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:

• Be the driving force behind new products, taking them from concept to launch with a focus on professional-grade utility and smooth user onboarding
• Translate the latest AI research into practical, high-performance products
• Design and implement intuitive interfaces that make frontier AI capabilities accessible
• Prototype and launch new AI-driven products and experiences
• 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

• Technical leadership with the ability to execute and deliver zero-to-one results amidst ambiguity.
• You have an eye for new product experiences and opportunities and can envision how to make novel AI experiences a reality.
• 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.
• 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)
• You have a great design sense and can create intuitive user interfaces (Figma skills are a plus!)
• You're good at working with customers and translating their feedback into great product experiences
