Machine Learning Researcher

Jane Street is seeking a Machine Learning Researcher to develop deep learning models for its trading strategies and advance its machine learning research. The role works closely with researchers, engineers, and traders on model training, system design, trading strategies, and research that supports new markets and situations.

Responsibilities:

• On our Machine Learning team, you'll build the deep learning models that power our trading strategies, supported by our rapidly growing computing cluster with tens of thousands of high-end GPUs
• Researchers, engineers and traders sit a few feet away from each other and work together to train models, architect systems and run trading strategies
• Depending on the day, we might be diving deep into market data, tuning hyperparameters, debugging distributed training performance or studying how our model likes to trade in production
• We’ll rely on your in-depth knowledge of the machine learning landscape and understanding of a variety of approaches—drawn from LLMs, image models, RL agents, recommendation systems or classical ML methods—to shape the future of ML at Jane Street
• You’ll train models for the next generation of our deep learning-based trading strategies, and build the fundamental understanding we need to tackle new markets and situations
• You’ll also be hiring new colleagues, attending conferences and teaching techniques to teammates—all of which we consider to be real and impactful parts of the job
