Cosuno is hiring a Head of Platform & Security to take full ownership of the infrastructure, security, and compliance foundations our product is built on. You'll be a key partner to our CTO and Engineering team, ensuring we stay secure, certified, and scalable as we grow.
What You'll Do
- Complete 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
What We're Looking For
- Full professional fluency in German and English — a significant part of our compliance and customer-facing security work is conducted in German
- Hands-on experience with ISO 27001 — you've led or been deeply involved in a certification and know how audits actually work
- Solid experience with cloud infrastructure (AWS and/or GCP) and infrastructure-as-code (Terraform)
- Comfort operating Kubernetes in a production environment
- The organisational maturity to manage multiple open threads — an audit, an RFI, an infra task — without things slipping
- A pragmatic, ownership-driven mindset: you find both the technical and operational sides of this role interesting
Nice to Have
- 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
- Prior experience at a B2B SaaS startup
Technical Stack
- Terraform
- AWS
- GCP
- Kubernetes
Team & Environment
You'll be a key partner to our CTO and Engineering team, reporting directly to the CTO.
