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 exists
We don't have an open role for everyone who'd be great at Cinder. This is for the people we'd regret not talking to anyway.
If you've read through our open roles and nothing quite matches your background, but you think there's a reason you should be working on trust & safety infrastructure, this is where you tell us.
What to send us
Please share your resume and a cover letter that includes:

What you'd actually want to do here, specifically. Not "anything" — a role, a problem, a team.
-
Why Cinder, not just "an interesting company." What about this problem space pulls you in.
-
One thing you've built or shipped that we should know about.
