Job Description & How to Apply Below
Securetron is seeking a  Post‑Quantum Research & PKI Cryptography Engineer  to lead research, prototyping, and implementation of  quantum‑resistant cryptographic workflows  within our 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 .

Key Responsibilities

PQC Algorithm Research  — Evaluate NIST‑selected PQC algorithms (ML‑KEM, ML‑DSA) and their applicability to enterprise PKI and certificate issuance.

Hybrid Crypto Design  — Prototype hybrid classical/PQC certificate chains, key exchange mechanisms, and dual‑layer signing workflows.

PKI Integration  — Implement PQC‑ready certificate templates, CSR formats, and enrollment flows across Securetron’s PKI Trust Manager.

Crypto‑Agility Frameworks  — Design mechanisms enabling rapid algorithm rotation, policy enforcement, and automated migration.

CBOM Generation  — Build tooling to generate and validate Cryptographic Bills of Materials for enterprise environments.

Standards Alignment  — Track NIST, ETSI, IETF, CAB Forum, and browser‑root program requirements.

Performance & Security Testing  — Benchmark PQC algorithms, validate interoperability, and assess operational impact.

Developer Enablement  — Produce documentation, reference implementations, and internal guidance for engineering teams.

Required Qualifications

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.

Preferred Qualifications

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 You’ll Work On

PQC‑ready certificate issuance pipelines

Hybrid negotiated dual‑layer (HNDL) signing

PQC‑enabled micro‑agents for distributed certificate discovery

Automated crypto‑agility policy engines

PQC migration playbooks for enterprise customers

Why Securetron

Work at the forefront of post‑quantum cryptography and PKI automation

Build infrastructure used by enterprises preparing for the 47‑day TLS era

Shape the future of trust automation across cloud, on‑prem, and hybrid environments
