Qualifications

• 3+ years of hands‑on experience with cloud and Linux infrastructure in production (web products or similar).
• Practical AWS experience: you can operate and troubleshoot core services, networking and permissions.
• Confident with Docker: runtime, resources, logs and health checks.
• Experience with Ansible for repeatable, idempotent configuration.
• Monitoring and logging with Grafana and ELK — you know the difference between a signal and noise.
• Scripting in Python and/or Bash to automate operational work, with safety checks built in.
• MySQL in high‑availability setups: backups, restores, replication and failover.
• A safety‑first approach to production changes: plan, validate, roll back and escape when needed.
• Ownership of what you run after it ships, plus clear written and spoken communication.
• English at B2 level or higher and fluent Russian.
• Availability during UK working hours, and readiness to help with rare out‑of‑hours incidents.

Responsibilities

• Run and maintain our cloud infrastructure, mainly on AWS (EC2, VPC, IAM, S3, Route 53, CloudFront), with some GCP.
• Carry out planned maintenance: OS patching, updates and upgrades, backup checks and audit checks.
• Verify that MySQL backups actually restore and that failover works — safely, without putting production at risk.
• Look after monitoring and logging in Grafana and ELK: tune alerts, cut noise and turn signals into action.
• Handle requests from developers, Operations and our managed service partner, including access and permissions.
• Automate repetitive work with Python and Bash, and manage configuration with Ansible and Terraform.
• Take part in incident response and follow-ups, and help prevent the same issue from happening twice.
• Grow into owning a defined part of our infrastructure end to end.
