Play Ai
Palo Alto, CA

Play.ai (fka PlayHT, YC '23) is at the forefront of generative voice and conversational LLMs. With our speech synthesis and voice cloning capabilities, we are building state-of-the-art conversational AI models.

We are in the midst of an unprecedented shift in technology—AI is unlocking entirely new ways for humans to interact with computers, and we’re just scratching the surface of what’s possible.

As a frontend engineer at Play.ai , you won’t just be building interfaces—you’ll be designing entirely new experiences that redefine how people engage with AI. You’ll shape seamless, expressive, and intelligent interactions that blur the line between human and machine.

If you thrive on creativity, love pushing boundaries, and want to shape the next era of digital experiences, this is your moment.

What You’ll Do

  • Build, optimize, and refine AI-driven interfaces that feel intuitive, fast, and seamless

  • Work closely with designers and engineers to develop high-quality, interactive UI components

  • Use Next.js to improve performance through server-side rendering (SSR), streaming, etc.

  • Improve frontend performance by reducing render times, optimizing network requests, and implementing caching strategies

  • Contribute to and maintain the design system to ensure UI consistency and scalability

  • Stay up to date with modern frontend trends in AI interfaces, web technologies, and performance engineering

Who You Are

  • Strong frontend developer with a sharp eye for UI aesthetics, UX performance, and accessibility

  • Proficient in React, Next.js, TypeScript, and Tailwind CSS

  • Deep understanding of SSR, SSG, streaming, hydration strategies, and frontend performance tuning

  • Experienced in profiling and optimizing page load speed, render times, caching, and network requests

  • Able to translate high-fidelity Figma designs into polished, production-ready components

  • Familiar with design systems, RESTful APIs, WebSockets, and tRPC

  • Thoughtful about tradeoffs between client-side rendering, SSR, and SSG, and know when to use each

  • Passionate about building innovative, intuitive AI-driven experiences

  • Comfortable working independently in a fast-moving, iterative environment

What to Include in Your Application

  • A link to your online portfolio or GitHub showcasing relevant projects. Show off your creativity!

  • Your resume, CV, or LinkedIn profile

  • Any additional details that highlight your experience
