Security Engineer

Engineering Contract Remote

About the role

Count My Boxes is multi-tenant. You will review auth, portal tokens, file links, and admin paths for cross-tenant access, and you will keep the dependency and header bar from drifting. Remote contract. Findings go to engineering with a reproduction, not a slogan.

What you'll do

  • Review changes that touch login, portal access, uploads, or tenant filters
  • Retest a reported cross-tenant or IDOR issue yourself
  • Track vulnerable packages and the ones we actually ship
  • Write the customer-facing answer when we are asked how data is separated

What we're looking for

  • You have done application security or a security-minded engineering role on a multi-tenant app
  • You can explain a finding to someone who will fix it

Nice to have

  • ASP.NET, OAuth, or signed customer links
