Senior Associate, Data Scientist - US Card (Applied GenAI)

Data is at the center of everything we do.

The Servicing Intelligence team delivers data science solutions to capture value from unstructured, multi‑modal data sources — text, image, and audio data. The team is an applied data science group building with open source generative AI models and tooling, focusing on application over research to scale the adoption of AI with in‑market solutions.

As a core member, you will be a driving force to create best‑in‑class products and experiences powered by the latest emerging generative AI technologies.

• Apply expertise in unstructured data (text, image) to harness the power of open source large language models (LLMs) and visual language models (VLMs).
• Leverage a broad stack of technologies such as Lang Graph, Llama Index, Weights & Biases Weave, Hugging Face, PyTorch, AWS, and more to automate workflows using huge volumes of text and vision data.
• Build machine learning and NLP models through all phases of development, from design through training, evaluation, and validation; partner with engineering teams to operationalize them in scalable and resilient production systems serving 80+ million customers.
• Assess GenAI or LLM‑powered application architectures in production, including best practices for generative AI development and deployments.
• Define requirements for AI observability, focusing on traceability of autonomous decisions and comprehensive system audit trails.
• Evaluate the dynamic behavior of AI systems and oversee the development of key continuous monitoring controls and testing, ensuring non‑deterministic outputs and autonomous actions remain within risk appetite.
• Guide annotators to curate high‑quality, consistent datasets for model training, evaluation, and ongoing AI monitoring.
• Collaborate with a team of data scientists through all phases of project development, from design through training, evaluation, validation, implementation, and maintenance.
• Interact with a variety of internal stakeholders to ensure alignment of data science solutions with business outcomes.

• Currently holds, or is in process of obtaining, a Bachelor’s Degree in a quantitative field (Statistics, Economics, Operations Research, Analytics, Mathematics, Computer Science, or a related quantitative field) plus 2 years of experience performing data analytics.
• Or a Master’s Degree in a quantitative field (Statistics, Economics, Operations Research, Analytics, Mathematics, Computer Science, or a related quantitative field) or an MBA with a quantitative concentration, with the required degree obtained on or before the scheduled start date.

• Master’s Degree or PhD in a STEM field (Science, Technology, Engineering, or Mathematics).
• Experience working with AWS.
• At least 2 years’ experience in Python, Scala, or R.
• At least 2 years’ experience with machine learning.
• At least 2 years’ experience with SQL.
• At least 2 years’ experience with AI/ML tools and ecosystems such as Lang Graph, Llama Index, Weights & Biases Weave, PyTorch, or Hugging Face.
