Are you an expert Data Science leader with experience shipping real AI products to customers? Do you want to build innovative solutions for financial professionals with teams of brilliant, collaborative data scientists, software engineers, UX researchers, and product managers? If so, we’d love to talk to you!
About Us
The London Stock Exchange Group (LSEG) is a global leader in financial market infrastructure, with a large and diverse portfolio of data, products, and services. LSEG's Data & Analytics division has a long history of using classical machine learning (ML) techniques, and we're also at the forefront of using GenerativeAI to build intuitive solutions that use the wealth of information in our documentation, datasets, and APIs.
The Role
We’re looking for an exceptional leader to help build and scale an organization to deliver on this promise. You'll solve customer problems using a combination of classical ML and GenAI technologies, delivering products that both delight our external customers, and help internal customers do their jobs effortlessly. We are not a PoC shop - we ship real products - so we're looking for someone who delights in the messiness of shipping AI-first products.
Key Responsibilities
- Define, drive agreement on, and execute on a strategic data science vision
- Hire and develop diverse and impactful data science leaders and teams, providing technical oversight and standardized training
- Provide technical mentorship and support while letting your team make key decisions and learn from their mistakes
- Work with Product Managers and Software Engineering leaders to define and iteratively deliver roadmaps
- Build a collaborative team environment
Qualifications
- Master's degree in Computer Science, Statistics, Mathematics, or related field, or equivalent work experience
- At least 5 years shipping machine learning models, ideally over the full product development lifecycle
- At least 2 years leading data science/machine learning teams indirectly (i.e., managing managers)
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
