Additionally, we use generative AI technologies to improve agent workflow and case review tools, by adding features that accelerate agent productivity and allow them to make more informed and accurate decisions.

  • Build classification models to detect illegal use of the app across the peer-to-peer, banking, card, equities, and bitcoin products
  • Leverage diverse data sets, including payment transactions, connected users, and asset graphs, unstructured text data, and user profile information to build ML and generative AI models
  • Experiment and deploy AI copilot and self-driving solutions at scale to improve agent productivity and/or eliminate manual decision loops altogether
  • Work with embedded Machine Learning Engineers on the team and ML platform services to deploy models to the production environment and monitor ongoing performance
  • Use Python ML stack, LLMs, PyTorch, Snowflake, Airflow-based tools, and cloud services (both GCP & AWS)

You have:

  • 4+ years of Machine Learning modeling experience. Full-stack ML experience
  • A Bachelor's degree in computer science, data science, operations research, applied math, stats, physics, or a related technical field
  • End-to-end experience building and deploying ML to production systems (batch and real-time) that are performant at scale
  • Experience with advanced ML techniques like large language models, embeddings, sequence modeling, and graph convolutional networks
  • Experience of independently driving programs with multiple cross-functional stakeholders (e.g., Engineering, Product, and Country leads) that have business impact
  • Have a curious, growth-oriented mindset and the ability to think in first principles to identify creative solutions that demonstrate value
