TL;DR · Senior ML/AI Modeler, Risk Automation Machine Learning

The Careers - Senior ML/AI Modeler, Risk Automation Machine Learning joins the Risk Automation ML team to automate risk and compliance investigations. This senior role involves owning strategic roadmaps and building agentic and generative AI systems to improve analyst productivity or eliminate manual decision loops. You will develop transformer-based ML models using diverse datasets, including payment transactions, asset graphs, and unstructured text. Key responsibilities include managing API calls to disparate data sources, performing advanced prompt tuning, orchestration, and production monitoring. The technical stack includes Python, LLMs, Pytorch, Snowflake, Airflow, and cloud services across GCP and AWS. You will also utilize agentic tools like Claude Code, Codex, and Openclaw. This work addresses the business problem of identifying fraudulent, illegal, and brand-violating activity across traditional and blockchain networks.

What you'll do

  • Experiment and deploy AI copilot and autopilot systems to improve analyst productivity and eliminate manual decision loops.
  • Own the end-to-end system including API calls, prompt tuning, orchestration, metrics, evaluation, productionization, and monitoring.
  • Build transformer-based ML models using diverse data sets like payment transactions, asset graphs, and unstructured text.
  • Work cross-functionally with product, platform, engineering, and operational stakeholders to deploy and tune production-grade systems.
  • Utilize Python ML stack, LLMs, Pytorch, Snowflake, Airflow, and cloud services (GCP and AWS) to execute tasks.
  • Use agentic tools like Claude Code, Codex, and Openclaw to accelerate research, development, devOps, and documentation.
  • Drive strategic roadmaps and priorities to completion by collaborating with relevant cross-functional stakeholders.

What we're looking for

  • 8+ years of Machine Learning modeling experience.
  • A Master's or advanced degree in computer science, data science, operations research, applied math, stats, physics, or a related technical field.
  • 3+ years of experience with AI engineering, Large language models, and traditional NLP techniques (preferred).
  • Full stack ML experience (preferred).
  • Experience building and deploying ML/AI to production systems that are performant at scale.
  • Experience independently owning and driving programs with multiple cross-functional stakeholders.
  • Proficiency with Python ML stack, LLMs, Pytorch, Snowflake, Airflow, and cloud services (GCP & AWS).
  • Ability to work from any location in the United States or Canada.
