Senior Associate Engineer, Site Reliability Engineering

About the role

We’re looking for a Site Reliability Engineer to join LSEG’s Real Time SRE team. The role supports a large, globally-distributed market data infrastructure, providing support for critical real‑time applications, automating development and operational toil, and driving adoption of modern tools and platforms. Candidates should be strong individual contributors with operational support and development skills, experience with complex distributed systems, and strong communication abilities. Responsibilities include collaborating across infrastructure, networks, data quality, and development teams to ensure service health; ensuring end‑to‑end quality for application migrations to cloud; supporting applications on on‑premise data centers and public/private cloud (AWS/Azure); automating toil via scripting and Git; leveraging tools to accelerate incident response; crafting dashboards and alerting pipelines; integrating cloud services and tooling; designing and maintaining CI/CD pipelines; and defining service level objectives and monitoring. Requirements include at least five years of DevOps or SRE experience, hands‑on cloud support (AWS/Azure), production‑grade Python coding, Unix/Linux expertise, container technologies (Docker, Kubernetes, Azure AKS, AWS EKS), CI/CD pipeline design, observability components (alerts, dashboards, log‑parsing, automated remediation), and documentation skills. The role offers experience coordinating large‑scale technical initiatives, low‑latency market data support, cutting‑edge platforms, and a dynamic team. LSEG values flexibility and may discuss work arrangements.
