Achieve least possible latency. - Write Python scripts and internal tooling to automate repetitive tasks and improve operational workflows - Collaborate closely with engineering and ML teams to support product infrastructure, internal platforms, and compute-heavy workloads when needed YOU’LL FIT RIGHT IN IF : - You have hands-on experience with AWS services such as IAM, S3, EKS, and ECR - You’re comfortable working not only in cloud environments, but also with real production on-prem infrastructure - You have strong Unix/Linux fundamentals and can confidently troubleshoot, tune, and operate systems in production - You’ve worked with containers in real environments and understand how to build secure, efficient setups - You have practical experience and fundamental knowledge with Kubernetes, whether in EKS, k0s, or similar distributions - You’ve built or maintained real CI/CD pipelines and understand how to make deployments reliable - You understand networking well, including TCP/IP, routing, firewalls, and load balancing - You have solid Terraform and Infrastructure-as-Code experience - You’ve worked with Datadog for monitoring and observability - You use Python comfortably for automation and internal tools - You communicate clearly and work well with others. Fluent English. A big plus: - Experience with machine learning or GPU workloads. - Experience with multi-cluster or multi-cloud environments. - Exposure to security-focused infrastructure, air-gapped environments, or locked-down systems. ## WHY WHITE CIRCLE - Meaningful equity package - Paid time off in line with your local regulations, no matter where you work from - Work from Paris (hybrid) + relocation package - Best medical insurance in France - All the hardware, tools, and services you need - Covered subscriptions for AI agents and IDEs - Team off-sites twice a year: we’ve recently been to the Alps and to Saint-Tropez ## HOW WE HIRE 1.
