About The Position

In the role of ICS Security Architect, you will be responsible for supporting regulated cloud, SaaS, federal enclave, and high-compliance architecture priorities. Secondary support may include corporate and enterprise security architecture initiatives as business priorities require, consistent with the position's responsibility to advance Signature's security posture across cloud, on-premises, hybrid, and SaaS environments. Lead security architecture planning, design recommendations, and implementation guidance for regulated SaaS solutions, federal cloud environments, high-compliance enclaves, and hybrid/on-premises deployments. Define authorization boundaries, trust zones, data flows, interconnections, and inheritance. Translate FedRAMP Moderate/High, NIST, CMMC, HIPAA, FISMA, FIPS, and other applicable security requirements into secure designs, standards, implementation guidance, and evidence. Design IAM, least privilege, passwordless, PIV/CAC, privileged/service access, and federal integrations. Define and recommend FIPS-aligned cryptography, PKI, key/secret management, TLS/mTLS, and encryption patterns. Establish secure Azure, Azure Government, on-premises, hybrid, and multi-cloud patterns. Design reusable security architecture patterns that can be adapted across customer-managed, company-managed, SaaS, cloud-hosted, on-premises, and hybrid deployment models. Evaluate deployment models, shared-responsibility boundaries, authorization boundaries, inherited controls, customer-managed responsibilities, and interconnection risks to ensure security requirements are clearly defined and supportable. Lead threat modeling, security design reviews, risk assessments, and development of security architecture artifacts. Embed SAST/SCA/DAST, SBOM, secrets, IaC, container, and release gates into DevSecOps. Define logging, SIEM, audit, continuous monitoring, vulnerability management, incident response, and POA&M requirements in coordination with responsible operational teams. Develop SSPs, control narratives, diagrams, interconnections, standards, and evidence. Support SaaS, federal, corporate, and enterprise security architecture initiatives as business priorities require, with primary focus on regulated technology environments and high-compliance architecture needs. Assess vendor, contractor, supply-chain, and shared-responsibility risk; recommend action.
