Principal Cryptography & PKCS#11 Systems Engineer
Join the engineering team building hardened digital infrastructure, zero-trust cryptographic platforms, and high-velocity developer tools.
Role Overview
Architect and lead our cryptographic hardware token signing engines, native PKCS#11 bridge runtimes, and digital signature infrastructure. Work directly at the intersection of native OS drivers (Windows CryptoAPI/CNG, macOS CryptoTokenKit, Linux PCSCLite) and enterprise digital identity.
Key Requirements & Qualifications
- ✓ 10+ years of software engineering focusing on applied cryptography, PKI, and native systems programming.
- ✓ Deep expertise with PKCS#11 v2.40/v3.0 specifications, X.509 certificates, and PDF digital signature standards (PAdES, ISO 32000-2).
- ✓ Proficiency in C/C++, Rust, or Node/Go native addons communicating with smart card tokens (eMudhra, HYP2003, ePass2003, YubiKey).
- ✓ In-depth knowledge of cryptographic algorithms: RSA-PSS, ECDSA (secp256r1/ed25519), AES-GCM, and Post-Quantum Cryptography (ML-KEM/ML-DSA).
- ✓ Experience in secure token driver lifecycle management, PIN pinpad security, and OS-level smartcard daemons.
