ROLE SUMMARY:

FTSE Russell (LSEG) is building next-generation distribution capabilities that deliver index data to the global financial community — across APIs, cloud platforms, and modern data delivery channels. We’re looking for a hands-on Senior Engineer to design and scale the systems that power this distribution — enabling reliable, secure, and high-performance data delivery to institutional clients worldwide. This is an individual contributor role with strong technical leadership expectations, where you’ll own system design, data modelling, and engineering standards across a critical client-facing platform.

WHAT YOU'LL BE DOING:

Design and build scalable data distribution systems, delivering data via APIs, cloud platforms, and client-facing services. Own system architecture and data modelling, ensuring performance, reliability, and maintainability at scale. Develop secure, well-designed APIs and data services for external consumers. Drive engineering quality through testing, review, and standards, ensuring production-grade delivery. Partner closely with product and stakeholders to translate complex requirements into robust technical solutions.
