Job summary

Source Group International is hiring a Site Reliability Engineer in London on a hybrid basis. The role focuses on defining SLOs/SLIs, improving observability, and leading cost-optimisation across cloud and on-prem environments.

You will collaborate with engineering teams to strengthen resilience, automate toil, and manage incidents while balancing performance and cost.

Qualifications

• 3+ years experience in SRE, Platform, or DevOps roles within production environments.
• Strong Kubernetes operational experience (on-prem and AWS EKS).
• Hands-on experience defining and operating SLOs/SLIs, alerting, and incident workflows.
• Deep understanding of observability and telemetry (monitoring, logging, tracing).
• Infrastructure as Code with Terraform; experience with GitOps workflows and CI/CD.
• Scripting proficiency in Python, Bash, or Go.
• Proven ability to balance cost efficiency with reliability and performance.
• Excellent communication across multiple teams.

Responsibilities

• Partner with engineering teams to define, measure, and manage SLOs/SLIs using error budgets.
• Enhance observability across services (metrics, logs, traces) to detect issues.
• Lead cost optimisation: monitor spend, right-size workloads, tune autoscaling.
• Improve production readiness via pre-deployment checks and post-release validation.
• Introduce and run chaos engineering experiments to strengthen resilience.
• Automate operational processes to reduce toil across the stack.
• Support major incident response and root-cause analysis.
• Collaborate across teams to raise standards for stability, security, performance, and compliance.
