About Us

PlayHT is at the forefront of generative voice and conversational LLMs. With our Speech Synthesis and Voice Cloning models, we are building the SOTA conversational AI products.

We are building a platform and infrastructure for Conversational AI Voice Agents so that every business, developer, or tinkerer can easily build talking human-like AI agents and use them to serve their customers; this will unlock massive value for the world and a lot of happiness for people using these delightful agents.

We joined YC last year in the YC W23 batch. Since then, we have raised $8m in seed funding and seen significant growth in users and revenue (20x the last two years).

What Are We Looking For?

We're looking for a Senior Fullstack Product Engineer who is passionate about solving challenging problems and inventing the future of how people interact with LLMs. By joining our conversational agents team, you have the opportunity to be a founding engineer and play a pivotal role in shaping the future of Conversational AI.

Examples of what you could do:

  • Redesign core full-stack features like extending conversational voice agents to use tools and actions.
  • Create Conversational voice experiences utilizing our Voice APIs and other 3rd party LLM APIs.
  • Prototype and experiment with new ways to get users to their first magical "aha!" moment when creating voice agents.


  • Ship new features and build infrastructure using TypeScript, Nextjs, React, CSS, Firebase, and Node.js.
  • Improve the performance and user experience of existing features across the product, anywhere from signup to advanced use cases.


  • At least 5 years of professional software development experience.
  • Working experience building full stack applications with TypeScript and Nextjs.
  • Working experience building directly for users.
  • Self-directed and comfortable working autonomously.

What We Offer:

  • A pivotal role in a rapidly growing startup at the forefront of conversational AI technology.
  • The opportunity to solve challenging problems and innovate in uncharted territories.
  • A culture that values technical excellence, continuous learning, and collaboration.
  • Competitive compensation, including equity, reflecting your experience and contribution to the success of the company.
  • Flexible working hours.
  • Comprehensive benefits package, including health, dental, and vision insurance; commuter benefits; flexible PTO; and holidays.

Final offer amounts are determined by multiple factors, including but not limited to experience and skill level, and may vary from the amounts listed above.
