Site Reliability Engineer

Site Reliability / Platform Engineer

We are recruiting for a growing technology infrastructure business that is building a new operational capability to support large-scale high-performance computing environments.
This is an excellent opportunity for an experienced Site Reliability Engineer or Platform Engineer who enjoys automating things rather than repeatedly fixing them manually.
The role sits at the intersection of infrastructure operations and software engineering. You will use Python and modern automation techniques to improve reliability reduce manual workload and make incident response faster and more effective.
What youll be doing

Youll build Python-based automation around incident management operational runbooks and routine infrastructure tasks.
Youll integrate monitoring infrastructure and ITSM platforms through APIs helping improve the quality of alerts through better correlation enrichment suppression and deduplication.
Youll also develop internal tools command-line utilities dashboards and potentially ChatOps capabilities that allow operational teams to resolve issues more quickly.
A major part of the role will be taking existing operational processes and asking:
Why are we still doing this manually
Youll then design a safe controlled and auditable way of automating it.
What were looking for

You should have good commercial experience in Site Reliability Engineering Platform Engineering DevOps or production infrastructure operations together with strong hands-on Python automation skills.
Youll also need experience with:

• Monitoring and observability tools such as Prometheus Grafana or similar
• Production incident management and/or on-call environments
• Automating operational runbooks and repetitive infrastructure processes
• APIs and systems integration
• Version-controlled automation and operational tooling

Experience with any of the following would be particularly useful:
ServiceNow Halo Jira Service Management OpenTelemetry distributed tracing Slack/Teams automation datacentre or colocation environments GPU infrastructure DCIM IPAM virtualisation platforms or LLM-assisted operational automation.
This is not an AI/ML development position. Were looking for someone who understands production infrastructure and can use software engineering and automation to make that infrastructure more reliable.
Youll be joining a growing organisation where youll have considerable autonomy and the opportunity to help shape the SRE and operational automation capability rather than simply inherit an established environment.
