About Cboe

• Owning and evolving the team's machine learning training and deployment infrastructure on Snowflake, and building production-quality data pipelines.
• Passionate about leveraging cutting-edge Artificial Intelligence and Machine Learning to ensure the integrity and transparency of global financial markets

Responsibilities

• Deep learning: PyTorch, custom training loops, architecture design and experimentation, multi-GPU distributed ML, experiment tracking, model lifecycle management
• LLMs: building with LLM APIs in production, prompt, context, and harness engineering as an engineering discipline, agent orchestration, full stack development using coding agents

Requirements

• Data-reasoning instinct — able to say what the data is telling you and what data should go into a model in the first place, not just which model to reach for

Strong SQL and experience with large-scale datasets

• Production ML experience with time-series / sequential data — you've trained, deployed, and monitored models at scale, and you understand how time affects the structure of data: stationarity, regime change, leakage, and why a model that looks good in backtest fails live
• Deep learning applied to temporal or representation problems — sequence models, embeddings/similarity over time-series, or equivalent
• Excellent written and verbal communication
• Solid software-engineering foundation: 5+ years, primarily Python, with production practices (version control, automated testing, CI/CD, Docker) and comfort in an enterprise cloud data platform (Snowflake / Databricks / BigQuery, etc.) under real RBAC and governance constraints
• Bachelor's degree in a quantitative field
• Time series and sequential modeling: TCNs, transformers, time-contrastive learning, or similar approaches on temporal data, as well as classical time series modeling (e.g. ARIMA)

Preferred

• Classical ML: scikit-learn, weakly supervised clustering and anomaly detection, feature engineering, model evaluation for production decision systems

We work across deep learning, LLM agent systems, and classical ML. While you don't need to know all of these, you should have real depth in at least a couple of these, and curiosity about the rest:
