At SafetyKit, we use language models to tackle real-world risk and compliance challenges for some of the world's leading companies. Our technology helps teams build, refine, and enforce complex policies (think regulated goods, brand guidelines, and everything in between).
We work for payment processors and marketplaces including Upwork, Faire, Patreon, Character.ai, Substack, and Eventbrite. We built a product our users love—now they want more. We’re growing fast to meet demand and we need talented engineers to help shape the next generation of AI-powered trust and safety.
You are thoughtful, opinionated, and fast. You can own the product pipeline, from user interviews to design to pushing code that the engineering, policy, and operation teams using SafetyKit will love.
