David Roy
Principal TME at Juniper Networks
Rennes, Brittany, France
Summary
👤
SeniorDavid Roy is a Principal Technical Marketing Engineer at Juniper Networks with a two-decade foundation in networking and telecom and nine years of documented professional experience in roles bridging engineering, product, and field support. He combines deep carrier-grade expertise in routing, MPLS/Segment Routing, multicast and virtualized network functions with hands-on skills in automation, telemetry and observability (gNMI/gRPC, Netconf/YANG, InfluxDB/ClickHouse, Grafana). A former Orange backbone and R&D engineer, he authored multiple MX-focused books and patents and contributes to open-source projects around provisioning and analytics, pairing protocol-level insight with practical software tooling in Python and Go. Based in Rennes, France, he is as comfortable defining hardware/software specs with PLM as he is debugging packet flows on high-capacity PTX/MX platforms. An uncommon strength is his cross-domain fluency—from low-level audiovisual transport and IPTV standards to modern API-driven network analytics—enabling him to translate operational realities into product direction.
