About the role

As Lead Security Engineer, you'll own application security across our platform, embedding secure practices into how we design, build, and ship software, and setting the direction for a growing security function.

 - Support customer security reviews and compliance (SOC 2, HIPAA, GDPR) with practical technical controls.

 - Mentor engineers and raise the security bar across the organisation.




What we're looking for

 - 7+ years in software or security engineering, with significant hands-on AppSec experience.

 - Strong coding ability (Python and/or TypeScript ideal) and the cred
