Frontend Software Engineer at Sentropy
Palo Alto, CA, US
The internet is a dangerous place. Sentropy builds technology to protect users from abusive content across the web.
From chatrooms for organizing ork raids, to forums where parents of disabled kids can turn for advice, to a new matchmaking app, online communities are the lifeblood of the internet. The more these spaces become part of our lives, the more important it is that we protect them from harmful content and abusive users. But when abuse evolves at the rate of the web, effective moderation becomes an expensive challenge that has never been solved at scale.
At Sentropy, we’re creating the future of scalable digital safety through powerful, intuitive tools built on top of advanced machine learning technologies that enable our users to detect, classify, and take action against harmful content. Our tech understands behavior in context and adapts in real-time to provide customers with cutting-edge protection. This enables platforms to focus on delivering the community experience they envisioned, instead of worrying about how to continuously defend against the unpredictable and unrelenting abuse that threatens their users.
Founded in 2018, we started with a vision of the technology that would power the next generation of safe digital communities - a future where anyone can develop relationships, connect with friends, and discover content without having to worry about the interactions that could harm them along the way. Today, Sentropy powers user safety at organizations big and small around the world. We’re a Series A company backed by a stable of top institutional investors, as well as founders and leaders of Reddit, Riot Games, Nextdoor, OpenAI, Twitch, Twitter, and a former head of government.
We're just getting started, and there’s a lot of internet left to protect. Come join us!
