Work on applying AI/ML (including LLMs, deep learning, and reinforcement learning) to support portfolio managers, researchers, traders, and risk managers in a quantitative finance setting. Responsibilities include experimenting, iterating, and productionizing models and building supporting data and ML infrastructure such as feature stores, deployment frameworks, and measurement/retraining pipelines. Collaborate closely with business stakeholders, quants, and researchers to understand problem spaces and deliver measurable AI solutions. Strong software engineering, Python expertise, and experience with cloud platforms and LLM techniques are required.
We are working on different areas where AI/ML can help portfolio managers, researchers, risk managers, and other functions. Some examples are: enabling traders/researchers to consume vast amounts of research and literature by organizing, summarizing information, sometimes in near real-time; doing quantitative modeling to price instruments, modeling demand and supply of commodities and other fundamentals; modeling weather, optimizing algorithmic execution of trades; modeling and building simulations of risk.
The AI/ML work spans usage of LLMs, deep learning, reinforcement learning and other ML techniques. The work also requires building AI/ML infrastructure for data wrangling, building feature stores, building frameworks for deployments, measurements, re-training, etc.
We are seeking a AI/ML SWE who has experience with LLMs, deep learning, reinforcement learning as well as an interest and ability to keep up with advancements in AI/ML. The candidate should also be strong in software engineering and be comfortable with AI/ML experimentation and productionization.
