    Description
    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.
    About the role:
    We're hiring a Founding Product Marketer to define how Cartesia shows up in the world: shaping our launches, driving adoption, and establishing us as the #1 platform for building voice agents. This is a great opportunity to join at the ground level and build product marketing from scratch at one of the most exciting companies in AI. You'll own how we tell our story and how we engage developers and enterprises.
    This role calls for someone who is both strategic and creative. You'll translate complex technical concepts into clear, compelling narratives while experimenting with bold ideas, organic growth tactics, and community-driven campaigns. You'll work directly with the founders, Product, and GTM teams, with the chance to grow into a leadership role as we scale.
    Your Impact:
    • Own and run product launches, ensuring customers and the broader market clearly understand new features and updates.
    • Work closely with Product and GTM teams to translate technical features into clear value propositions for both developer and enterprise customers
    • Drive initiatives to increase product adoption, including onboarding flows, in product messaging, and user education content
    • Create high quality collateral including website copy, whitepapers, sales enablement materials, case studies, blog posts, etc.
    • Develop and maintain personas, messaging frameworks, and positioning across all product lines.
    • Conduct competitive intelligence and translate insights into clear positioning and differentiated narratives.
    • Partner with Product and GTM teams and work directly with customers to cultivate feedback loops and use them to shape roadmap and messaging.
    • Ensure content is optimized for discoverability and engagement to align with growth marketing initiatives
    • Contribute to GTM efforts with sales enablement support (e.g., adapting messaging for customer conversations), while keeping the primary focus on outward-facing storytelling.
    What You Bring:
    • 7+ years of B2B product marketing experience, ideally with some exposure to technical products
    • Experience creating repeatable launch playbooks and scaling marketing programs from 0→1 in an early-stage or high-growth technology startup environment
    • Excellent copywriting and storytelling skills with the ability to make technical concepts accessible
    • Experience collaborating cross-functionally with Product, Sales, and Growth
    • Scrappy, entrepreneurial mindset; you're comfortable thriving in an unstructured, fast-moving environment, and effective at managing ambiguity and rapidly shifting priorities.
    • Data-driven: track KPIs like adoption, market share, and campaign ROI to guide strategy
    Nice to Have
    • Experience marketing developer-facing, infrastructure, or generative AI products or cultivating developer communities.
    What We Offer
    Lunch, dinner and snacks at the office
    Fully covered medical, dental, and vision insurance for employees
    401(k)
    Relocation and immigration support
    Your own personal Yoshi
    Our Culture
    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.
