Role Profile
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.
What You’ll Be Doing
- 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.
This role provides an opportunity to develop your engineering skills while working on technology operating at significant global scale. You will gain hands-on experience with distributed systems, cloud-native engineering and real-time financial data while working alongside experienced engineers who can support your development. LSEG offers a range of tailored benefits and support, including healthcare, retirement planning, paid volunteering days and wellbeing initiatives.
Essential
- Hands-on software engineering experience, gained through employment, a graduate role, or open-source contribution.
