Sana is an AI lab building superintelligence for work. We believe organizations can accomplish their missions faster when teams can effortlessly access knowledge, automate repetitive work, and learn anything with the help of agentic AI. As part of Workday, we are committed to building AI that augments people - not replaces them.
We bring this mission to life through two products. Sana Agents provide a seamless way to access all your company’s apps, knowledge, and data, enabling AI agents to do real work so teams can process and act on information at unprecedented scale. Sana Learn is an AI-powered learning hub that combines the simplicity of a modern learning platform with intelligent features like an AI tutor, automated content generation, and interactive apps, making knowledge not just accessible but actionable.
We’re a talent-dense, product-obsessed team of engineers and designers from companies like Google, Spotify, Apple, and Databricks, united by deep technical excellence and rapid iteration. Our tools already help over a million people learn and work better across hundreds of leading enterprises - and we’re just getting started.
You’ll own the core web stack at Sana - from our TypeScript/React frontend to the Node services, tooling, and monorepo infrastructure that power it. This is a role for engineers who love unblocking others: you’ll design and maintain the build systems, frameworks, and developer workflows that let teams ship fast, safely, and with confidence. You’ll work on everything from core web architecture and performance to CI, testing, and local development, ensuring our web platform is modern, secure, and a joy to build on.
