Overview

Millions of developers start their day on GitHub — and the frontend platform you build will define the quality, speed, and reliability of that experience. As a Senior Software Engineer on the React Platform team, you will design and evolve the frontend architecture, frameworks, tooling, and performance infrastructure that underpin GitHub's entire web UI — enabling engineering teams across the company to build scalable, accessible, performant, and secure React applications with confidence. You will grow your expertise across large-scale React architecture, client-side performance optimization, and platform-as-a-product thinking.

The React Platform team is part of the Core UX org in Core Productivity. We are an enablement-focused platform team — our customers are both the millions of developers who use GitHub every day and the internal engineering teams we accelerate through expert guidance, reusable patterns, and production-ready tooling. We measure our success by web performance benchmarks, developer experience scores, and how quickly product teams can go from idea to production on our platform.
