About Cinder

Cinder is the mission-critical infrastructure that keeps the world's most important digital platforms true to what they stand for. The internet has always been abused by bad actors, and AI is making it exponentially worse, driving fraud, abuse, and manipulation at a scale and speed no human team can fight alone. Cinder gives platforms one command center to fight back: to write and enforce policy, deploy AI agents against abuse in real time, investigate threats, file NCMEC reports, and prove their safety programs are working.

Our customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.

We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.

Why this role

Most companies building with generative AI don't know yet that they have a trust and safety problem. They will soon, and Cinder is the infrastructure they'll run on when they do. Right now, that story lives only with our current customers, and getting it in front of the right people before they know they need it is the job.

You'll work closely with our existing marketing team to make that happe
