Senior System Engineer (Go) - Metal Platform

Vilnius, Lithuania
Full-Time
€4.750 – €7.200 per month

TLDR

Develop Go control-plane services to orchestrate fleet-wide deployments and shape Linux boot paths, advancing security and verifiability of server infrastructure.

We're building the platform that orchestrates how software moves across our entire server fleet. You'll work in Go on the control-plane services driving deployments, and shape the Linux image and boot path that safely brings servers from power-on to running production software. If you want to:

  • Design and build Go services for fleet-wide deployment, configuration, and lifecycle management;

  • Work on the Linux image and boot path used by servers in the fleet;

  • Contribute to the cryptographic protocols and machine-attestation work behind it;

  • Help keep the system's security properties verifiable as it evolves.

    • And you can check off:

  • Strong Go and a track record of shipping production backend services;

  • Solid Linux internals: kernel boot, initramfs, networking stack;

  • Comfortable with modern cryptographic primitives and authn building blocks (mTLS, OIDC, signature schemes);

  • Security-first mindset: you think in threat models, key rotation, and blast radius.

    • Bonus points if you:

  • Have worked with hardware roots of trust or measured boot;

  • Have shipped supply-chain primitives (reproducible builds, SBOMs, artifact attestation);

  • Have used formal-methods tools to reason about protocols or 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: 4750 - 7200 Eur/month for the Lithuanian market, 22000 - 33400 PLN/month for the Polish market. It may vary depending on your skills, experience, or location.
