Software Engineer, Product Infrastructure (TypeScript DevEx)
Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide and over 500,000 business users, Replit is democratizing software development by removing traditional barriers to application creation.
About this role
Accelerate engineering velocity and reduce friction in the Replit development experience by stewarding our TypeScript monorepo, tooling, and developer workflows. You will be directly impacting all our engineers working in this monorepo daily. By focusing on developer experience, you will act as a force multiplier across all product development teams, enabling faster feature delivery, happier developers, and reduced operational overhead.
The role combines the technical depth needed to navigate a complex monorepo with the product mindset to understand how infrastructure decisions impact developer productivity and ultimately customer value delivery.
Additionally, you will be a key decision maker in the Agent’s default stack (Vite + React + Express) and will help the AI team with strategies to improve the Agent’s output and stack.
This is a first hire in this area, so you will automatically be in a position of leadership and have an accelerated career path as the team undoubtedly grows.
You will:
Maintain and evolve a complex monorepo structure spanning frontend, backend, npm packages, and tooling.
Own the build pipelines and optimize them to minimize build times and improve developer iteration speed.
Improve and oversee code generation such as GraphQL and Protocol Buffers to ensure our code is type safe.
Set the standards for code quality using automation tools such as TypeScript, Prettier and Eslint, building custom rules and plugins to enforce Replit-specific requirements.
Streamline local development setup and onboarding experience.
Work with platform teams to improve deployment processes, infrastructure integrations, and external tooling.
Keep things fresh and modern in our codebase by adopting and leading migrations to better and faster tools.
Help manage dependencies both internal (public and private) and external, including being the face of the company when interfacing with open-source libraries such as when it comes to sponsorships.
Required skills and experience:
Expertise in TypeScript build systems such as Vite, TypeScript, webpack, and so on.
Proficiency with ESLint, Prettier, testing frameworks, and code generation tools.
Experience managing monorepos or large-scale codebases
