What you will do

What you will work on

Build models that recommend the most suitable payment method for each customer—for example installments, cards, or local payment options—and identify the right customers to reach, balancing customer preference, cost, and risk.
Take models to production behind a real-time, low-latency personalization layer that serves live shopping traffic at scale.
Build multi-agent generative-AI systems that turn unstructured inputs—customer feedback, documents, and operational data—into reliable, decision-ready insight, with verification that guards against model hallucination.
Help customers discover and adopt installments and alternative payment methods.
Design and analyze large-scale online experiments and causal measurement to validate real customer and business impact.

Key job responsibilities

Design, develop, and evaluate machine learning and deep learning models, and deploy production-ready solutions to complex customer and business problems.
Conduct rigorous scientific research: form hypotheses, run experiments, evaluate model performance, and iterate on approaches within your domain of expertise.
Write clean, maintainable, and efficient code that integrates smoothly into larger systems and meets a high bar for operational excellence.
Partner with engineering to take your models to production, and with scientists across related payments ML teams to solve shared, complex problems.
Contribute to team roadmaps, priorities, and technical direction; mentor peers and provide constructive feedback on research and code.
Publish at peer-reviewed venues and file patent applications where appropriate.

A day in the life

You will start your day reviewing experiment results and refining model architectures based on new insights. Throughout the day you will alternate between writing research code, analyzing data, and discussing technical approaches with teammates, working closely with engineering to build your ideas and take them to production. You will regularly present findings and propose new ideas, and you may write research papers and submit patent applications.
