Cartesia is hiring: Founding Product Marketer in San Francisco

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.

Own growth marketing initiatives, ensuring content is optimized for discoverability and engagement, as well as managing any vendor/agency relationships Contribute to GTM efforts with sales enablement support (e.g., adapting messaging for customer conversations), while keeping the primary focus on outward-facing storytelling.

Experience working in an early-stage or high-growth technology startup environment. Proven experience driving or enabling product-led growth initiatives, including onboarding, in-product messaging, or self-serve activation. Proven track record of owning end-to-end launches and driving measurable growth. Experience creating repeatable launch playbooks and scaling marketing programs from 0→1.
