About Inworld

At Inworld, we believe the processes of building, scaling, and evolving applications are monsters that consume value before it can reach users. Our mission is to solve evolution and transform static software into AI systems that autonomously evolve to better serve their users. We are building an intelligent runtime to conquer these monsters and make this vision a reality.

We are backed by investors such as Intel Capital, Microsoft’s M12 fund, Lightspeed Venture Partners, Section 32, BITKRAFT Ventures, Kleiner Perkins, Founders Fund, and First Spark Ventures. Our technology is used by industry leaders like NVIDIA, Epic Games and Microsoft Xbox. Inworld has been recognized by CB Insights as one of the 100 most promising AI companies globally and has been named one of LinkedIn's Top 10 Startups in the USA.

About the role

You would join the team that builds and runs Inworld’s cloud-based services. For example, we recently launched TTS API v1, new TTS models, and a zero-shot voice cloning service. This project was a deep collaboration with the ML Speech team. We’re very proud of this work; you can read more about it (and hear examples!) at inworld.ai/tts. Or better yet, sign up and explore on your own!

We’re also hard at work on multiple projects to support the upcoming “Inworld runtime” that was announced in our blog post, A Return to the User. The runtime is still in private preview, so we can’t say too much right now, but it’s exciting, zero to one work. You would join one or more of these projects and immediately start contributing.

This is an IC-focused role. We are looking for someone who loves direct technical contribution.
