Product Engineer, Product Platform (Frontend)
About The Position
Replit is seeking a Product Engineer to focus on the frontend platform, which serves as the architectural and platform layer behind every core product surface. This role is highly leveraged and horizontal, offering exposure across the entire engineering organization. The team is small, collaborative, and values clear thinking and curiosity. The primary goal is to ensure product teams can ship quickly and reliably on the foundations built by this role. The work involves ensuring the core frontend architecture is sound, consistent, and easy to build on, that the API and data layer is reliable and ergonomic, that user-facing surfaces are fast and well-instrumented with safe testing infrastructure, and that the codebase is easy to navigate, change, and extend, even for AI coding agents. The engineer will partner with engineering, product, design, DevEx, and Design Engineering teams to plan, ship, and operate frontend foundations for high-traffic, latency-sensitive workloads.
Requirements
- Experience shipping and operating user-facing software in production.
- Designed frontend architecture that other teams build on (frameworks, state, routing, SSR/CSR, migrations).
- Built and operated an API/data layer (REST/GraphQL, error handling, caching).
- Measured and improved client performance with instrumentation and monitoring.
- Made and explained architecture tradeoffs across UX, correctness, delivery speed, and maintainability.
- Comfortable in modern web stacks (TypeScript, React, Next.js, Node.js).

Responsibilities
- Design platform APIs and shared primitives with clear contracts, documentation, and upgrade paths for adoption by other teams.
