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. We’re building an enterprise-grade platform to make the internet safer and we need highly curious, hard-working self-starters. The Role Cinder is hiring our first full-time marketer - someone who’s excited to build from scratch, move quickly, and help define how a category-creating product is understood in the world. This is a deeply hands-on role. You’ll be the person who translates complex, technical AI-driven capabilities into stories people instantly “get.” You’ll bring clarity to a space that’s advancing quickly, and you’ll shape how customers, prospects, and the broader market understand Cinder’s platform and the problems we solve. As our Founding Marketer, you’ll move between strategy and execution every day. As our brand expands, you’ll help position us in a rapidly evolving market by translating customer perspective, user insights, and practical context into clear, compelling storytelling across channels, teams, and audiences. You will manage the creation of content that helps people understand what Cinder does and why it matters, enabling our GTM teams with strong materials, and helping establish how we show up publicly. You will collaborate closely with Product, Engineering, Sales, and the founders. This role is ideal for someone who has had significant ownership in an early-stage startup and feels energized by the ambiguity and pace of building something new. Bottom line: there will be no better opportunity to define how integrity is integrated in modern enterprise to drive innovation. This position is based in New York City.
