Trust, Safety, and Responsible Engineering

This module covers Roblox's massive investment in trust and safety -- from their $143.4 million annual safety budget to the open-source Sentinel AI system that detected 1,200 potential child endangerment cases in the first half of 2025. Safety is not a side concern at Roblox; it is a core engineering discipline and cultural value. Candidates who cannot articulate how safety considerations influence their technical decisions will struggle in behavioral rounds.
