About Cinder

Cinder provides a cutting-edge platform to protect the internet. Trust & Safety and AI safety teams at the world’s most influential companies need powerful solutions that allow them to innovate and adapt as quickly as the threats they face. Companies rely on our software to make policies, moderate, enforce, investigate, and disrupt threats like hate groups and state-sponsored disinformation campaigns.

Cinder is seeking an experienced senior software engineer for our team building an enterprise content safety platform to make the internet safer. 

We believe in the value of frequent in-person meet-ups and learning face to face, so we encourage teammates in SF/NYC/London to work together when possible, and we have at least two all-company events per year. In the US, we offer health, vision & dental benefits, and a 401(k) plan with employer matching.
