About Sana

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.

About the role

You'll own the reliability, security, and scalability of Sana's platform while leveling up developer velocity. This is the place for engineers who thrive on moving between cloud infrastructure, deployment, and tooling to unblock everyone else. You'll work on everything from multi-tenant scale-out to developer experience, ensuring our platform is robust, secure, and a joy to build on.

In this role, you will

  • Drive reliability, security, and scalability across the platform

  • Architect and implement multi-tenant scale-out (10–100x) and observability solutions

  • Lead incident response, performance profiling, and cost control initiatives

  • Build and maintain CI/CD pipelines, test infrastructure, and environment provisioning

  • Work with engineers across the stack to remove friction and accelerate delivery

What success looks like

  • The platform scales seamlessly as usage grows 10-100x, with robust observability and incident response

  • Security and compliance are built-in, not bolted on

  • Developer velocity is tangibly higher—teams ship faster, with fewer blockers

  • CI/CD, test infra, and development environments are reliable, discoverable, and loved by engineers

  • Cost controls and performance budgets are visible and actionable

  • You are a go-to partner for infra, deployment, and tooling challenges: unblocking others and raising the bar for engineering excellence.

Our tech stack

We build on a simple modern stack optimized for both humans and AI.

  • Backend: TypeScript, Kotlin,

  • Frontend: TypeScript, React, Tailwind

  • Databases: Postgres, Redis

  • Cloud infra: GCP/Kubernetes/Terraform

What we offer

  • Competitive salary complemented with a transparent and highly competitive options program.

  • Swift professional growth in an evolving environment, supported by a culture of continuous feedback and mentorship from senior leaders.
