About Cartesia

Our mission is to build the next generation of AI: ubiquitous, interactive intelligence that runs wherever you are. Today, not even the best models can continuously process and reason over a year-long stream of audio, video and text—1B text tokens, 10B audio tokens and 1T video tokens—let alone do this on-device.

We're pioneering the model architectures that will make this possible. Our founding team met as PhDs at the Stanford AI Lab, where we invented State Space Models or SSMs, a new primitive for training efficient, large-scale foundation models. Our team combines deep expertise in model innovation and systems engineering paired with a design-minded product engineering team to build and ship cutting edge models and experiences.

We're funded by leading investors at Index Ventures and Lightspeed Venture Partners, along with Factory, Conviction, A Star, General Catalyst, SV Angel, Databricks and others. We're fortunate to have the support of many amazing advisors, and 90+ angels across many industries, including the world's foremost experts in AI.

The role

We're hiring a Product Engineer to advance our mission of building real-time multimodal intelligence. In this role, you'll:

1. Be the driving force behind new products, taking them from concept to launch with a focus on professional-grade utility and smooth user onboarding

2. Translate the latest AI research into practical, high-performance products

3. Design and implement intuitive interfaces that make frontier AI capabilities accessible

4. Prototype and launch new AI-driven products and experiences

5. Work closely with our customers to make sure they're successful

You'll have significant autonomy to shape our products and directly impact how cutting-edge AI is applied across various devices and applications.

What we're looking for

1. Technical leadership with the ability to execute and deliver zero-to-one results amidst ambiguity.

2. You have an eye for new product experiences and opportunities and can envision how to make novel AI experiences a reality.

3. Strong full-stack engineering skills enable you to rapidly prototype and iterate on ideas from end to end, and later, build them for scale and to last.

4. You're comfortable diving into new technologies and can quickly adapt your skills to our tech stack (Go and Python on the backend, Next.js for the frontend)

5. You have a great design sense and can create intuitive user interfaces (Figma skills are a plus!)

6. You're good at working with customers and translating their feedback into great product experiences
