Application Security Engineer (Berlin/hybrid)

Application Security | Secure SDLC | AWS | SAST/DAST | Threat Modeling | Vulnerability Management | ISO 27001 | GDPR

We build ETERNO Cloud, the operating system for modern medical practices. It brings the core workflows of a medical practice into one cloud SaaS platform. The product handles sensitive healthcare data in a regulated, GDPR-compliant, and ISO 27001-certified environment, so security needs to be part of how we build, ship, and operate software.

You are the main AppSec owner inside engineering, working closely with ISMS, Cloud Platform, and Tech Leads to make application security actionable in product development.
