Senior Software Engineer (Real-Time)

• As a Software Engineer in LSEG’s Real-Time Engineering organisation, you will work on a global low-latency market data platform that sends billions of price updates per-day around the globe
• In this role, you will build APIs, telemetry pipelines and synthetic monitoring services that show how reliably and quickly market data reaches customers
• You will work with experienced engineers to develop production software, measure performance and enable observability of a globally distributed platform
• Prior market-data or observability experience is not required; we are looking for strong engineering fundamentals, curiosity and a willingness to learn
• You will work with experienced engineers to build the software and data stack that measures how our Real-Time application delivers data from hundreds of global exchanges to thousands of customers
• You will help turn software signals and synthetic monitoring data into useful end-to-end insight across LSEG’s Real-Time platform
• You will contribute to software that brings together telemetry from individual applications and services, helping engineering and operations teams understand service health, performance and customer impact
• This is a hands-on development role for an engineer at an early stage of their career who wants to build experience in mission-critical distributed systems, observability, cloud-native engineering and real-time financial technology
• Build and improve software components that aggregate, correlate and present data from over 30 global distribution sites
• Develop applications and data-processing logic that help identify performance issues, service degradation and hotspots across distributed systems
• Contribute to telemetry pipelines that ingest, transform and route metrics, logs and traces into a common observability layer
• Deliver synthetic monitoring capabilities that measure the performance and experience of Real-Time services from locations around the world
• Develop APIs, automation and configuration used to manage observability services and capabilities
• Use Git, CI/CD and configuration-as-code practices to deploy and maintain software and observability assets consistently across environments
• Work with engineering squads to add and improve instrumentation within applications across Development, Test, PPE and Production environments
• Work alongside expert engineers to learn modern approaches to observability, distributed systems, cloud-native software and real-time data platforms
• Contribute ideas and improvements as the Real-Time observability platform continues to evolve
