Company Description QNNX builds next-generation security solutions for the quantum era, focusing on post-quantum cryptography, quantum-secure communication, and quantum cyber-defense. The company delivers enterprise-grade products such as QNN Sentinel for NIST-ready PQC, QNN QuantumShield for quantum threat simulation and risk analysis, and QNN AuroraNet for quantum-secure networking. QNNX also offers TrueQ and LightLink hardware modules that provide quantum-grade randomness and secure optical links. Serving enterprises, governments, and cloud providers, QNNX helps protect critical data and infrastructure against emerging quantum threats. The mission is to make the world quantum-safe before large-scale quantum computers can compromise today’s encryption.
Role Description This is a full time, on-site role based in the Greater Delhi Area for a Post-Quantum Cryptography Developer. The developer designs, implements, and optimizes post-quantum cryptographic algorithms and protocols across QNNX’s product suite, with a focus on secure, high-performance back-end systems.



Daily responsibilities include translating cryptographic specifications into robust software, integrating PQC libraries and APIs, and conducting code reviews to maintain security and reliability. The role involves collaborating with security researchers and engineering teams, contributing to threat modeling and performance benchmarking, and preparing technical documentation and implementation guides. The developer also participates in testing, debugging, and maintaining production-grade systems that align with emerging standards such as NIST PQC recommendations.
