Security Engineer

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.

We are seeking a Security Engineer with a strong software engineering and DevOps background to enhance our engineering team. This role combines security, compliance, and DevSecOps to ensure our infrastructure is secure, compliant, and efficiently managed. As a key member of the Information Security group, you will maintain and enhance our established compliance programs while driving security excellence across our engineering organization. This role combines hands-on technical and deep compliance expertise to ensure continued customer trust as we scale.
