Lead Software Engineer - Bee AI

At Bumble, we’re on a mission to create a world where all relationships are healthy and equitable. The Bee AI team is reimagining how people meet by introducing an intelligent, AI-powered product that sits alongside Bumble Date - helping members connect in more curated, thoughtful, and human ways, while preserving the magic of matching and conversation at the core of the Bumble experience. As a Lead Software Engineer, you’ll play a pivotal role in shaping this next generation of connection. This is a highly impactful individual contributor role with broad influence across engineering, product, and data. You’ll operate as a technical leader within the Bee AI team, setting direction for how we build, evaluate, and scale AI agents - while collaborating with purpose, taking ownership, and seeing ideas through to real-world impact.
