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. You're the person others rely on when the architecture needs rethinking or a service needs to go from zero to globally deployed.

- Design and operate on-demand, globally distributed backend services
- 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
Core Requirements
- Designing and operating globally distributed systems
- 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
Bonus Points For
- Kubernetes in production environments
- SaltStack (used heavily internally)
- Advanced networking - BGP, anycast, tunneling, traffic engineering

- GitLab
- Nexus
- Consul
