Platform Engineer (AWS)

Own the cloud infrastructure on AWS for ai-coustics' platform. You will be the single accountable owner of this platform: its reliability, security, cost and the deployment pipelines the engineering teams rely on. You report to the CTO and work daily with the backend lead and our IT operations engineer.

What you'll do

• Own the AWS infrastructure end to end: Terraform, multi-account setup, networking, IAM, EKS, databases, CDN
• Run the Kubernetes stack: service mesh, certificates, secrets management, autoscaling, upgrades
• Own observability for the platform: metrics, logs, alerting and the dashboards teams operate from
• Build and maintain the CI/CD pipelines and deploy roles for our backend and frontend services
• Implement and maintain the technical controls for SOC 2 and keep the evidence current
• Plan capacity for continued fast growth and own platform cost
• Be on-call for the infrastructure, write runbooks and run incident reviews

What you'll need

• 5+ years running production infrastructure on AWS with Terraform
• Deep EKS experience: node pools, autoscaling, networking and IP planning, upgrades, workload placement
• Certified Kubernetes Administrator (CKA) or AWS Certified CloudOps Engineer – Associate (formerly SysOps Administrator), or both
• You design IAM and access with least privilege and can explain your decisions to an auditor
• You have been the single accountable infrastructure owner at a company, not one engineer in a large SRE team
• Strong Linux, networking and debugging skills across the stack
• You automate everything repeatable and treat infrastructure changes like code: reviewed, tested, reversible
• You use AI coding tools daily and know where they help and where they don't

Nice to have

• SOC 2 or ISO 27001 controls and evidence work, Istio, Temporal, GitHub Actions with OIDC, cost optimization, CloudFront and WAF

What they offer

• Competitive package with stock options
• Small team with direct access to founders and full ownership of your area
• Berlin office with hybrid setup and trust to ship fast
• World-class team of engineers and researchers with room for professional growth
