We’re a team of 500+ professionals who develop cutting-edge proxy and web data scraping solutions for thousands of the world’s best known businesses, including Fortune 500 companies.
What’s in store for you:
You’ll be solving complex challenges and maintaining our own infrastructure.

In this role, you’ll:

  • Own and evolve Webshare's production infrastructure - lead the migration from Docker Swarm to Kubernetes (or hybrid K8s + Ansible).
  • Maintain high availability across hundreds of servers and ~50 services.
  • Drive observability in cooperation with development team.
  • Establish and enforce IaC practices, CI/CD pipeline reliability, and change management processes.
  • Participate in the on-call rotation alongside backend developers.
  • Respond to and lead incident resolution, run post-mortems and drive systematic remediation.
  • Contribute platform tooling that improves developer experience and reduces infrastructure toil.
  • Keep backend engineers informed and capable — no silos, shared infrastructure ownership.

    • Your skills & experience:

  • Have built and operated highly available infrastructure at comparable scale — hundreds of servers, dozens of services, real production load.
  • Hands-on K8s in self-hosted / bare-metal environments.
  • Confident with Infrastructure as Code.
  • Have owned CI/CD pipelines end-to-end (GitLab CI or equivalent).
  • Have been on call in a production environment.
  • Proactive— surfaces problems before being asked, keeps the team informed without prompting.
  • Scripting and development skills.

    • Nice to have:

  • Led at least one major infrastructure migration - planned, executed, and stabilised it.
  • Python and/or Go familiarity - backend is Python, edge services are Go.
  • Exposure to proxy, networking-heavy infrastructure.
  • Previous experience in a small team where developers shared infrastructure responsibility.
  • Familiarity with edge clusters or split compute/edge architectures.

    • Salary & Benefits:

  • Gross salary: 5800 eur/month - 7400 eur/gross + quarterly KPI-based performance bonus. Keep in mind that we are open to discussing a different salary based on your skills and experience.
  • Growth & Learning: 40+ internal learning options, external conferences, mentorship, and year-round knowledge-sharing.
  • Health & Well-being: Private health insurance, gym allowance and a wellness app.
  • Celebration & Community: Team events, an overseas workation and plenty of ways to mark milestones together.
