Hybrid Full-time

Cosuno is hiring a Head of Platform & Security

About the Role

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.

Benefits & Compensation

  • Competitive Compensation: A competitive salary above the market average, ranging from €80K - €100K.
  • Work-Life Balance: Choose to work 100% remotely or from our modern office in Berlin. We offer flexible working hours.
  • Top-Notch Equipment: A new MacBook Pro.
  • A Great Team: Regular company off-sites and team events.
  • Job Security: A permanent contract in a stable, well-funded company.

Work Mode

This is a hybrid role based in Berlin.

We believe in diversity because we know that the best ideas come from different perspectives. An integrative and inclusive work environment is a matter of course for us.
