Company Description Qnu Labs is India's pioneer in quantum cryptography, offering the only commercially ready quantum-safe security products in the country. We are a global leader in data security, protecting critical information against the immense threats posed by the quantum computing era. Our excellence has been recognized with the Defence Innovation Award (2023) and the National Technology Award (2022).

We are building Qshield, a full-stack quantum safe security platform that combines advanced cryptography, quantum-grade hardware, and a robust integration layer. Qshield helps enterprises, defense organizations, and critical infrastructure operators seamlessly adopt quantum-safe technologies while maintaining crypto-agility. Join us to work with some of the best engineers and physicists in the world as we build the cryptographic infrastructure of the future.

Objective   We are looking for a   Network Security & Implementation Expert   to lead the solution design, engineering, and technical integration of QNu’s Quantum security products. While you will support technical demonstrations, your primary focus will be   hands-on network engineering  , architecture design, and ensuring the successful deployment of our products in complex customer environments.
Responsibilities    Network Engineering & Configuration:
Perform hands-on configuration of routers, L2/L3 switches, and VPN gateways to establish secured, stable connectivity between customer sites and QNu platforms.
Implementation & Deployment:
Lead the full technical lifecycle—from Proof of Concept (PoC) to final Go-Live—integrating QNu’s portfolio into diverse Enterprise IT environments (MPLS, SD-WAN, On-prem/Cloud).
Solution Design & Architecture:
Design secure network overlays and develop configurations, rules, and policies that align with customer security requirements and best practices.
Troubleshooting & Support:
Act as the technical subject matter expert (SME) for deep-dive troubleshooting of network flows and protocols during implementation and post-sales support.
Collaboration & Documentation:
Work closely with Engineering to refine products based on field data, while maintaining detailed technical documentation and diagrams for every engagement.

Skills & Experience Requirements    Network Security Expertise:
Strong hands-on experience in implementing Network security solutions (Firewalls, WAF, IPS/IDS) and a deep understanding of network flows, protocols, and   cryptography  .
Key Security Concepts:
Familiarity with   PKI (Public Key Infrastructure)  , Encryption standards (AES), and digital certificates.
Hands-on Configuration:
Mandatory skills in configuring Routers, L2/L3 Switches, and   IPsec/SSL VPNs   to facilitate seamless product integration.
Cloud & Virtualization:
Experience deploying solutions on AWS/Azure/GCP, or utilizing Kubernetes/Docker technologies is preferred.
Technical Tools:
Proficiency with Linux platforms (Red Hat/Ubuntu) and scripting (Python/Bash) for automation, as well as Traffic Visualization platforms for real-time demos.

Preferred Qualifications    Bachelor's degree   in Computer Science or equivalent.
10+ years of experience   in Network Engineering, Infrastructure Architecture, or Technical Implementation.

Certifications:

CISSP, CCSP, or CCIE/CCNP preferred.
Bonus points for cloud security certifications (AWS Certified Solutions Architect, Azure Security Engineer).
