This role is part of our Cash App's ML team and will be deeply embedded within one of our product teams - here are the workstreams we're currently hiring for:
Search & Discovery
Cash App enables millions of people and businesses to pay and get paid with ease. On this team, you will build delightful experiences that help our customers find and discover people and things quickly and with trust - we aim to grow and strengthen the connections between people and businesses across the globe. Through your work, you will empower Cash App to personalize customers’ search and discovery experiences using AI/ML, to better understand our customers’ payment journeys, and help identify and execute on new opportunities for product improvement. You will employ a variety of modeling techniques on our comprehensive customer data and scale your solution to production by partnering closely with design, product, analytics, and engineering teams.
Recommendations + Incentives
We provide an ML-powered recommendation services platform that works for the entire gamut of our Product Abstractions and enables Cash to make creative and personalized customer experiences. Furthermore, our ML models used for incentives programs consistently provide value to the business and our customers by attracting and engaging more customers which directly contributes to the massive success of Cash.
Risk
You'll build machine learning models that detect fraudulent activity in real time and help keep our customers safe and secure. You will experiment with state-of-the-art algorithms to drive down false positives, collaborate on new product features to drive fraud losses down, use any and every dataset at your disposal (including 3rd party data) to engineer new features for risk models, verify customer documents using OCR, and use biometric and device signals to detect malicious logins and account takeovers.
Risk AI
We are a group aimed at developing deep learning based signals and learned representations for Risk ML models. Currently, Risk @ Cash ML models are predominantly based on tabular supervised tree-based models. Our team has the mandate to explore and implement alternatives based on SOTA neural network architectures and techniques. This is a particularly exciting time to join as you will be part of the first members of the team, and will have the opportunity to shape our roadmap.
Customer Support Automation
We aim to create better-than-human Customer Support Experiences. Cash App holds people’s money, and building customers’ trust is absolutely essential to our brand. Providing fast and reliable help whenever the customer needs it is a major component of building that trust. You will build models that anticipate customer issues and deliver proactive in-app suggestions, use NLP to contextualize inquiries and respond instantly with relevant content, develop prioritization algorithms that improve efficiency, and apply the latest research to automate conversations with customers.
Underwriting and Credit
Our mission is to redefine credit and liquidity through simple, fair, and accessible credit solutions that build financial health and resilience. This team builds and integrates ML solutions for evaluating customer cash flow risk including risk of default on credit obligations, risk of fraud & abuse of loans and other situations where Cash app advances funds or provides liquidity to customers. We support multiple products across 4+ workstreams in Cash. Through your work you will empower the team to understand the financial performance of origination cohorts, optimize our automated decisioning pipeline using AI/ML, and help identify new opportunities for growth in our customer base. You will experiment with various modeling techniques on our comprehensive customer data and see your solution through to production by partnering cross-functionally with finance, product, and engineering teams.
