Sr Engineer-Machine Learning

Are you passionate about leveraging cutting-edge Artificial Intelligence and Machine Learning to ensure the integrity and transparency of global financial markets? As a Senior Machine Learning Engineer - Regulatory at Cboe Global Markets, you’ll have the opportunity to work with a highly skilled team to prototype, train, and deploy ML models and AI applications that monitor financial markets generating terabytes of new data every trading day. You’ll be at the forefront of innovation, utilizing advanced AI tools and scalable data engineering to transform complex data into actionable insights. If you thrive on tackling real-world challenges, excel in programming and large-scale data operations, and want to make a meaningful impact in a fast-paced, highly regulated environment, this is your chance to join a team where your expertise will help shape the future of market oversight. Step into a role where your ideas drive progress, and your contributions truly matter-apply now and help us turn data into value.

Your responsibilities will be:

Collaborate with the team on machine learning experiments across order book analysis, alert detection, and sequential financial data

Develop and operate AI agent systems in production, applying ML engineering discipline to nondeterministic LLM-based software development workflows

Own and evolve the team’s ML training and deployment infrastructure on Snowflake

Build production-quality data pipelines for processing terabytes of daily financial market data

Raise the engineering bar through rigorous code review, architecture guidance, and mentorship of junior and mid-level engineers

Design and develop production-quality, test-driven Python code

Develop explainability and process-compliance solutions for AI and ML

Effectively track and evaluate ML model performance across training, validation, inference, and monitoring

Work in both on-premises and cloud environments

Work closely with complementary engineering teams

Produce clear and thorough documentation, including ML proposals, experiment specifications, technical design, and testing scenarios

Bachelor’s degree in a quantitative field

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.

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.

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

Excellent written and verbal communication

Machine Learning Skills

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:

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

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)

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