Senior DevOps Engineer

We are a real time communications company that runs on our own infrastructure. We are looking for a senior engineer to add depth to the team that runs it.

Key Responsibilities

• Operate and improve our Proxmox VE virtualisation estate across data centre sites.
• Own storage performance and integrity: architecture, replication, backups, and recovery procedures that are actually tested.
• Build and maintain infrastructure as code with Ansible and Terraform – the estate should be reproducible, not folklore.
• Run container orchestration day to day and help lead our path deeper into Kubernetes.
• Keep monitoring and alerting sharp, so problems are found by us and not by customers.
• Write things down: runbooks, diagrams and clear proposals for the changes worth making.
• Get hands on in the data centre when the work calls for it.

Qualifications

• Five or more years in DevOps or infrastructure roles at modern companies – SaaS, telecoms or infrastructure-heavy environments ideally.
• Production Kubernetes experience – designing, running and debugging real workloads. This is the biggest win.
• Proxmox experience, especially Ceph and block storage – a close second.
• Strong infrastructure-as-code habits with Ansible, Terraform or similar.
• Linux administration at scale, bare metal and virtual.
• Comfortable in production-critical environments where uptime is non-negotiable – business communications can’t go down.
• UK-based, within reach of Southampton for office days and data centre visits.

What We Offer

• Competitive salary and benefits package.
• Real infrastructure at real scale – your own hardware, not just someone else’s cloud.
• Hybrid working from our Southampton office.
• Professional development and career growth opportunities.
• Collaborative and innovative work environment.
