Warsaw / Krakow

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? Helping millions take back control of their online security, privacy, and data.

NordVPN protects millions of users daily through a global edge infrastructure spanning thousands of servers across dozens of countries. The platform engineering team builds and operates the internal backend services that make this possible.

We're looking for a Staff Site Reliability Engineer (SRE) to design, build, operate, and improve these systems. This is a high-ownership role — you'll architect solutions, ship them to production.

Make architectural decisions on how internal services integrate and scale

Manage the full lifecycle: planning, implementation, monitoring, incident response, postmortems

Maintain and improve infrastructure tooling and automation

Contribute to engineering standards, documentation, and operational maturity

Evaluate and integrate AI tooling (LLMs, Claude Code, model integrations) into engineering workflows

Systems architecture - service communication, data flow, resilience patterns

Linux administration at scale (systemd, kernel tuning, debugging production systems)

Docker - building, shipping, and running containers in production

Databases - PostgreSQL, MySQL, Redis, OpenSearch, VictoriaMetrics

Web servers, load balancing, and failover (Nginx, HAProxy, or similar)

Working with dedicated/bare-metal hardware

Python or another scripting/programming language

Familiarity with AI/LLM tooling and practical application in engineering workflows
