Powered through partnerships and technology

LSEG’s strategic partnership with Microsoft is reshaping how financial services are built, delivered, and experienced. Guided by our ‘LSEG everywhere’ AI strategy we are creating next-generation AI-ready data, analytics, and cloud infrastructure solutions – empowering our customers to make more possible.

Together, we are redefining how customers will choose, access and use our products. By accelerating innovation and simplifying complexity, we are transforming how financial institutions operate, engage with their customers, and collaborate with each other.

Engineers are central to this journey – co-developing secure, cloud-native solutions that simplify workflows and unlock new value. Working with advanced Azure technologies like Synapse, Fabric, Purview and Copilot, our teams are delivering intelligent tools and scalable infrastructure that reshape how the industry accesses and acts on information.

Together we’re pioneering innovative solutions that enable our engineers to learn, grow and lead in a global, cross-functional environment.

In collaboration with Amazon Web Services (AWS) we are transforming how financial markets operate. AWS is our preferred cloud provider for key divisions including Markets, Risk Intelligence, and FTSE Russell, supporting our mission to deliver scalable, secure, and resilient infrastructure for customers worldwide. 

Operational resilience is the foundation of everything we do – and cloud services are the cornerstone of our approach. As Daniel Maguire, Group Head of Markets at LSEG, explains:

“We look forward to working with AWS to deliver innovative products and an enhanced experience for our customers.” 

Building on AWS opens up opportunities for engineers to work on some of the most advanced cloud and AI technologies in the industry. From leveraging Amazon Bedrock to accelerate risk analysis and building AI-powered market surveillance tools, to migrating 30 petabytes of Tick History data to AWS for cost optimisation, engineers at LSEG are shaping solutions that redefine speed, resilience, and compliance. You’ll also be part of chaos engineering experiments using AWS Fault Injection Service to strengthen operational robustness, and benefit from AWS’s Experience-Based Acceleration programme, which upskills teams to lead critical migrations. With innovations like AWS Outposts for hybrid integration and AWS Data Exchange for market insights, you’ll collaborate directly with AWS experts to deliver products that set new benchmarks for financial technology. 

At LSEG, our tech stack reflects the scale, complexity and ambition of our mission: to power global financial markets with speed, resilience and innovation. Our cloud network processes over 500 million packets an hour and our engineers work across a rich ecosystem of tools, platforms and languages.

Whether focused on backend systems, data architecture or customer-facing platforms, our teams bring curiosity and expertise to every challenge.

We use a wide range of technologies-including programming languages such as Java, Python, C++, Go and .Net. Frameworks like Angular and React. This diverse stack enables us to process 40 billion market updates every day, deliver scalable microservices, and build real-time data pipelines and containerised infrastructure. DevOps principles and CI/CD pipelines help us deliver fast, reliable deployments.
