    hybrid Salary not disclosed

    Agent Product Manager New York | Hybrid | Remote ABOUT CINDER Cinder provides a cutting-edge platform to protect the internet. We safeguard the interaction layer - the front end of products that users engage with, and sometimes abuse. Our AI agents, integrated workflows, and deep operational expertise help companies maintain integrity in real time, even as they scale quickly. 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 people who set ego aside, aggressively solve customer problems, and get better every day. We're building enterprise-grade infrastructure for trust, safety, and risk - and we expect everyone here to operate with ownership. THE ROLE Cinder is hiring an Agent Product Manager to help design, deploy, and scale AI-powered systems for some of our most important customers. This is a hands-on, forward-deployed product role. You'll work directly with enterprise customers to understand their workflows, risks, and goals, then use Cinder's platform to build and iterate on AI-driven solutions that operate in high-stakes, real-world environments. You'll move fluidly between product thinking and execution - shaping solutions alongside customers, partnering closely with Engineering and Design, and feeding real-world insight back into Cinder's core product roadmap. This role is ideal for someone who enjoys ambiguous problems, likes being close to customers, and wants real ownership early. You won't just define what gets built - you'll help make

  • AI Engineer

    hybrid Salary not disclosed

    AI Engineer New York | Hybrid | Remote 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. Cinder is seeking an AI/ML engineer to architect and deploy production AI systems at scale. You'll contribute to the strategic vision for machine learning and AI at Cinder, collaborating with data and software engineers to build world-class AI capabilities that directly impact our product and business outcomes. We're looking for an engineer first - someone who builds, ships, and maintains production systems rather than writing papers. If you've taken ML models from experimentation to production at scale, navigated the messy realities of real-world data, and understand that robust infrastructure matters as much as model performance, we want to talk. WHAT YOU'LL DO: - Own the complete lifecycle of large language model implementation: from data preparation and fine-tuning through rigorous evaluation and production deployment. - Develop automated evaluation frameworks

  • Software Engineer - Full Stack

    New York

    unspecified Salary not disclosed

    Software Engineer - Full Stack New York ABOUT CINDER Cinder builds the operating system for Trust & Safety. When a platform needs to write moderation policies, route content to reviewers, run AI agents against abuse, file NCMEC reports, or measure how their safety programs are performing - they use Cinder. Our customers are some of the largest internet platforms in the world, and the decisions made in our software directly determine what stays up, what comes down, and how users are treated. We're a small engineering team building category-defining software. That means the work you ship goes live to enterprise customers within weeks, not quarters - and you'll hear directly from the people using what you built. WHY THIS ROLE This is a rare opportunity early in your career: you'd join a small team building infrastructure that protects some of the largest online communities in the world. The problems are real and urgent - state-sponsored disinformation, CSAM reporting, coordinated abuse campaigns. The software you build will be used daily by reviewers, investigators, and T&S leads making high-stakes decisions. You'll ship fast, work directly with the people who use what you build, and learn from senior engineers who are deeply invested in your growth. You'll come out of this role with skills - product instinct, AI-native development, end-to-end ownership - that most engineers don't develop until much later. WHAT YOU'D ACTUALLY WORK ON Unlike a lot of early-career roles, this one gives you real ownership from day one. Here's what's on
