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.

Key Responsibilities

  • Design and build high-quality TypeScript & Python SDKs that delight our users by elegantly abstracting incidental complexity without sacrificing low level control (”make the common easy, and the uncommon possible”).
  • Develop and evolve complex SDK integrations and sensible abstractions
  • Create intuitive, well-typed APIs with excellent developer experience
  • Build reusable components and libraries to streamline development processes
  • Contribute to our open-source ecosystem and engage with our community. This is an excellent opportunity to grow your network and engage with technical leadership at the highest levels of industry, both on the user side and on the partner-side
  • Collaborate closely with the team to translate requirements into robust solutions
  • Collaborate closely with the team to translate requirements into robust solutions
  • Drive projects forward independently, working through ambiguity with self-direction
  • Optimize performance and ensure scalability of our infrastructure
  • Stay ahead of emerging trends in frontend and LLM development

Our main requirements are:

  • Track record building developer tools, SDKs, or libraries used by engineering teams
  • Deep TypeScript expertise (3+ years)
  • React and Node.js experience
  • Experience designing and maintaining clean, intuitive APIs and developer interfaces
  • Ability to own systems end-to-end and navigate ambiguity in fast-moving environments
  • Clear, concise communication skills and a collaborative approach
  • High degree of independence and technical judgment

Nice-to-have

If you don't have those skills, we will teach you

  • React infrastructure work beyond application development (state management, custom hooks)
  • Experience with LLM integration or AI product surfaces
  • Functional programming knowledge (especially Rust)
  • Functional Reactive Programming experience
  • Python experience
  • Open source contribution history
  • Experience with agent runtimes or real-time collaborative systems
  • Track record building and maintaining public APIs
