## Description

Exciting opportunity to work at a tech-centric prop trading fund which trades a wide range of financial products, with offices across the globe. Looking for an experienced engineer with low-level systems programming and optimization expertise to join their growing ML team.

Machine learning is front and centre at this firm, and your focus will be to optimize the performance of their models: both training and inference. They're interested in efficient large-scale training, low-latency inference in real-time systems, and high-throughput inference in research. Partly this will involve improving straightforward CUDA, but they also need a whole-systems approach, including storage systems, networking, and host- and GPU-level considerations.

The successful candidate will be a smart, curious software engineer who enjoys finding solutions for complex problems. If you also have a great appetite for learning new things, this role is for you!
