Senior Site Reliability Engineer (VPN Engineering)

Surfshark's VPN runs on thousands of servers worldwide, from the bare-metal infrastructure up, and the VPN Engineering team keeps every layer fast and dependable. We're looking for a Senior SRE to keep that global infrastructure resilient, secure, and high-performing at scale. You'll automate the deployment and management of a distributed fleet, sharpen observability and anomaly detection, and work shoulder to shoulder with software engineers on the backbone of an always-on service. This is a hands-on role for someone who treats reliability as an engineering discipline, not a fire drill, and enjoys large-scale automation, Linux networking, incident response, and performance tuning in complex production environments.

If you want to

• Automate and scale the deployment of thousands of VPN servers across a global fleet, and design out single points of failure;
• Build reliable monitoring, logging, and anomaly detection that catches issues before they become incidents;
• Troubleshoot complex issues across Linux systems, networking, VPN protocols, and proxy layers;
• Reduce repetitive manual work with automation and internal tooling, from scripts to n8n workflows and Jira integrations;
• Partner with software engineers to optimize the infrastructure and improve tooling, CI/CD, and reliability processes;
• Lead incident response, postmortems, disaster recovery readiness, and long-term performance work.

And you can check off

• Proven experience in SRE or similar roles, with real ownership of production-critical systems at scale;
• Strong Linux systems and networking knowledge, including DNS, VPNs, routing, firewalls, and proxies;
• Solid experience with Ansible and infrastructure automation in production, and scripting skills (Bash/Python) for operational automation;
• Experience with monitoring, logging, and troubleshooting performance and reliability issues at scale;
• Familiarity with GitLab CI/CD, incident management, disaster recovery, and secure infrastructure practices;
• Comfort using AI tools (Claude, Cursor, GitHub Copilot) to reduce manual work, and the judgment to check their output for security and performance.

Bonus points if you

• Have experience with bare-metal provisioning and network boot (iPXE/PXE), hardware lifecycle, and out-of-band management;
• Have coordinated with hosting or colo providers through remote-hands and provider APIs;
• Have operated other latency-sensitive, globally distributed services, or driven cross-team architecture decisions.

• Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts with a physical coach and sports card to health insurance and regular mental health checks;
