Profile match
Cartesia is an artificial intelligence research and technology company that builds real-time, low-latency generative voice models for interactive applications. Founded by Stanford researchers, the company utilizes State Space Models (SSMs) to power its flagship text-to-speech platform, Sonic, which enables sub-second voice synthesis, instant voice cloning, and emotional expression across dozens of languages. By providing real-time speech generation and voice agent infrastructure, Cartesia allows developers and enterprises to power conversational AI systems, virtual assistants, and customer service platforms.

About Cartesia

Our mission is to architect AI that learns from and interacts with the world like humans do.

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 an Inference Engineer to advance our mission of building real-time multimodal intelligence.

Your Impact

  • Design and build low latency, scalable, and reliable model inference and serving stack for our cutting edge foundation models using Transformers, SSMs and hybrid models.

  • Work closely with our research team and product engineers to serve our suite of products in a fast, cost-effective, and reliable manner.

  • Design and build robust inference infrastructure and monitoring for our products.

  • Have significant autonomy to shape our products and directly impact how cutting-edge AI is applied across various devices and applications.

What You Bring

Given the scale and difficulty of problems we work on, we value strong engineering skills at Cartesia.

  • Strong engineering skills, comfortable navigating complex codebases and an eye for writing clean and maintainable code.

  • Experience building large-scale distributed systems with high demands on performance, reliability, and observability.

  • Technical leadership with the ability to execute and deliver zero-to-one results amidst ambiguity.

  • Background in or experience working on inference pipelines with machine learning and generative models.

  • Experience implementing state of the art Machine Learning models and research to applied problems.

  • Preferable: experience with vLLM, SGLang, Continuous Batching or other inference frameworks.

  • Preferable: experience working in CUDA, Triton or similar

Note: Cartesia participates in E-Verify and will provide the federal government with Form I-9 information to confirm employment eligibility after hire.
