Founding Product Marketer

Cinder•San Francisco, CA

25d

About The Position

Cinder provides a cutting-edge platform to protect the internet. Cinder safeguards the interaction layer: the front end of products that users engage — and sometimes abuse. Our AI agents, integrated workflow platform, and deep expertise power real-time integrity at the speed of innovation. We support some of the most important and innovative companies in the world, including OpenAI, Midjourney, and ElevenLabs. Cinder is backed by Accel and Y Combinator. We care deeply about being relentless, intentional, and empathetic. We hire gritty thinkers who set ego aside, aggressively solve customer problems, and get better every day. Cinder is seeking a founding Product Marketer to join our team. We’re building an enterprise-grade platform to make the internet safer and we need highly curious, hard-working self-starters. This role is based in New York and will involve close collaboration with Cinder's teams in London and San Francisco. We also believe in the value of frequent in-person meet-ups and learning face to face. We offer health, vision & dental benefits and a 401(k) plan with employer matching. We are interested in exceptional candidates in London or San Francisco, but New York City is preferred. Cinder is hiring our first full-time marketer. That’s going to require a creative, highly-motivated professional willing to take risks, embrace ambiguity, and take on highly strategic and highly tactical tasks. In this job, you will do it all. If that’s not exciting; don’t apply. You will own all marketing functions — from positioning and product marketing to demand generation, content— and build the foundation for scalable growth as we expand our footprint across the AI ecosystem. This is a role for someone who dives deep into complex technical problems, thinks strategically, and executes quickly. You will work directly with Cinder’s executives, customers, and partners to translate sophisticated AI-driven capabilities and solutions into clear, compelling narratives. Cinder is both unprecedented software and the tool people use to do their jobs everyday. You’ll need to think out-of-the-box and very practically. Bottom line: there will be no better opportunity to define how integrity is integrated in modern enterprise to drive innovation.
