As a Senior Backend Engineer you will be responsible for work on core production code that can include distributed systems work and implementing or optimizing machine learning paths. You will improve and drive our evolving systems, threat models, and CI/CD practice.

Using AI: Coding agents are indisputably useful tools. We provide access to the top 3 models, and were early adopters of evals-first development flows. Familiarity with coding using agents is part of all interviews. However, reliability and correctness are critical for us. You will need to read and understand every line of code with your name on it, and it will be reviewed by both people and machines.
