Security Partner, Platform and Infrastructure Engineering

  • San Francisco, CA
  • Employees can work remotely
  • 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

Our Security Partners identify risks to our ecosystem, determine our product security roadmap, and guide security architecture in collaboration with teams across Square. Security Partners' work is an important input to our security strategy, to our prioritization of security engineering work, and to the protection of our buyers, sellers, and company.

We are looking for a security partner to grow our coverage to our Platform & Infrastructure Engineering (PIE) team. You will work with business and engineering leaders to scale our security practices and enable the Platform and Infrastructure teams to ship products that are both remarkable and secure.

  • Foster a security culture within PIE focused on enablement and a deep understanding of what it takes to develop great products.
  • Partner with our Security Program Management Office (PMO) to measure and prioritize security risks to our buyers, sellers, and the company to ensure we're applying our resources to the most pressing concerns, resulting in establishing overall Security strategy and prioritization at Square.


You have: 

  • 8+ years of experience establishing and scaling security practices in modern technology company environments with a combination of cloud, SRE, and security.
