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:

- 6PB+ Ceph storage

- 60PB+ monthly data traffic through our systems

- 300k+ service requests/sec processed

- 500k+ Kafka messages/sec streamed

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 a 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.
