About the job
About Cartesia
At Cartesia, we are on a mission to revolutionize artificial intelligence by creating interactive, ubiquitous intelligence that operates seamlessly in any environment. Our vision includes pushing the boundaries of current AI capabilities, enabling models to continuously process and reason over vast streams of audio, video, and text data, 1 billion text tokens, 10 billion audio tokens, and 1 trillion video tokens, on-device.
Our pioneering work in model architectures originates from our founding team’s experience at the Stanford AI Lab, where we developed State Space Models (SSMs), a breakthrough approach for training large-scale, efficient foundation models. Our team is a blend of deep expertise in model innovation and systems engineering, combined with a design-focused product engineering team dedicated to launching cutting-edge models and user experiences.
Backed by top-tier investors including Index Ventures and Lightspeed Venture Partners, alongside a robust network of advisors and over 90 angel investors from various sectors, we are fortunate to collaborate with some of the leading minds in AI.
About the Role
We are excited to welcome our first Solutions Engineer, who will play a vital role in facilitating the enterprise adoption of Cartesia’s voice AI infrastructure. Our clients are developing real-time voice agents, call automation systems, and AI workflows that rely on low latency, reliability, and seamless production-grade integration.
As a Solutions Engineer, you will collaborate closely with Account Executives throughout the technical aspects of key deals, from initial discovery to proof-of-concept and technical validation. You will bridge the gap between engineering and market entry, translating customer workflows and infrastructure challenges into actionable architectural solutions.
This role demands a proactive, hands-on approach. You will write code, create demos, prototype integrations, and engage in technical discussions with engineering leaders. Rather than following an existing playbook, you'll contribute to developing one by establishing demo environments, documentation, and scalable processes as we expand.
Your contributions as a Solutions Engineer will be crucial for our growth; deals will be secured because of sound architecture, functional integration, and the trust we build with customers to power their real-time production systems.
