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, product, and design. You’ll also work with our DevEx team on build tooling and CI/CD, and our Design Engineering team on the design system, to plan, ship, and operate the frontend foundations used across high-traffic, latency-sensitive workloads.
What you’ll do
Design platform APIs and shared primitives (not just components) with clear contracts, documentation, and upgrade paths that other teams adopt
Profile and instrument real user journeys, then ship the changes that move the numbers
Roll out cross-cutting changes safely with codemods, migration paths, and staged rollouts
Set technical direction in design and architecture reviews, and document the decisions and operational expectations behind them
Work directly with product teams to turn their friction into reusable platform improvements
Required skills and experience
Experience shipping and operating user-facing software in production
Designed frontend architecture 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)
If you’re excited about this role but don’t meet every requirement, we still encourage you to apply.
This is a full-time role that can be held from our Foster City, CA office. The role has an in-office requirement of Monday, Wednesday, and Friday.
