ABOUT THIS ROLE This isn't one of those roles where security means running scans or writing policies that gather dust.

We're looking for a real engineer — someone who thinks like a builder and a breaker.

Someone who gets deep into the stack whether it's an API endpoint a container image or a browser sandbox.

You know how things are supposed to work — and what happens when they don't.

While some security professionals lean toward policy compliance or audits (and we value that too) we're after someone who wants to write code secure systems dig into strange bugs and harden the platform from top to bottom.

This is not a role for pointing out what needs to be done.

It's for someone who's ready to do it.
