We are seeking a Cloud Security Architect to design, secure, and support the cloud architecture behind U.S. Space Force human capital management (HCM) modernization, the system that manages several factors such as personal, promotion, and assignment for USSF Guardians. The position initially supports a Workday-based Small Business Innovation Research (SBIR) Phase II effort and is expected to contribute to the transition toward a production program of record, subject to program award and customer requirements.

Reporting to the Program Manager, you will work with a team across cloud engineering, cybersecurity, identity management, enterprise integration, and Risk Management Framework (RMF) to deliver a secure, scalable architecture capable of supporting Department of War Impact Level 4 (IL4) requirements and successful authorization.

• Design and document secure cloud architectures for IL4 hosting in AWS Gov Cloud, covering 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 the 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 all technical outputs.

• 7+ years of cloud architecture, cybersecurity architecture, or secure enterprise systems engineering experience.
• Direct experience designing or securing Department of War (DoW) IL4/IL5 or 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.
