Own the ML roadmap that catches Roblox outages before 100M daily users feel them
Roblox is hiring its first Senior ML Engineer inside the Reliability team, tasked with using anomaly detection and time-series modeling across logs, traces, and metrics to cut Mean Time to Detect and Mean Time to Resolve production incidents. This interview probes applied ML for systems reliability, distributed-systems fundamentals, and the judgment to set technical direction in an ambiguous, first-of-its-kind role.

How would you reduce MTTD/MTTR using ML rather than static thresholds
Build a time-series model to predict capacity exhaustion before it happens
How do you avoid alert fatigue / false positives in an automated detection system
Tell me about a time you set technical direction with no existing playbook
How would you explain a complex ML reliability system to non-technical executives
