Senior Backend Software Engineer (Go)

Join Surfshark’s VPN Engineering team as a Senior Back-end Engineer and help shape the orchestration layer of our next-generation networking platform. You’ll design and build control plane services in Go that securely manage thousands of workloads worldwide, driving APIs, rollouts, and health tracking at scale. Working alongside a senior team, you’ll tackle tough distributed systems and security challenges, making a direct impact on how our platform runs and evolves.

If you want to:

  • Design and implement the control plane services in Go that manage workloads across a large fleet;
  • Build APIs for configuration distribution, rollout coordination, and health tracking;
  • Integrate with identity systems (OIDC, mTLS, token services) for secure bootstrap and operations;
  • Work closely with other engineers to ensure smooth rollout waves, canary deployments, and automated recovery;
  • Contribute to observability: exposing service metrics, building dashboards, setting up alerts;
  • Participate in code reviews, system design, and long-term architecture planning.

    • And you can check off:

  • Experience designing and operating distributed systems (control planes, schedulers, config management, etc.);
  • Familiarity with authentication/authorization standards (OIDC, OAuth2, JWT, mTLS);
  • Experience building APIs and working with manifest-driven or declarative configuration systems;
  • Solid understanding of monitoring, metrics, and health-based rollouts.

    • Bonus points if you:

  • Have had exposure to Kubernetes-style reconciliation loops, service mesh, or large-scale rollout systems.

    • Here's the deal:

  • Growth and learning opportunities: time dedicated to learning, conferences, online learning platforms, and books for your professional development;
  • Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts, a physical coach and a gym to regular mental health checks;
  • Tools of your choice: choose technical equipment and the tools you need to do your best;
  • Community and celebrations: get ready for long-lasting traditions such as yearly workation, Friday get-togethers, various team buildings and company celebrations;
  • Convenient commuting: traveling from point A to point B can be a pain. That’s why, depending on your unique circumstances, we compensate part of your public transport costs;
  • Work-life balance: We encourage working in the office, with the possibility of up to two remote days per week. Plus, with our WFA policy, you can work from almost anywhere in the world;
  • Premium Surfshark accounts: for you, your family, and friends;
  • Gross salary: 3500 - 7200 Eur/month for the Lithuanian market. It may vary depending on your skills, experience, or location.
