Frontend Software Engineer

About Ventrilo.ai

Want to work on technical challenges at the intersection of LLMs, real-time AI, agents, browser extensions, and CRDTs? At Ventrilo.ai, we are building a next-generation AI experience for the browser and beyond. Our mission is to integrate AI assistance into all existing applications and workflows, enabling users to leverage their full context and receive intelligence proactively and in real-time.

As part of our crew, you'll have a seat at the table where architectural decisions are made. You'll push the boundaries of LLM-based systems, agents, browser extensions, and more. You’ll create groundbreaking solutions for problems once thought to be unsolvable. You'll collaborate closely with our PMs, engineers, and designers to ensure that our innovations address real-world issues that are worth solving.
 

You’ll work closely with our founder, Andy Chou, a Stanford Computer Science Ph.D. who previously co-founded Coverity, a successful developer tools company with a $400M exit.
 

We are backed by the following top investors: a16z, Elad Gil, Lachy Groom, Bloomberg Beta, Conviction Capital, 11.2 Capital, and Rain Capital.

Join us as we build a bridge between today’s applications and an AI-powered future.
