Build security platforms, not security processes

We are looking for a Staff Security Engineer to strengthen the security of our products, data and engineering platform.

This is a highly technical and hands-on role. You will work closely with Engineering teams to continuously harden our systems while helping design the next generation of our security architecture.

You will operate across two horizons:

Strengthen security today: continuously harden our applications, access controls and data-protection mechanisms against evolving threats.
Build the privacy architecture of tomorrow: move beyond traditional perimeter and access-control security by designing systems where sensitive data is cryptographically isolated, minimally exposed, and increasingly usable without being directly revealed.

The ultimate objective is not simply to make Swile harder to breach. It is to make a breach increasingly uninteresting, because there is less usable data available to steal.
