Founding Marketer at Cinder

About Cinder

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 build campaigns, not decks. You’ll ship quickly, test messages, iterate in public, and use data and user behavior to guide decisions. You’ll bring clarity to a space that’s constantly evolving, and you’ll shape how customers, prospects, and the broader market understand our platform and the problems we solve.

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 and improve the internet.

This position is based in New York City.

What You’ll Do

Product Marketing

• Translate customer problems into simple, compelling narratives that resonate with both technical and non-technical stakeholders.

• Partner closely with Product, Engineering, Sales, and the founders to support go-to-market strategy for new features, capabilities, and product iterations.

• Turn performance analytics and customer research into actionable business insights.

Content, Storytelling & GTM Enablement

• Shape an editorial voice that feels human, accessible, and grounded in real customer insight.

• Create high-quality content that helps customers, prospects, and the broader market understand what Cinder does and why it matters. This includes blog posts, launch narratives, technical explainers, and customer stories.

• Build materials that help Sales and Customer Success communicate Cinder’s value clearly, including decks, one-pagers, messaging guides, and product overviews.

• Partner with GTM teams to test messaging, identify where clarity is needed, and iterate quickly based on feedback from the field.

Brand & Early Stage Ownership

• Partner with founders to evolve Cinder’s brand identity across all channels and ensure that it reflects our product, values, and customers.

• Serve as the primary marketing point of contact for our external brand and website redesign partner. Help shape creative direction, provide thoughtful feedback, and keep the work aligned with our narrative.

• Establish lightweight processes for launches, messaging tests, and gathering customer insights. Keep everything practical and easy to use.

You Might Be a Good Fit If You…

• Bring strong communication and relationship-building skills across customers, executives, and internal teams.

• Are analytical and outcomes-oriented. You are comfortable owning metrics that influence pipeline, product adoption, and customer understanding.

• Use AI marketing tools in your day-to-day work and see them as essential to speed and quality.

• Have strong project management instincts and can manage complex launches, content pipelines, and cross-functional work with clarity.

• Know how to prioritize in environments with competing demands and evolving goals.

• Have a track record of shipping high-quality work across several channels at once while balancing strategic thinking with hands-on execution.

It’s a Plus If You…

• Have experience in Trust & Safety, Risk, Integrity, or AI-driven operations.

• Regularly use modern AI systems or risk ops tools.

• Have worked in a high-growth B2B SaaS startup as an early or first marketing hire.
