Cinder helps high-growth companies design, automate, and scale modern trust and safety operations. Backed by Accel.
About the role
Own end-to-end design for assigned surfaces, from framing the problem to shipped UI, working directly with product and engineering. Run discovery with product: talk to Trust & Safety customers and users, and turn what you hear into design direction and Linear tickets an engineer can pick up and build from.
What they're looking for
- Strong visual and graphic design craft: the eye to judge quality, and the ability to produce clean work without leaning on AI tools
- 6+ years designing software at senior to staff level, with real depth on technical products built for expert users
- Expert in Figma: wireframing, flows, prototyping, and production-grade delivery
- Fluent with AI coding agents (Cursor, Claude, Codex) for designing and prototyping, not just experimenting with them
- A high tolerance for ambiguity. You can create your own clarity and make calls without a finished PRD or research
- Proactive by default. You flag and fix design debt before anyone asks you to
More about this role
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.
Cinder's product surface is expanding fast: new agent-facing workflows, multiple product lines, and a growing brand and GTM footprint. We're building out design to match, and we're looking for a second senior designer to own significant surfaces end to end.
