About this role
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.

About this listing
Published on Ashby under the board identifier Cinder, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
Published 5 August 2026, last checked about a month ago. A posting stops being advertised here 90 days after the employer published it, and one the employer takes down is marked closed rather than quietly removed.
