Software Engineer

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 text1B text tokens, 10B audio tokens and 1T video tokenslet alone do this on-device.

Were 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.

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