Post‑Quantum Research & PKI Cryptography Engineer

As a Post-Quantum Research & PKI Cryptography Engineer at Securetron, you will lead research, prototyping, and implementation of quantum-resistant cryptographic workflows within the PKI automation stack. You will work across PQC algorithms, hybrid key exchange, certificate formats, CBOM generation, and crypto-agility frameworks to ensure customers can transition safely and efficiently. This role blends deep cryptographic research, hands-on engineering, and standards-driven implementation.

What you'll do

• Evaluate NIST-selected PQC algorithms (ML-KEM, ML-DSA) and their applicability to enterprise PKI and certificate issuance
• Prototype hybrid classical/PQC certificate chains, key exchange mechanisms, and dual-layer signing workflows
• Implement PQC-ready certificate templates, CSR formats, and enrollment flows across Securetron's PKI Trust Manager
• Design mechanisms enabling rapid algorithm rotation, policy enforcement, and automated migration
• Build tooling to generate and validate Cryptographic Bills of Materials for enterprise environments
• Track NIST, ETSI, IETF, CAB Forum, and browser-root program requirements
• Benchmark PQC algorithms, validate interoperability, and assess operational impact
• Produce documentation, reference implementations, and internal guidance for engineering teams

What you bring

• A strong background in applied cryptography, PKI, or certificate lifecycle management
• Experience with PQC algorithms, lattice-based cryptography, or hybrid key exchange
• Hands-on experience with OpenSSL, BoringSSL, Azure Key Vault, HSMs, or certificate authorities
• Proficiency in Go, Python, Rust, or C/C++ for cryptographic prototyping
• Familiarity with X.509, CSR formats, OCSP, CRLs, and certificate automation
• Understanding of NIST PQC standardization, IETF drafts, and CAB Forum requirements

Nice to have

• Experience implementing ML-KEM, ML-DSA, or hybrid certificate chains
• Contributions to cryptographic libraries or standards bodies
• Experience with enterprise PKI, IoT identity, or large-scale certificate automation
• Knowledge of secure enclaves, HSM integration, or key-management workflows

What we offer

• Competitive compensation and equity
• Growth opportunities
