We just wrapped up our global Kids Day celebrations, and every year, they somehow get even better. It was such a joy to welcome mini HRTers into our offices for a day of creativity, curiosity, and a little bit of chaos.

One crowd favorite was the froyo truck in NYC. And no—we didn't bring it in for Kids Day! It's always here… for the adults. 😉

Thanks to everyone who helped make this year’s celebrations so much fun around the world. 🎉

To reach the servers at Lefdal Mine Data Centers, you have to tunnel into a Norwegian mountain.

Inside lies one of the most unusual HPC environments in the world, where cold seawater from a nearby fjord cools dense GPU clusters designed for large-scale AI workloads — powered entirely by renewable energy.

Environments like Lefdal make it possible for HRT to scale the infrastructure behind our research. Our deployment includes direct-liquid-cooled racks of NVIDIA Blackwell GPUs operating above 125 kW per cabinet, integrated with high-speed interconnects and bespoke storage systems built to keep our research pipelines saturated.

In this video, we take a look inside the mine at the compute and networking infrastructure powering HRT’s cutting-edge research: https://youtu.be/kWPl7Awtq5U

2028 grads, join us for Inside HRT!

This immersive three-day program invites undergraduate STEM students to our NYC headquarters for engaging tech talks, interactive panels, and hands-on workshops.

Inside HRT is designed for students who are curious about quantitative finance but have little or no prior exposure to the industry. The program aims to provide essential learning that removes barriers and creates opportunities for promising STEM students. No finance experience necessary!

Program Details:
📅 May 18 - 20, 2026
📍 New York City
📝 Apply by March 26, 2026

We just open-sourced ‘slang-server’, a SystemVerilog language server that we built for intelligent code navigation and linting across hardware codebases.

Our latest blog post breaks down how we work with open source at HRT, and more broadly invest in developer efficiency. It also includes technical breakdowns of how we used the Slang library to build the language server, and how a series of targeted optimizations led to sub-second indexing across thousands of files.

Check it out on the HRT Beat:

At HRT, pushing technical boundaries often means moving beyond the constraints of standard software. Some of the ways we accomplish this are by deploying FPGA and ASIC solutions which allow us to reach latency and throughput levels unattainable with general-purpose CPUs. We build the custom logic ne...

Explore HRT is going global! 🎉

We’re inviting standout 2028 grads in math, CS, and other STEM-related fields to spend three days getting a closer look at how we work and learn together at HRT. You’ll hear directly from our engineers and researchers, work alongside our teams, and see how quantitative trading actually works under the hood. Travel and lodging are provided.

📍 London · April 7–9
📍 NYC · April 29–May 1
📍 Singapore · May 13–15
Singapore applications open February 23.

Please select only one location when applying, and choose the office where you’d be interested in future internship or full-time opportunities.

With 2025 in the books, we’re taking a moment to look back at the exceptional lineup of speakers our Learning & Development team brought in to share their expertise across engineering, finance, and beyond. Over the past year, learning how these experts approach hard problems has helped HRTers stay sharp, challenge assumptions, and remain curious.

💻 Wes McKinney, creator of pandas, traced the rise of the composable data stack and how modern columnar formats power high-performance analytics and AI.

📈 Donald MacKenzie, author of Trading at the Speed of Light, spoke in London about how electronic markets have evolved over the last 30 years.

🚀 Bill Ochs, former James Webb Space Telescope project manager, broke down how one of the most complex scientific systems ever built came together under extreme technical constraints.

🪸 Dr. Helen Fox of the Coral Reef Alliance demonstrated how data science is improving coral reef resilience across the world’s oceans.

🏎️ Neil Martin, a pioneer of data analytics in Formula 1, shared how elite F1 teams turn uncertain data into racing strategies.

💵 Bruno Dupire, head of Quantitative Research at Bloomberg, explored multi-leg bundle trading, showing how matching portfolios rather than individual securities can reduce ex*****on risk and improve pricing.

👾 Dan Fu, UCSD professor and VP of Kernels at Together AI, explained how custom GPU kernels drive performance gains.

We appreciate their insights and look forward to even more opportunities to learn in 2026!

What a team, what a year! We wrapped it up the best way we know how: together.

Happy holidays from all of us at HRT. Whether at conferences, on campus, in the office, or just online— we’ll see you in the new year. 👋
