  • Full-time

Company Description

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.

Job Description

Square's Security culture is focused on helping our engineering teams build and ship secure products. We achieve this by designing, building, and operating state of the art security alongside our product and infrastructure teams.

The Software Supply Chain Security workstream within Infrastructure Security is focused on ensuring that the code Square ships is as secure as possible.
