Senior/Staff Founding Software Engineer (TypeScript / Dev Infra)

About the Role

This is a deeply technical role at the intersection of frontend frameworks, backend frameworks, TypeScript APIs, real-time systems, and AI agent runtime protocols. You’ll help shape the developer experience, reliability, and scalability of infrastructure already used by tens of thousands of developers—and soon millions. You’ll collaborate with top teams across the AI infra ecosystem—from leading open-source frameworks, to hyperscalers, to cutting-edge product teams building AI into real applications.

You’ll primarily work on complex infrastructure upstream of our headless UI layer—the foundation that brings agents into production-grade, user-facing applications.

As a Senior or Staff Dev Infra Engineer at iForAI, you’ll be a key individual contributor helping define and build the core infrastructure behind the agent/user interaction layer—powering the next generation of AI-native apps. You’ll work across our open-source and enterprise platforms, focused on making it seamless for developers to integrate AI copilots deeply into their products.
