Product Security Engineer

Seattle, WA, US April 15, 2026

We believe that the way people interact with their finances will drastically improve in the next few years. We’re dedicated to empowering this transformation by building the tools and experiences that thousands of developers use to create their own products. Plaid powers the tools millions of people rely on to live a healthier financial life. We work with thousands of companies like Venmo, SoFi, several of the Fortune 500, and many of the largest banks to make it easy for people to connect their financial accounts to the apps and services they want to use. Plaid’s network covers 12,000 financial institutions across the US, Canada, UK and Europe. Founded in 2013, the company is headquartered in San Francisco with offices in New York, Washington D.C., London and Amsterdam.

The Product Security team is responsible for the processes, policies, controls, and engineering systems that secure Plaid’s developer- and consumer-facing products. The team focuses on areas including application security, vulnerability management, secure development lifecycle, penetration testing, and cloud security. Beyond setting standards, the team builds the services, components, and workflows that protect Plaid’s products at scale. By moving security “left,” Product Security makes the secure path the easiest path for engineers across the company.

Plaid is looking for a Product Security Engineer who is fundamentally a builder. Unlike traditional product security roles, this position is designed for a software engineer who wants to solve security challenges at scale by developing production-grade services, libraries, and frameworks. In this role, you’ll build and maintain Plaid’s vulnerability management orchestration service, automate workflows to reduce operational toil, and create solutions that eliminate entire classes of vulnerabilities. You’ll also partner closely with product engineers to ensure services meet security standards, support incident response and security awareness efforts, and collaborate across the security platform organization to deliver the engineering foundations that make secure development the default at Plaid.
