Cinder helps high-growth companies design, automate, and scale modern trust and safety operations. Backed by Accel.
About the role
You'll own the health, direction, and delivery of the Core Infra team. The team owns the systems the rest of engineering builds on, including the graph service, CI/CD, and core developer tooling. It's a small team that leans senior, and its work is a genuine competitive advantage for Cinder. In practice that means:
What they're looking for
- 8+ years building production software with at least 4 years in a startup environment, managing platform engineers directly. You've owned a team's delivery, not just your own, and you've grown ICs into stronger engineers
- Deep familiarity with high-throughput, data-intensive systems, workflow/automation engines, or AI-powered platforms in production, with experience managing full stack engineers
- A track record of driving a high-performing team: clear priorities and sufficient process to drive both velocity and quality, grounded in metrics
- Experience setting roadmaps and priorities in an ambiguous, fast-moving environment, and the judgment to decide what to deprioritize
- A real point of view on what high-performing engineering teams look like and how to measure them, with experience driving reliability, quality, or operational metrics
- You give direct, constructive feedback as a matter of course, and you deliver it in a way people can act on
More about this role
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.
Cinder’s Core Infrastructure team builds the platform and infrastructure that judges the safety of much of the user-generated content on the internet. This journey requires extreme focus and ruthless prioritization. As Cinder has grown, Core Infra has become responsible for the critical pieces that underpin workstreams...
