About this role:

Faire operates at serious scale — a global marketplace handling real money movement, sensitive business data, and the financial futures of hundreds of thousands of independent retailers and brands. Security here isn't a compliance checkbox. It's a core part of how we build, and how we grow.

We've built solid security foundations. Now we're looking for someone to take them to the next level — designing the architecture and automation that lets product engineers build securely by default, without friction. If you're energized by the challenge of making security invisible to developers while making it impossible to skip, this role was written for you.

Our Engineering organization owns the software that makes our marketplace work. Our Product Security team enables product engineering teams to develop and deploy secure software that makes that happen. We care about good engineering practice and love to write software that is secure, tested, easy to maintain, and can scale to millions of users. We build scalable, reusable frameworks; consult with product teams; listen to the data; and iterate.

As a Senior Staff Software Engineer, Product Security, you'll be the technical lead for the Product Security domain — owning the long-term direction for how security is designed, built, and automated across Faire's entire application stack.
