Senior Site Reliability Engineer – Remote UK

Role Overview

• Own SLOs, SLIs, and error budgets for all production services; drive error budget discipline across engineering
• Design reliability patterns for AI agent pipelines: LLM observability, tool-use tracking, failure detection, and graceful degradation
• Architect for blast radius containment — agent failures must have bounded customer impact through isolation, circuit breaking, and rapid recovery
• Mature our Canada Central/West active-active architecture toward 24-hour RTO with full regional failover
• Lead incident response and post-incident reviews that produce durable fixes; maintain DR procedures through regular testing
• Serve as the primary reliability liaison to Software and AI Engineering, translating requirements into actionable standards
• Partner with AI Engineering on compute provisioning, model serving, inference latency, and workload isolation
• Own CI/CD pipeline strategy (Bitbucket Pipelines, GitHub Actions) — set standards, optimize deployment frequency, and ensure teams can ship confidently
• Drive IDP adoption and enable teams on SRE practices: on-call readiness, SLO definition, runbook development, and self-service tooling
• Represent reliability in architectural discussions; surface risk before it's committed to design
• Own the service catalog — a living inventory of all services, AI agents, dependencies, ownership, and SLOs
• Operate Datadog as the single pane of glass for service health, infrastructure, and agentic pipeline telemetry
• Build golden path templates in Backstage and/or Atlassian Compass so teams ship reliably without routine SRE involvement
• Apply AIOps in Datadog to automate anomaly detection, incident triage, and remediation recommendations
• Own infrastructure as code via Terraform and GitOps; enforce IaC policy in partnership with Trust Assurance
• Own FinOps visibility into AWS cost segments; model cloud cost impact as AI/ML workloads scale
• Formally mentor junior and intermediate SRE engineers, with accountability for their technical growth and career progression
• Build AI-assisted automation to progressively reduce toil and scale the team's operational capacity

Requirements

• Bachelor's degree in Computer Science, Engineering, or equivalent combination of education and experience
• 6–8 years of progressive experience in site reliability engineering, platform engineering, or DevOps, with demonstrated technical leadership at the senior individual contributor level
• Deep expertise in AWS (EKS, Lambda, CloudWatch, AWS Config) and multi-region architecture patterns
• Proficiency with Terraform and GitOps; experience with policy-as-code (Sentinel, OPA/Rego, or equivalent)
• Hands-on Datadog experience at operational depth: dashboards, SLO tracking, alerting, log management, distributed tracing
• Strong containerization expertise: Docker, Kubernetes (EKS preferred)
• Proficiency in Python and/or Bash; experience building operational tooling; solid understanding of Java and Spring Boot microservice architecture sufficient to make reliability and deployment decisions for EKS-hosted services
• Deep expertise in CI/CD pipeline design and optimization using Bitbucket Pipelines and GitHub Actions
• Familiarity with IDP tooling (Backstage, Atlassian Compass, or equivalent) strongly preferred
• Experience with AI/ML workload infrastructure, LLM API integration, or agentic system operations considered a strong asset
