Machine Learning Engineer
About the job
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 Capital, 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 Engineer within the Risk Machine Learning team, you will lead projects that enable a software driven, machine learning centric view on all money movement and every transaction within the rapidly growing Square seller 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.
- Lead and drive cross functional machine learning projects from beginning to end: build relationships with partner teams, frame and structure questions, collect and analyze data, research, prototype, and build out machine learning pipelines, and runtime services of models in production.
- Collaborate with business leaders, subject matter experts, and decision makers to develop success criteria and optimize new products, features, policies, and models
- Build a strategy of how various machine learning driven solutions come together against a team and technical product strategy.
- 5+ years industry experience in software engineering or machine learning-focused roles.
- An advanced degree (M.S., PhD.), preferably in Computer Science, Electrical Engineering, Statistics, Physics, Mathematics or a related technical field.
- A strong track record of performing machine learning model development using Python (numpy, tensorflow, pytorch, scikit-learn, etc.) and SQL/NoSQL interaction patterns.
- 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.
- 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
- Machine learning strategic sequencing of methodological and software improvements to work back from maximizing core metrics associated with optimizing the business.
- The ability to clearly communicate complex results to technical and non-technical audiences.
