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 Forward Deployed Engineer to advance our mission of building real-time multimodal intelligence by delivering agentic voice AI solutions directly into production for our customers.

Your Impact

• Be the driving force behind customer deployments, taking AI solutions from early concept and pilot to production launch with enterprise-grade reliability
• Translate cutting-edge AI capabilities into practical, high-performance systems tailored to real-world customer needs
• Design and implement agentic voice AI solutions that integrate seamlessly into customer workflows and infrastructure
• Prototype, iterate, and deploy AI-driven systems in close collaboration with enterprise customers
• Work closely with our customers to define success criteria and ensure they achieve meaningful outcomes on Cartesia’s platform
• You’ll have significant autonomy to shape customer solutions and directly impact how cutting-edge AI is deployed at scale across global organizations

What You Bring

• Technical leadership with the ability to execute and deliver zero-to-one solutions in ambiguous, customer-driven environments
• You have an eye for identifying customer problems and opportunities and can translate them into effective AI-powered solutions
• Strong engineering skills enable you to rapidly prototype solutions end to end and evolve them into scalable, production-ready systems
• You’re comfortable diving into new technologies and can quickly adapt your skills to our tech stack (Python on the backend, Go and TypeScript preferred)
• You communicate complex technical concepts clearly and effectively, and you’re comfortable working directly with customers
• You’re good at collaborating cross-functionally and translating customer feedback into actionable product and platform improvements

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.

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