About the Role:

We're looking for a Frontend Engineer who cares deeply about performance and craft to build video-centric interactive applications that delight and engage users. You have experience crafting fluid, multi-state, asynchronous experiences with thoughtful microinteractions and animations, and you’re comfortable translating Figma designs and prototypes into production-ready applications with rich behaviors.

Interviewing in person in San Francisco will be required.

In this role, you will:

  • Building performant, polished interfaces that allow users to interact with video

  • Craft fluid, multi-state, asynchronous experiences.

  • Translate Figma designs/prototypes into production-ready UIs with rich behaviors

  • Ensuring every interaction - from micro-animations to keyboard shortcuts - feels immediate and intentional

You may be a good fit if you have:

  • 3-5 years of experience building production React applications

  • Deep expertise in React performance optimization, render cycle management, and complex state handling

  • Track record of building smooth, responsive interfaces with real-time updates and complex interactions

  • Experience with video players, timeline interfaces, or creative tools

  • Obsessive attention to response times, polish, and the details that make products feel professional

  • Keen eye for design

Preferred Qualifications:

  • Experience with AI-powered products or creative/editing tools

  • Familiarity with video workflows (HLS, timeline-based editing, EDL/FCPXML)

  • Background in building collaborative features (real-time sync, permissions, commenting)

  • Experience optimizing large data sets in the browser (thousands of video clips)

Even if there are a few checkboxes that aren’t ticked through your prior experience, we still encourage you to apply! If you are a 0-1 achiever, a ferocious learner, and a kind and fun team player who motivates others, you will find a home at TwelveLabs.
