Quantum Cryptography Research Engineer

About the role

AllSecureX is one of very few teams in India shipping production-grade NIST-standardized post-quantum cryptography. As a Quantum Cryptography Research Engineer, you will sit at the boundary between research papers and production code — implementing primitives, breaking your own implementations, and turning state-of-the-art schemes into auditable, fast, side-channel-resistant libraries.

Responsibilities: Implement and harden ML-KEM, ML-DSA, SLH-DSA, Falcon, and hybrid constructions in Rust, C, and assembly. Design hybrid protocols. Build test vectors, fuzzing harnesses, KAT runners. Conduct security analysis — timing, constant-time verification. Track NIST PQC standardization and IETF drafts.

Requirements: 4+ years implementing cryptography in production, or equivalent academic research with shipped code. Strong number theory / lattice / hash-based crypto foundation. Hands-on Rust, modern C, or C++. Constant-time programming. Familiarity with FIPS 203/204/205.
