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
Cartesia is hiring an AI-native Software Engineer, AI & Developer Experience to optimize developer experience and maximize ship velocity for Cartesia engineers by building tooling at the frontier of AI coding. You will also build a playbook to enable engineers and non-engineers alike to rapidly ship consistent, maintainable internal tools unassisted.
Your Impact
Build workflows that enable Cartesia to go from problem to solution with minimal human intervention.
Stay updated with the latest developments in AI-assisted development and advocate for AI-assisted development at Cartesia.
Build automated end-to-end dev & evaluation harnesses that enable coding agents to iterate on solutions and self-correct.
Build a playbook that the Cartesia team can follow to build data-connected, IAM-aware internal tooling for both human-in-the-loop and automated workflows.
What You Bring
2+ years of experience leading software engineering teams.
Strong software engineering fundamentals with a focus on writing maintainable code.
Expert in TypeScript, Python, or Go.
Deep curiosity about the state of agentic coding tools and how to optimize agent-assisted workflows.
Constantly updated on advancements in AI-assisted development and eager to validate them in a real-world setting.
Strong writing skills that help you craft detailed, nuanced agent instructions and communicate internally and externally about your learnings.
Experience collaborating with non-technical teams to build internal tools.
Nice-to-Haves
Active online presence on X/Twitter, LinkedIn, or your own blog so you can share our learnings with the world.
