About the Role

We’re looking for a

Staff Software Engineer to join our

Funnels AI Team, the group responsible for building the next-generation AI engine that powers the entire Funnels experience — from smart funnel creation, adaptive conversion flows, automated copy/design generation, real-time optimization, and predictive analytics across our product ecosystem.This team owns the intelligence layer that helps millions of SMBs build high-converting funnels without technical expertise. The Funnels AI platform orchestrates complex workflows across data processing, LLM-powered reasoning, design generation, experimentation frameworks, and personalized content delivery. With millions of funnels and billions of visitor interactions flowing through our systems, reliability, correctness, and performance are mission-critical. As a

Staff Engineer, you will set the technical direction for our AI-driven funnel architecture, guide complex system design decisions, and mentor 10+ engineers across multiple squads working on AI Funnel/Website Builder, Blog AI Builder, Forms AI Builder and AI Agents. You’ll collaborate closely with product, infra, and design to define long-term strategy, improve engineering excellence, and deliver intuitive, generative, high-performance user experiences at scale.
