We are seeking backend engineers that have an interest in solving highly adversarial problems with real-time systems and data, as we blend AI agents with the data they need to keep online platforms safe. You'll be responsible for building core API infrastructure for interfacing with AI systems, working across our entire tech stack from our backend services to frontend, managing and scaling real-time infrastructure that currently warehouses events and signals, and working on our backtesting and simulation infrastructure to re-play historical attacks and abuse patterns.
