Site Reliability Engineer

About the Role

We are hiring a Site Reliability Engineer to help us run and improve LSEG's internal observability platform. The focus of this role is the platform itself - its reliability, supportability, and usability - and the standards and self-service patterns that help teams adopt it consistently.

What You Will Be Doing

• Platform Operations and Reliability
• Monitor platform health, investigate and diagnose issues, and support service recovery across production and non-production environments.
• Contribute to service readiness through dashboards, SLOs, SLIs, runbooks, resilience checks, and performance validation.
• Use metrics, logs, traces, and service health data to understand issues and guide practical decisions.
• Incident Response and Continuous Improvement
• Support incident response, triage, problem management, and root cause analysis.
• Drive follow-up actions that reduce repeat issues and improve operational consistency.
• Improve automation and GitOps-based workflows to reduce manual work across the team.
• Enablement and Documentation
• Maintain documentation, onboarding guides, and self-service tooling so teams can operate with less reliance on direct support.
• Provide direct enablement on telemetry standards, alerting guidance, SLO practices, and platform workflows.

Requirements & Tech Stack

• Experience supporting production platforms or services in an SRE, platform engineering, infrastructure, DevOps, or operations engineering role.
• Experience using observability data such as metrics, logs, traces, alerts, dashboards, or service health views to investigate issues.
• Understanding of incident response, problem management, service readiness, or operational support processes.
• Experience using automation or infrastructure-as-code practices to support repeatable delivery and operations.
• Solid understanding of cloud, container, Linux, networking, or distributed system environments.
• Ability to communicate technical information clearly to engineering, operations, and service stakeholders.
• Experience writing or maintaining operational documentation such as runbooks, support guides, or onboarding material.
• A practical approach to improving reliability, reducing manual work, and helping teams use shared platforms optimally.

Desirable Skills and Experience

• Experience with observability, monitoring, telemetry, or data pipeline technologies such as OpenTelemetry, Grafana, ClickHouse, Cribl, Datadog, BigPanda, Redis, Flink, or similar tools.
• Experience with GitOps workflows and tools such as Git, CI/CD pipelines, pull requests, environment promotion, or configuration-as-code.
• Experience building or supporting internal platforms used by multiple engineering teams.
• Experience defining or using SLOs, SLIs, error budgets, alert quality measures, or service health models.
• Experience supporting telemetry pipelines, data routing, data filtering, retention, or cost management.
• Experience working in a regulated, financial services, or large enterprise technology environment.
• Experience helping engineering teams adopt shared standards, templates, or self-service platform capabilities.
