Senior Post-Quantum Cryptography (PQC) / Cryptography Architect (2026-0213)

Acclaim Technical Services, founded in 2000, is a leading cyber operations, intelligence solutions and operations, network infrastructure, engineering and business enablement and enterprise operations company supporting a wide range of U.S. Federal agencies. We are an Employee Stock Ownership Plan (ESOP) company, which is uncommon within our business sector. We see this as a significant strength, and it shows: ATS is consistently ranked as a top workplace among DC area firms and continues to grow. We are actively hiring a Senior Post-Quantum Cryptography (PQC) / Cryptography Architect with a TS/SCI clearance to support ATS's post-quantum cryptography readiness capability and customer engagements in Northern Virginia. In this role, you will lead the technical architecture for identifying quantum-vulnerable cryptography, developing authoritative cryptographic inventories and Cryptographic Bills of Materials (CBOMs), assessing mission and system risk, evaluating crypto-agility, and developing defensible PQC migration strategies. You will work across enterprise applications, infrastructure, networks, cloud environments, security services, PKI, data platforms, and mission systems to translate cryptographic discovery evidence into prioritized and executable migration decisions. The ideal candidate combines deep applied cryptography expertise with enterprise architecture, cybersecurity, systems engineering, and the ability to communicate complex cryptographic risk to both technical and executive Federal stakeholders. Key Responsibilities Lead cryptographic discovery, inventory, assessment, and migration architecture across complex Federal and national-security environmentsDevelop and maintain authoritative cryptographic inventories and CBOMs, including algorithms, protocols, certificates, keys, cryptographic libraries, hardware dependencies, system owners, mission dependencies, and migration statusIdentify the specific quantum-vulnerable cryptographic components and dependencies within applications, systems, protocols, infrastructure, and data flowsEvaluate discovery evidence from source code, binaries, configuration files, network protocols, certificates, PKI, KMS/HSM platforms, cryptographic libraries, cloud services, vulnerability/security tooling, and other available data sourcesAssess crypto-agility and quantum risk based on algorithm usage, mission criticality, data sensitivity and longevity, system dependencies, interoperability, operational constraints, and migration complexityDevelop mission-prioritized PQC migration roadmaps, sequencing systems and dependencies based on technical risk and operational impactDesign target-state PQC and hybrid migration architectures using applicable NIST standards and Government-approved cryptographic requirementsEvaluate and recommend migration approaches for PKI, TLS, digital signatures, key establishment, software libraries, infrastructure services, KMS/HSM environments, and other cryptographic dependenciesDevelop architecture diagrams, migration patterns, risk assessments, technical decision documents, implementation guidance, and executive-level migration plansWork with application owners, infrastructure teams, security organizations, enterprise architects, mission stakeholders, and vendors to validate findings and develop practical migration approachesSupport proofs of concept, technical validation, implementation planning, and migration execution where requiredAssess commercial and Government cryptographic-discovery and migration tools and integrate them into a tool-agnostic assessment methodology rather than depending on a single proprietary platformBrief Federal technical leaders, CISOs/CIOs, program executives, mission owners, and other senior stakeholders on cryptographic exposure, migration priorities, dependencies, and recommended actionsMaintain traceability from discovered cryptographic components through risk assessment, remediation decision, target architecture, and migration status Minimum Requirements Active TS/SCI clearanceSignificant applied experience
