About the role
About Cinder
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.
Why this role
Cinder is an AI-native safety platform serving over thirty customers, including some of the largest consumer platforms in the world. Many of them serve tens or hundreds of millions of users, and the safety decisions made in our software shape what those users experience every day. That reach comes with real product surface area: a growing set of AI-native products, a mature platform that enterprise customers depend on daily, and a roadmap with more good problems than any one person can carry.
This is a chance to own several of them outright. You'll take multiple related products or surfaces from first principles through launch and adoption, with the autonomy to make the calls and the accountability for how they land. You'll report to and partner closely with our Head of Product, and you'll own meaningful product direction within your areas from day one.
What you'll work on
- Owning multiple related products or surfaces end to end, from problem framing through launch and adoption, holding a clear view of the customer, business, and product outcomes for each.
- Running discovery with customers, prospects, and the teams closest to them, turning what you learn into product direction that scales across the customer base.
- Shaping the roadmap: translating company strategy into a concrete plan, and making the real calls about where AI agents, platform investments, quality, and customer needs sit relative to each other.
- Writing the requirements and decision documents that let Design and Engineering move fast and with confidence: the what, the why, the success measures, the scope, and the edge cases.
- Partnering deeply with Design and Engineering through delivery, resolving ambiguity quickly, pressure-testing scope, reviewing work in progress, and owning final product sign-off.
- Communicating with clarity across the company, so everyone knows what's shipping, why, and what customer outcome it's meant to achieve.
What we're looking for
- 5+ years in product management, including time in a Senior or Staff-titled role owning complex products end to end, from discovery through measurable customer or business outcomes.
- Experience building B2B or enterprise SaaS with real depth: complex workflows, multiple personas, and heavy configuration. Our product is technically deep, but many of our users are domain experts rather than technical ones, so you know how to make powerful software feel simple and keep the interface approachable for technical and non-technical users alike.
- Strong customer discovery skills. You can sit with a customer, find the real problem underneath what they're asking for, and turn it into product direction that scales.
- Excellent prioritization. You can make and explain hard tradeoffs across strategic bets, customer commitments, quality, platform work, and near-term revenue.
- Technical fluency. You reason about systems, data, APIs, AI behavior, and implementation tradeoffs with engineers as a credible partner.
- Excellent writing and communication. Concise requirements and decision docs, clear updates, and the ability to align technical and non-technical stakeholders.
- A track record of shipping in fast-moving, ambiguous environments, where you create clarity instead of waiting for a finished playbook.
- Strong systems thinking. You anticipate edge cases, downstream effects, product debt, and how a decision in one surface ripples across the platform.
- High ownership and low ego. You seek evidence, invite critique, change your mind when warranted, and disagree directly and constructively when it matters.
- Experience navigating the tension between Design, Engineering, executives, GTM, and customer-facing teams, aligning competing priorities into a single product direction.
Nice to have
- Experience building AI- or ML-powered products, especially where quality, evaluation, observability, human oversight, or model behavior matter.
- Experience with workflow products, data platforms, developer tools, operations software, or other information-dense products where power users need to move fast and make changes on the fly.
- Comfort with and empathy for Trust & Safety, integrity, fraud, risk, compliance, or adjacent high-stakes use cases.
- Experience evolving a mature platform product while launching new product lines alongside it.
- Experience at an early-stage or scaling company where PMs owned broad surfaces and helped establish lightweight product practices.
- A perspective that broadens how we think about product, rather than reproducing the same background across the team.
