Senior Software Engineer, Client Platform

Job description

Descript is on a mission to make audio and video content creation and editing fast, easy, and accessible to all. We are building a cutting-edge media editor incorporating real-time collaboration, ground-breaking UX, and cutting-edge AI. This is the future of media!

The Builder Experience (BIX) team is one of the critical platform teams at Descript. The group is responsible for the foundations that every product engineer builds on top of. We own the design system, core UI frameworks, client performance, state management patterns, continuous integration, and the libraries and tooling that keep our codebase healthy and our engineers productive. If it touches the client shell, rendering pipeline, cross-cutting frontend infrastructure, or GitHub Actions, it's in our orbit.

We're looking for a engineer who is deeply fluent in modern React, passionate about frontend platform work, and energized by making an entire engineering organization faster and more effective. You'll combine hands-on systems work—performance tuning, dependency management, design-system evolution—with a strong coaching and enablement mindset, helping product teams adopt improvements and level up their craft.

What You'll Do

• React: Own the use of React across the codebase. Use your expert knowledge of React to fix individual problems, design and ship systemic solutions, educate others, and keep pace with the ecosystem. Establish migration patterns, measure render performance gains, and guide teams through transitions.
