## Description

We're hiring one Infrastructure Support Engineer on a six-month contract to run day-to-day support for OLIX's production infrastructure: AWS, GitHub, Cloudflare, Terraform, Ansible, Linux and Kubernetes.

You'll be the first line for every infrastructure request across engineering - unblocking people fast, then removing the cause so the request stops coming back. The measure of success is simple: requests resolved in hours rather than days, and a queue that shrinks as automation takes over the repetitive work., * Own the infrastructure support queue, responding to every request within 15 minutes and aiming for resolution in hours, not days.

 * Resolve procedural requests end to end: access, permissions, capacity, licence installs, host rebuilds, DNS records, runner and repository administration.
 * Apply changes through Terraform and Ansible in the infra repository, by pull request.
 * Build self-service tooling and automations for common request types, removing blockers to engineering work.
 * Write and maintain runbooks for incidents affecting core infrastructure.
 * Escalate to infrastructure engineering where appropriate.
 * Monitor capacity and licence expiry, and resolve proactively before limits are hit.
 * Report weekly on volume, resolution times, top causes, and work removed by automation.

What this role does not cover: designing or building new platforms, owning the EDA platform build programme, end-user IT support (laptops, phones, Microsoft 365, identity provisioning - these stay with the IT support team), or security incident response.
