Product Security Engineer
We are looking for a Product Security Engineer to join the team responsible for securing Action1’s multi-tenant SaaS product.
In this role, you will work closely with engineering, product, and security teams to identify risks early, support vulnerability handling, improve secure development practices, and help make product security practical, clear, and actionable.
This is a hands-on role for someone who understands both software engineering and cybersecurity, enjoys working directly with developers, and wants to help build security into the product without slowing teams down unnecessarily.
