Communications Designer, Website & Marketing

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.

Cartesia is hiring a communications designer to own product storytelling and drive growth through visual design. You’ll lead design for our marketing website and support high‑impact marketing and sales assets.

• Build for iteration: Work closely with engineers to establish design experimentation and testing workflows to optimize website metrics.

• Support sales & exec storytelling: Create high‑impact decks, documents, and visual assets for customer and partner conversations.

• Clarify complexity: Turn complex technical ideas into clear, persuasive visuals for websites and presentations.

• Strong visual design instincts and the ability to turn complex ideas into compelling stories.

• You care less about “perfect” visuals and more about whether the work drives customer conversion, adoption, and revenue.

• Deep experience designing marketing websites; fluency in Figma and high‑fidelity prototyping.

• High ownership and initiative—comfort spotting gaps and defining your own scope.

• Experience supporting marketing, launches, and sales enablement.

• Proven ability to manage projects end‑to‑end and collaborate with senior stakeholders.

• Comfort giving and receiving direct feedback tied to business outcomes.

• Familiarity with voice AI or developer‑focused products.

🏢 We’re an in‑person team based out of San Francisco. We love being in the office, hanging out together, and learning from each other every day.

🚢 We ship fast. All of our work is novel and cutting edge, and execution speed is paramount. We have a high bar, and we don’t sacrifice quality or design along the way.

🤝 We support each other. We have an open & inclusive culture that’s focused on giving everyone the resources they need to succeed.
