Your Impact at LilaWe'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 at speed. You'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 Youll Be BuildingYou 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 systemsDeployable security designs grounded in NIST 800-53 Rev. 5, DoD Cloud SRG (IL5/IL6), and FedRAMPCore security building blocks, including:Identity, credential, and access management (ICAM)Network segmentation, trust boundaries, and secure data flowsEncryption, key management, and secrets handlingZero Trust architecture (NIST 800-207) implemented in production-not just documentedReusable security platforms and patterns, including:IAM and access controlSecrets management and key lifecycleLogging, monitoring, and detectionSecure CI/CD and Infrastructure as CodeEnterprise reference architectures supporting both FedRAMP and non-FedRAMP systemsCompliance-aware designs that minimize authorization scope through control inheritance, reuse, and standardizationAutomated compliance evidence pipelines that reduce manual effort and improve audit readinessSecurity-by-design integrations embedded into product engineering and cloud infrastructureArchitectural support for resilience and response, including threat modeling, risk assessment, incident response, and forensic readinessWhat Success Looks LikeSecurity controls are designed once and reused across applications and platformsCompliance evidence is automated, repeatable, and scalableEngineering teams adopt security patterns naturally, without frictionSecurity architecture accelerates delivery instead of slowing it downThis role is for someone who wants to build durable, reusable security architecture that scales beyond one system-and enables high-assurance cloud delivery at speed. This is not a policy-only or governance-only position.What You'll Need to SucceedYou 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 engineeringProven, hands-on delivery of FedRAMP IL5 and/or IL6 systems, from design through authorizationStrong working knowledge of:NIST 800-53 Rev. 5DoD Cloud Computing SRG (IL5/IL6)FedRAMP authorization and ATO processesCloud security architecture experience in AWS GovCloudExperience securing cloud-native platforms, including:Container orchestration (EKS, AKS, OpenShift)CI/CD pipelines and Infrastructure as CodeAbility to explain control intent and risk tradeoffs, not just map requirements to controlsAbout LilaLila Sciences is the world's first scientific superintelligence platform and autonomous lab for life, chemistry, and materials science.
