Top SchoolPierre Cheynier is a Senior Staff Site Reliability Engineer with 12+ years of experience designing and industrializing large-scale, high-availability platforms for millions of customers. Based in France, he has led automation and self-service provisioning for one of the world’s largest retargeting infrastructures—managing multi-DC fleets of tens of thousands of servers and trillions of daily HTTP requests. His expertise spans cloud-native transitions, Kubernetes and KubeVirt, network disaggregation with eBPF/Cilium and EVPN, and pragmatic API-driven "as-a-Service" platforms that reduce TTD and TCO. He combines deep networking knowledge (routing, overlays, load-balancing) with software-focused automation in Python and Go, and a strong UX sensibility for internal developer workflows. Notably, he shepherded major shifts from proprietary appliances to commodity hardware and OSS stacks while maintaining extreme scale and reliability. He is drawn to technically ambitious, innovative projects where infrastructure efficiency and operational simplicity matter most.
