Era4 develops, owns and operates AI infrastructure across the UK, powered by renewable energy. Converting legacy industrial and energy sites into modern data-centre facilities, Era4 is combining brownfield regeneration opportunities with cleaner, efficient, scalable compute capacity for healthcare, research, finance, enterprise, and public-sector organisations
Role Summary:
We’re hiring SRE/Platform engineers with an automation bias to help build Era4’s operations capability from the ground up. You’ll turn runbooks, alerts and operational workflows into safe, auditable automation and internal tooling that improves reliability across our AI infrastructure and datacentre platform.
This is a Platform / SRE role with software engineering, not an AI model-building role. You’ll work closely with operations, platform and engineering teams to reduce manual toil, improve alert quality, and speed up incident response.
Key Responsibilities:
- Build Python-based automation for incident triage, runbook execution, and routine operational tasks.
- Integrate observability, ITSM and infrastructure APIs to enrich alerts and automate workflows.
- Improve monitoring signal quality through correlation, enrichment, suppression and deduplication.
- Build internal tools and self-service capabilities such as CLI utilities, ChatOps integrations and dashboards.
- Maintain version-controlled runbook-as-code and automation libraries.
- Translate post-incident learnings into better tooling, automation and operational standards.
- Support safe, auditable automation for higher-risk actions with appropriate approval controls.
Essential Experience:
- Experience in SRE, Platform Engineering, or production infrastructure operations.
- Hands-on experience with observability/monitoring tooling (for example Prometheus, Grafana or similar).
- Experience with Kubernetes, Terraform or comparable cloud-native / IaC tooling.
- Exposure to incident management / on-call and converting manual runbooks into automation.
- Experience with APIs, webhooks, event-driven systems and operational integrations.
- Experience with Python for automation, APIs and integrations.
Nice To Have:
- GPU, datacentre or colocation infrastructure experience.
- ITSM integrations (ServiceNow, Halo, Jira Service Management or similar).
- ChatOps tooling (Slack or Microsoft Teams bots).
- OpenTelemetry, logging or distributed tracing experience.
- DCIM, IPAM or hypervisor-control-plane integrations.
- Experience with LLM-assisted or agent-based operational automation.
Why Join Era4:
You’ll be joining a mission-driven start-up building critical national infrastructure, where operational excellence directly enables growth. This role offers high visibility with leadership, real autonomy, and the chance to shape how a next-generation company operates at scale.
Diversity & Inclusion:
Era4 is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
Skills Required
- Strong Python development skills for automation, API integration, and data processing
- Hands-on experience with observability and monitoring platforms (Prometheus, Grafana, Mimir or equivalent)
- Experience integrating with ITSM platforms (ServiceNow, Halo, Jira Service Management or similar) via API
- Understanding of event-driven architectures, message queues, and webhook-based automation patterns
- Strong understanding of managing GPU infrastructure in production and automating GPU workflows
- Familiarity with Infrastructure-as-Code principles and cloud-native environments (Kubernetes, Terraform or similar)
- Experience building LLM-powered agents using frameworks such as LangChain, LlamaIndex, Anthropic SDK, OpenAI function calling or comparable tooling
- Understanding of agentic design patterns, human-in-the-loop controls, and structured operational outputs
- Comfort operating in an API-first environment, integrating agents with DCIM, IPAM, and hypervisor control planes
- Prior experience in SRE, Senior Operations, or Platform Engineering with on-call and incident management exposure
- Experience converting narrative runbooks into executable automation or codified decision trees
- Understanding of ITIL-aligned incident and change management principles and ITSM tooling
- Exposure to data centre or colocation operations, particularly high-density compute or GPU environments
- Experience with ChatOps tooling and building Slack or Microsoft Teams bots
- Familiarity with DCIM platforms and telemetry pipelines (power, thermal, network)
- Knowledge of OpenTelemetry, distributed tracing, or log aggregation platforms (Loki, ELK, Splunk)
- Contributions to open-source observability or automation tooling
- Experience in a start-up or scale-up environment building tooling from scratch
