Product Engineer, Product Platform (Frontend)

Compensation

The compensation for this role ranges from $200K to $300K, with equity offered.

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.

About the Team

The Product Platform team builds and owns the shared foundations that the rest of Replit is built on, including backend infrastructure, connectors, product primitives, and the frontend platform. This role focuses on the frontend platform, which is the architecture and platform layer behind every core product surface.

About The Role

As a Product Engineer focusing on the frontend platform, you will own the frontend architecture behind core product experiences, including application frameworks, the API and data layer, testing infrastructure, and client performance. The goal is to enable product teams to ship quickly and reliably on what you build.

The team’s work is guided by a few simple questions:

• Is our core frontend architecture 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 teams, as well as work with the DevEx team on build tooling and CI/CD, and the Design Engineering team on the design system.

What you’ll do

• Design platform APIs and shared primitives 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 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).
