The Platform & Infrastructure Engineering team in the Data Infrastructure organization is responsible for the reliability, scalability, and security of the company’s data platform. The team builds and operates the foundational systems that power data ingestion, transformation, analytics, and internal AI workloads  operate with production-grade discipline, supporting mission‑critical services with stringent uptime requirements and a focus on automation, observability, and resilience.

As a Senior Site Reliability Engineer, you will own the reliability and performance of our Kubernetes‑based data platform. You will design and operate highly available, multi‑region systems, ensuring our services meet strict uptime and latency targets. Day‑to‑day, you’ll work on scaling infrastructure, improving deployment pipelines, and hardening our security posture. You’ll play a key role in evolving our Dev Sec Ops  practices while partnering closely with engineering teams to ensure services are built for reliability from day one.
