Principal / Senior Principal, Security Architect

San Francisco, CA USA

We’re looking for a Principal Security Architect to lead the security architecture for cloud applications operating at FedRAMP IL5 and IL6, while also shaping enterprise-wide security architecture and engineering.

This is a hands‑on leadership role—your work will directly enable secure product delivery ’ll lead the design, implementation, and authorization of FedRAMP IL5/IL6 systems, then scale that success by building reusable security platforms, patterns, and practices across the organization.

What You'll Be Building

You will define and deliver secure cloud architectures that meet the highest federal standards while staying practical and engineer friendly. Your designs will become the foundation for multiple systems and scale across teams and environments.

• FedRAMP IL5 / IL6 security architectures co‑owned with Application Architects and applied across multiple systems
• Deployable security designs grounded in NIST 800‑53 Rev. 5, DoD Cloud SRG (IL5/IL6), and FedRAMP
• Core security building blocks, including:
  • Identity, credential, and access management (ICAM)
  • Network segmentation, trust boundaries, and secure data flows
  • Encryption, key management, and secrets handling
• Zero Trust architecture (NIST 800‑207) implemented in production—not just documented
• Reusable security platforms and patterns, including:
  • IAM and access control
  • Secrets management and key lifecycle
  • Logging, monitoring, and detection
  • Secure CI/CD and Infrastructure as Code
• Enterprise reference architectures supporting both FedRAMP and non‑FedRAMP systems
• Compliance‑aware designs that minimize authorization scope through control inheritance, reuse, and standardization
• Automated compliance evidence pipelines that reduce manual effort and improve audit readiness
• Security‑by‑design integrations embedded into product engineering and cloud infrastructure
• Architectural support for resilience and response, including threat modeling, risk assessment, incident response, and forensic readiness

What Success Looks Like

• Security controls are designed once and reused across applications and platforms
• Compliance evidence is automated, repeatable, and scalable
• Engineering teams adopt security patterns naturally, without friction
• Security architecture accelerates delivery instead of slowing it down

This role is for someone who wants to build durable, reusable security architecture that scales beyond one system—and enables high‑assurance cloud delivery s is not a policy‑only or governance‑only position.

What You'll Need to Succeed

You bring deep, hands‑on experience designing and delivering secure cloud systems in highly regulated environments. You’re comfortable translating complex requirements into scalable architecture and guiding teams through delivery.

• 8+ years in cybersecurity, security architecture, or security engineering
• Proven, hands‑on delivery of FedRAMP IL5 and/or IL6 systems, from design through authorization
• Strong working knowledge of:
  • NIST 800‑53 Rev. 5
  • DoD Cloud Computing SRG (IL5/IL6)
  • FedRAMP authorization and ATO processes
• Cloud security architecture experience in AWS Gov Cloud
• Experience securing cloud‑native platforms, including:
  • Container orchestration (EKS, AKS, Open Shift)
  • CI/CD pipelines and Infrastructure as Code
• Ability to explain control intent and risk tradeoffs, not just map requirements to controls
