What we do
Our engineers power a global financial ecosystem that extends far beyond the London Stock Exchange. We design and deliver the infrastructure behind some of the world’s largest and most relied-upon data platforms, trading systems, risk intelligence tools and sustainable investment solutions. This includes data and index capabilities that cover 99% of global market capitalisation, giving customers clarity across nearly all global markets.
We’re a product-led organisation with global teams working at scale to build technology that puts customer needs first. By breaking down silos and empowering our engineers to own the full product lifecycle, we foster collaboration, innovation and accountability. Together, we create resilient platforms and data solutions that help clients seize opportunities, manage risk and build a more sustainable future.
And as a regulated business, we build trusted, resilient technology that meets the highest standards, unlocking possibilities for our customers and playing a vital social and economic role in the world's financial system – from platforms that help protect pensions and long-term investments, to systems that detect financial crime in real time and keep global markets safe, fair and transparent.

The principles behind everything we build
Our Engineering Principles empower engineers to lead change, solve critical challenges, and deliver solutions that matter, at a scale few can match. They are underpinned by our values – Integrity, Partnership, Excellence, and Change.
Engineers operate with purpose. We start with WHY. We clearly define the problem to be solved, opportunity to be seized or hypothesis to test. We partner to deliver our strategic objectives and drive measurable commercial outcomes to serve our customers.
Engineers put customers first. We work backwards from customers’ needs, design products that address real-world problems and continuously seek feedback to drive excellence. We work
hard to build trust by delivering products that surpass customer expectations, every time.
Engineers tackle complex problems. We go beyond our comfort zones and push boundaries to deliver excellence. There is no place for mediocrity in engineering. We bring the outside in, set ourselves stretching ambitions and learn from the best so we can innovate and inspire others too.
Engineers have a growth mindset, with a natural curiosity driving us to learn at every opportunity. We continuously acquire expertise, learning in both formal and informal settings, and actively share our knowledge within the community. We demonstrate an eagerness to explore new possibilities and actively pursue them.
Engineers have high standards for talent. We take accountability for our own development, invest in our teams, recognize achievements and stretch ourselves to grow. Engineers are always building future leaders, coaching and investing in the next generation of talent.
Engineers are owners. We are proud to work at LSEG and we operate as though this is our business. We treat the company’s capital and resources as we would treat our own, prioritising sustainable value over short term gains. We are empowered to make decisions that are right for LSEG, operate beyond silos, and challenge status-quo
Engineers seek the truth and value precision. We inform opinions with measurable data. We use the insight it provides to be vocal when calling out risks and, when things don’t go to plan, we use it to learn from our mistakes.
Engineers are not afraid (and never too senior) to roll up their sleeves. We dive deep into the subject matter and stay connected to the details. When metrics and expected outcomes differ, we seek to understand the reasons, adjust swiftly, and take appropriate action.
Engineers deliver with ambition and build responsibly. Scalability, reliability and security are the foundation of everything we build. We always have a clear end goal, with incremental releases to reach it. We actively seek out feedback from customers, test hypotheses and assumptions and time box them to assess, learn and adjust quickly.
Engineers don’t just build products, we have a responsibility to build an inclusive, respectful environment too. We drive high performance by communicating, collaborating, challenging constructively, and listening actively. We recognise that HOW we work together is just as important as WHAT we achieve.
