Machine Learning Manager, Fraud Risk
- Seattle, WA, USA
- Employees can work remotely
- Alternate Location: Seattle, United States
Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Loans, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.
As a Machine Learning Manager within the Risk Machine Learning team, you oversee projects that enable a software driven, machine learning centric view on all money movement and every transaction within the rapidly growing Square ecosystem. This touches on actively maximizing the trade off of revenue growth and risk using artificial intelligence. The machine learning driven software that we release interacts with every transaction and money movement within our seller ecosystem - a profound degree of scale and impact. Such machine learning techniques touch on reinforcement learning, decision theory, deep learning sequence modeling, and optimization theory. In addition, we also strive to provide our sellers, through seller facing products, with transparency around why our machine learning made a particular decision. This touches on algorithms in the relatively new space of explainable artificial intelligence.
Our algorithms derive value from our unique and rich data from our entire product portfolio within our rapidly growing seller ecosystem. We partner with business, product, operations and engineering teams to drive optimal decision making systems using sophisticated modeling and machine learning. We’re a passionate team of entrepreneurs, scientists, and engineers who are shipping machine learning software that actively actively manages Square’s view on each transaction as it pertains to our revenue growth and risk.
- Provide technical and functional guidance to the team of ML Modelers to build and deploy machine learning/deep learning models that detect fraud activity in real time across our Seller's ecosystem consisting of payments, banking and debit card products.
- Work with engineers and stakeholders to build a team roadmap and coordinate many large, cross functional projects.
- Collaborate with business leaders, subject matter experts, and decision makers to develop success criteria and improve new products, features, policies, and models
- Define ML best practices and ensure the team follows them
- Define and guide the ML strategy to help the broader Fraud organization meet their OKR's
- Drive efficiencies through automation and optimization
- Experience leading a high performing ML modeling team with a minimum of 2 years of people management responsibility
- An advanced degree (M.S., PhD.), preferably in Computer Science, Engineering, Statistics, Physics, Mathematics, or a related technical field.
- PhD. with 3+ years (or Master with 6+ years) industry working experience on applied Machine learning or Deep learning
- A strong track record of performing machine learning model development using Python (numpy, pandas, tensorflow, pytorch, scikit-learn, etc.) and SQL/NoSQL interaction patterns.
- Knowledge of modern techniques in machine learning and deep learning, e.g., transformer network architectures, with an orientation to maximizing such algorithms in a large scale production setting. Reinforcement learning experience is a plus for developing optimal control policies
- Familiarity with Linux/OS X command line, version control software (git), and general software development principles with a machine learning software development life-cycle orientation.
- Experience defining and driving the Machine Learning strategy to help organizations/teams meet their OKR's
- The ability to clearly communicate complex results to technical and non-technical audiences and stakeholders (PMs, Operations, Engineers).
