  • Atlanta, GA
  • Employees can work remotely
  • Full-time
  • Alternate Location: Toronto, Canada

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 Information Security culture is focused on enabling our engineering teams to build and ship secure products. We achieve this by designing, building, and deploying state of the art security alongside our product and infrastructure teams.

The Software Supply Chain Security team, within Infrastructure Security, is focused on ensuring that the code Square ships is as secure as possible. We blend third-party tooling with in-house systems to improve the security of many types of code including backend, frontend, infrastructure, and mobile.

You will:

  • Harden Square’s build systems and overall software supply chain by designing, architecting and building security services. Your work leading the implementation of security systems will have a broad impact across Square’s software development organization, securing the critical systems for delivering our products.

  • Partner with groups across the company to secure multiple different CI and build systems (notably for web apps, mobile apps, hardware, etc) and programming languages. 

  • Collaborate with software engineers across the company to implement solutions that “grease the wheels” of security best practices from commit to artifact

  • Work remotely or in any Square office location in the USA or Canada. Occasional travel may be required for team offsites after the pandemic. SSCS is a fully distributed team.

  • You have experience securing multiple different build & CI systems and have interest in or experience with build attestation systems. You are also familiar with the software development process and have worked closely with engineers.

  • You are familiar with at least one cloud platform (AWS, GCP, etc) or on-prem infrastructure deployments.

  • You have experience writing code to solve security issues. This could be writing security tools, integrating security into products, or automation/management of security-sensitive environments.

  • Interest in Software Supply Chain Security (no experience required)
