Requirements

• In your first few months, you might: • Lead our ISO 27001 certification and establish the processes to maintain it going forward • Take ownership of our Terraform configurations across AWS and GCP, improving structure and reliability • Respond to security questionnaires from enterprise customers, helping us close deals faster • Streamline employee IT onboarding and access management across our SaaS tooling stack • Set up and manage MDM, tooling, and IT support for the team • Full professional fluency in German and English — a significant part of our compliance and customer-facing security work is conducted in German, and this is a firm requirement • Solid experience with cloud infrastructure (AWS and/or GCP) and infrastructure-as-code (Terraform) • Comfort operating Kubernetes in a production environment • The ability to pick up new domains quickly — whether that's navigating an ISO 27001 audit or setting up an MDM solution, you figure things out by thinking clearly, not by having done it ten times before • A pragmatic, ownership-driven mindset: you're equally comfortable debugging a Kubernetes issue and writing a security policy • The organisational maturity to manage multiple open threads — an audit, an RFI, an infra task — without things slipping • Experience with ISO 27001 or other security certifications • Experience with compliance automation tooling (Vanta, Drata, Kertos, or similar) • Familiarity with GDPR operational requirements (DPAs, DSARs, vendor reviews) • CI/CD experience, including self-hosted runners
