About The Position

As a Senior Data Reliability Engineer on the Ricochet Anti-Cheat team for Call of Duty, you will play a critical role in building and operating the data systems that power Call of Duty Anti-Cheat. This involves processing petabytes of game telemetry with high reliability, integrity, and trust. You will design, deploy, and operate large-scale, reliable data systems that support telemetry ingestion, enrichment, and analytics for Anti-Cheat. Working closely with Machine Learning, Security, and Game Engineering teams, you’ll help enable automated data pipelines—from ingest to insight—that directly inform anti-cheat actions in production. This role blends data engineering, reliability engineering, and operational excellence. You’ll define GitOps-based workflows for securely deploying data pipelines and application stacks, build deep observability into everything you own, and ensure the accuracy and validity of data that Anti-Cheat systems depend on.
