Cloud Security Architect - IL4 / Enterprise Integration

TOMORROW HIRE•Washington, DC

1d•$150,000 - $200,000•Hybrid

About The Position

The Cloud Security Architect will design, secure, and support the cloud architecture for U.S. Space Force human capital management (HCM) modernization. The role initially supports a Workday-based Small Business Innovation Research (SBIR) Phase II effort and is expected to contribute to a transition toward a production program of record, subject to program award and customer requirements. The role reports to the Program Manager and works across cloud engineering, cybersecurity, identity management, enterprise integration, and Risk Management Framework (RMF) to deliver a secure, scalable architecture that supports Department of War Impact Level 4 (IL4) requirements and authorization. The position focuses on IL4 cloud hosting in AWS GovCloud, secure Workday and third-party SaaS integration, identity federation, network connectivity, security monitoring, and RMF authorization support. It also evaluates the SBIR architecture against production requirements and develops scalable, supportable designs for the anticipated HCM program of record. The work arrangement is hybrid, with occasional onsite work at a government or MPX site potentially required. The primary site is the Washington, DC metropolitan area; candidates may also be based near Buckley, Patrick, Peterson, or Schriever Space Force Base. The current contract period of performance runs through contract award, with a planned pathway to a production program of record.

Requirements

7+ years of cloud architecture, cybersecurity architecture, or secure enterprise systems engineering experience.
Direct experience designing or securing Department of War (DoW) IL4/IL5 and FedRAMP High environments.
Hands-on experience with RMF and Authority to Operate (ATO) processes, including control implementation, documentation in eMASS, and assessor support.
Hands-on experience with identity federation, including CAC/PKI or PIV-based authentication, zero trust architecture, encryption, network security, and SaaS integrations.
Experience designing secure APIs, enterprise integrations, and data exchange architectures.
Ability to document technical decisions, communicate architecture risks, and collaborate across engineering and security teams.
U.S. citizenship.
DoD 8140 qualification at the required level (e.g., CISSP or CCSP), or ability to obtain it within 6 months of hire.

Nice To Haves

Experience integrating Workday or another enterprise human capital management platform.
Experience supporting U.S. Space Force or Department of the Air Force modernization programs.
Familiarity with the DoW Cloud Computing Security Requirements Guide (CC SRG), NIST SP 800-53, and applicable DISA STIGs and SRGs.
Cloud architecture or security certifications (e.g., AWS or Azure architect or security credentials), or equivalent demonstrated expertise.
Experience transitioning SBIR, prototype, or pilot capabilities into production government environments.
Experience with AWS GovCloud or Azure Government, Cloud Access Point (CAP) connectivity, and CSSP onboarding.

Responsibilities

Design and document secure cloud architectures for IL4 hosting in AWS GovCloud, including identity and access management, encryption, network security, boundary protection, and monitoring.
Develop secure integration patterns between Workday and third-party SaaS, including identity federation with CAC/PKI and DoD ICAM, APIs, data exchange, and zero trust controls.
Design IL4 network connectivity through the required Cloud Access Point (CAP) and align monitoring and incident response with the program's Cybersecurity Service Provider (CSSP).
Partner with the RMF lead to implement and document NIST SP 800-53 controls in eMASS, apply applicable STIGs and SRGs, prepare authorization evidence, support assessors, and remediate technical findings.
Evaluate the SBIR architecture against production requirements and develop scalable, supportable designs for the anticipated HCM program of record.
Collaborate with architects, platform engineers, cybersecurity specialists, subcontractors, and government technical authorities.
Apply approved AI and automation tools to improve architecture analysis, configuration validation, security documentation, and engineering efficiency, while keeping CUI and other sensitive data within approved boundaries and validating technical outputs.
