Senior Site Reliability Engineer (Remote)

What’s in store for you:

You’ll be solving complex challenges and maintaining our own infrastructure with 60PB+ monthly data traffic. Here are its scale and maturity in numbers:

Your day-to-day:

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 the 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 & experiences:

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 REQUIREMENTS:

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.

Please note that only the selected candidates will be contacted for further steps.
