Job description

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.

Why work at Cinder

  • Mission-Driven Work: Employees tackle urgent, high-stakes problems like deepfake nudes, child sexual abuse material, AI-generated phishing campaigns, and organized crime. The work is described as "urgent, visible, and high-stakes."
  • Fast-Paced Culture: The company ships in days, not quarters, and makes decisions with incomplete information. Speed is not optional because adversaries are moving fast with AI.
  • Values: "Own the Outcome," "Ship Relentlessly," "Mission Over Ego," and "Customer Obsessed." The team is deliberate about building a diverse group with different backgrounds and perspectives.
  • Work Policy: Hybrid; based in New York City with team members across the US and UK/EU. The company holds at least two all-company gatherings per year and is especially focused on hiring in NYC, with relocation support for the right candidates.
  • Benefits: Competitive health, vision, and dental coverage; 401(k) with employer matching; paid family leave; flexible paid time off; fully paid commuter benefits; and a fully stocked NYC office with paid lunch and dinner.
