💡 “We’re not really deadline-focused” 💡

Understanding a hard problem properly takes time. At G-Research, our researchers have it.

Our research groups work much like academic PhD groups, where curiosity and collaboration drive the work. Researchers have the independence to choose which problems to pursue and the computing resources to test their ideas at scale.

If you’re an experienced ML or quantitative researcher who wants that kind of environment, we’d like to hear from you.

☁️ When cloud networks get faster, decompression can become the bottleneck. ☁️

In part four of our six-part open-source series, we explore how BtrBlocks uses lightweight encoding techniques to accelerate columnar decompression without sacrificing too much storage efficiency.

From adaptive encoding cascades to pseudodecimal compression, discover how BtrBlocks addresses the demands of high-bandwidth cloud infrastructure.

⛰️ The Bouldering Social 2026 ⛰️

Curious about a career in quantitative research? Come and climb with the people who do it.

We’re hosting an evening of bouldering in London with coaching from three climbing icons: Chris Sharma, Lynn Hill and Louis Parkinson.

Chris’s pioneering ascents have redefined the sport’s limits, Lynn was the first person to free climb The Nose on Yosemite’s El Capitan and Louis is a British professional climber and the founder of Catalyst Climbing.

You’ll climb alongside some of our researchers, then stay afterwards to talk with them about their work, the complex problems they tackle in quantitative finance and what research looks like at G-Research.

No climbing experience is needed and climbing shoes are provided.

🌟 Backing the next generation of researchers 🌟

Why would a quantitative firm fund PhD research with no conditions attached? Because many of machine learning’s biggest breakthroughs begin in university labs.

We're proud to support the researchers pushing the field forward. As our Academic Relations Manager Charles Martinez explains in a recent Bloomberg feature, the aim is to encourage great science.

Through NextGen, we have made the largest private-sector investment to date in ELLIS, supporting 36 researchers across Europe, and are fully funding 43 PhD students at eight UK universities.

💻 Meet the people behind Data Science at G-Research. 💻

Real-world financial data is large, noisy and rarely tidy. Our Data Scientists build the tools and datasets that make it usable for research.

Our Data Science internship offers the opportunity to explore this work first-hand. Over 10 weeks in London, you’ll apply your statistics and Python skills to real data alongside experienced researchers and engineers.

Hear from three of our Senior Data Scientists about the work they do, the problems they enjoy and what they look for in an intern.

✨ Good company, new experiences and time away from the everyday. ✨

At G-Research, we know that building strong relationships goes beyond working together.

That's why we offer Experience Days to everyone across the business, giving colleagues the chance to try something new and connect with people they might not work with day to day.

From exploring Paris by sidecar to cooking classes, countryside escapes and classic car experiences, there's been plenty to enjoy this year.

It's all part of creating a workplace where people feel valued, supported and connected.

💾 Modern AI workloads are changing the demands we place on data storage. 💾

In part three of our six-part series, we examine how Lance addresses these challenges through its approach to structural encoding, I/O scheduling and dataset versioning.

From minimising disk reads to supporting efficient access to complex, nested data, discover where Lance fits alongside Parquet and Apache Arrow.
