Site Reliability Engineer

Location: London office, hybrid — 2 days per week onsite

About the Role

We're seeking a hands-on Site Reliability Engineer to enhance our production reliability, scalability, and operability. You'll use your expertise across observability, Kubernetes, AWS, and infrastructure as code to investigate issues, implement tactical fixes quickly, and drive strategic improvements that raise availability and reduce toil. This is a hybrid role with two days per week in the office. You'll collaborate closely with engineering, product, and support to design, build, and run robust platforms that meet demanding SLAs/SLOs.

What You'll Do

• Keep production healthy: Monitor, troubleshoot, and resolve incidents across services and infrastructure; reduce MTTR and prevent recurrences through high-quality post-incident actions.
• Observability as a first‑class practice: Use Grafana, Datadog, and Splunk (and related tools like Prometheus/OpenTelemetry) to detect anomalies, root cause issues, and create actionable alerts and dashboards.
• Run Kubernetes at scale: Operate and harden Kubernetes (EKS preferred); manage deployments, autoscaling, rollouts/rollbacks, service mesh/ingress, and cluster upgrades.
• Build reliable cloud foundations: Design and operate AWS workloads (networking, IAM, EC2/EKS, RDS/Aurora, S3, CloudWatch, ALB/NLB, VPC, Security Groups) with a security-first mindset.
• Automate with IaC: Codify and continuously improve infrastructure using Terraform (modules, workspaces, remote state, policy as code).
• Enable fast, safe delivery: Partner with teams to enhance CI/CD pipelines (e.g., GitHub Actions/Jenkins/Argo CD), progressive delivery, and change management to lower the change failure rate.
• Own reliability metrics: Define and iterate on SLOs/SLIs/error budgets; champion blameless post‑mortems and reliability reviews.
• Participate in on‑call: Join a fair, well‑documented on‑call rota; improve runbooks, automation, and alert quality to make on‑call sustainable.
• Drive strategic improvements: Identify systemic issues and deliver durable fixes (architecture, capacity, scaling, caching, resilience patterns, rate limiting, back‑pressure, circuit breakers, chaos engineering).

What you will bring

• 5+ years operating production systems as an SRE, DevOps engineer, or software engineer.
• Observability: Hands‑on with Grafana, Datadog, and Splunk for incident investigation, dashboarding, alerting, tracing/logs/metrics correlation, and performance analysis.
• Kubernetes: Strong experience running and troubleshooting workloads (controllers, pods, networking, storage, HPA/VPA, Helm/Customise).
• AWS: Solid practical knowledge of core services and best practices for security, cost, and reliability.
• Terraform: Confident with module design, state management, DRY patterns, and CI for IaC.
• On‑call experience: Demonstrated participation in a production on‑call rota, effective incident communication, and post‑incident follow‑through.
• Scripting & engineering fundamentals: Proficiency in at least one of Python, Go, or Bash; strong Linux, networking (DNS, TLS, HTTP, TCP), and Git.
• Collaboration & communication: Ability to work cross‑functionally, write clear runbooks/RFCs, and influence engineering practices.

Nice‑to‑Have

• EKS internals, cluster autoscaler, managed node groups/Fargate; service mesh (Istio/Linkerd), ingress controllers (Nginx/ALB).
• Prometheus, OpenTelemetry, Loki/Tempo, alert tuning and SLO burn‑rate alerts.
• Argo CD/FluxCD, Helm chart authoring, Kustomize.
• CD patterns (blue/green, canary, feature flags), GitOps workflows.
• Database operations (Postgres/MySQL), caching (Redis), message queues (Kafka/SQS).
• Security & compliance (CIS benchmarks, IAM boundaries, secrets management, Vault/Sealed Secrets).
• Resilience testing/chaos engineering.
• Relevant certs (AWS Solutions Architect/DevOps Engineer, CKA/CKAD, Terraform Associate).

How We Work

• Hybrid: Two days per week in the office for collaboration and incident/architecture reviews; remote the rest.
• Engineering excellence: Blameless culture, well-defined SLOs, automation‑first, and continuous learning.
• Impact focus: Measure success via availability, latency, MTTR, change failure rate, toil reduction, and customer outcomes.

On‑Call Expectations

• Participate in a rotating on-call schedule with clear escalation paths.
• Improve alert signal-to-noise ratio and operational readiness (dashboards, runbooks, playbooks).
• Post-incident reviews focused on learning and durable improvements—no blame.

Benefits

• Competitive salary + bonus (DOE)
• Pension and comprehensive benefits
• Modern tooling and time allocated for reliability improvements

We encourage applications from people of all backgrounds to enable us to bring diverse perspectives to our thinking and conversation. It's important to us that we strive to have a workforce that is diverse in the widest sense.
