Design Engineer

About CartesiaOur 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.About the RoleCartesia is hiring a Design Engineer to work on React design systems and product polish on our web surfaces.Your ImpactOwn the appearance of our web-based surfaces, with high agency to proactively fix design and performance issues.Design and implement UI features from scratch.Work on last-mile polish, making sure every pixel counts.Develop and maintain a React design system intended to multiply product engineering velocity.Build a process that enables Cartesia to proactively identify gaps & opportunities in the design of its web surfaces.
