About Sana 

At Sana, we’re building Learn—an AI-powered learning platform that combines the simplicity of a modern LMS with intelligent features like AI tutor, automated content generation, and interactive apps. Our goal is to help enterprises make knowledge not just accessible, but actionable at scale.

We’re a product-obsessed team of engineers and designers from companies like Google, Spotify, and Databricks, united by a focus on technical excellence and rapid iteration. With Learn already supporting hundreds of leading enterprises, we’re just getting started—and there’s much more to build.

About the role

Ship customer-facing value quickly in small teams—owning everything from problem definition through UX, API, and instrumentation. You’ll work end-to-end to deliver features that delight users and move the needle for Sana and our customers.

In this role, you will
  • Own features from design to deploy—frontend (React/TypeScript), backend (Node/TypeScript) and database (Postgres)

  • Integrate with agent and retrieval APIs to deliver seamless product experiences

  • Instrument products, run A/B tests, and iterate quickly with design and PM

  • Make pragmatic trade-offs and thrive in ambiguous 0→1 product spaces

  • Collaborate closely with stakeholders, users and teammates to define and solve the right problems

What success looks like
  • Features ship fast, delight users, and drive measurable impact

  • End-to-end ownership is the norm—problems are solved, not handed off

  • Product instrumentation and A/B tests inform every iteration

  • You are a force multiplier for your squad, making everyone around you better

  • Ambiguity is an opportunity, not a blocker

Our tech stack

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

  • Backend: TypeScript, Kotlin, Node.js

  • Frontend: TypeScript, React, Tailwind

  • Databases: Postgres, Redis

  • Cloud infra: GCP/Kubernetes/Terraform

What We Offer
  • Help shape AI's future alongside brilliant minds from Notion, Dropbox, Slack, Databricks, Google, McKinsey, and BCG.

  • 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.

  • Work with talented teammates across 5+ countries, and collaborate with customers globally

  • Regular team gatherings and events (recently in Italy and South Africa)
