Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. Replit is a software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit helps more people build and ship software. ABOUT THE TEAM Product Platform builds and owns the shared foundations the rest of Replit is built on: backend infrastructure, connectors, product primitives, and the frontend platform. When these foundations are solid, every other team moves faster. This role goes deep on the frontend platform: the architecture and platform layer behind every core product surface. The work is high-leverage and horizontal, and gives you exposure across the whole of engineering. We are a small, collaborative team that values curiosity and clear thinking over pedigree, and we care more about how you reason and build than the route you took to get here. If you like making other engineers faster, you will fit in here. ABOUT THE ROLE As a Product Engineer focusing on the frontend platform, you will own the frontend architecture behind core product experiences: application frameworks, the API and data layer, testing infrastructure, and client performance. The goal is simple: product teams ship quickly and reliably on what you build. The team’s work is guided by a few simple questions: - Is our core frontend architecture (frameworks, state, routing, SSR/CSR) sound, consistent, and easy to build on? - Is our API and data layer reliable and ergonomic, with clear contracts, sensible error handling, and effective caching? - Are user-facing surfaces fast and well-instrumented, with testing infrastructure that keeps them safe to change? - Is the codebase easy to navigate, change, and extend, including for AI coding agents? You’ll partner closely with engineering,
