Details

The world’s most advanced VPN, and a whole lot more.

If you’re a curious problem-solver who carves their own path, join the team behind Threat Protection Pro, the NordLynx protocol, and the fastest VPN on the planet—tools that put privacy, security, and control back in people’s hands.

Your impact is helping millions take back control of their online security, privacy, and data by crafting and maintaining the microservices that drive in-app notification delivery across NordVPN and sister products.

  • Foster smooth communication and collaboration between team members and other engineering, product, and design professionals.
  • Participate in discussions, rethink ideas, and embrace redesigns to achieve shared success.

Requirements

  • Solid system design knowledge — you know patterns, when to use them, and why.
  • Experience (significant advantage) with REST, MQTT, Kubernetes (K8s), MySQL, Redis, Kafka, VerneMQ, Docker, and microservice architecture.
