Infrastructure Support Engineer - Contract

ABOUT OLIX
AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. The OLIX Decode Accelerator 1 (DX-1) is the first accelerator architected specifically for decode. Rack-scale co-design of logic, data movement, packaging, optics and interconnect enables a step change in system level performance.
THE ROLE
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.
Start date: ASAP
Location: London, with working overlap for Austin and India
Contract: 6 months
RESPONSIBILITIES
- 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.
SKILLS & EXPERIENCE
Required:
- Five or more years of Linux administration on Ubuntu or RHEL: users and permissions, filesystems, storage, networking, SSH, remote desktop.
- AWS: EC2, S3, IAM, VPC, Secrets Manager.
- Terraform and Ansible — reading and changing existing code, working through pull requests.
- GitHub administration: organisations, repositories, permissions, Actions runners.
- Experience working in a ticket queue against response and resolution targets.
- Clear written runbooks and documentation.
Useful:
- Cloudflare Zero Trust and WARP.
- FlexLM licence administration.
- SLURM and HPC or EDA compute environments.
- Semiconductor or engineering environments using Cadence or Synopsys tools.
- Kubernetes.
Due to U.S. export control regulations, candidates' eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.
