale per

BOD 1801

(including HSTS/HTTPS and STARTTLS hardening).

Experience integrating DDI with

asset discovery and vulnerability enumeration

programs per

BOD 2301 ; evidence of KEV remediation workflows.

Strong understanding of

NIST SP 80053 Rev.5

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

Background with

ARIN

IPv6 allocations, ASN operations, and address governance at federal scale.

Clearance requirements:

U.S. Citizenship is required.

Ability to obtain and maintain a Public Trust.
