Backend Engineer, AI Noa Notes (100 remote-friendly within Spain)

Team Vision and Mission

The Noa Notes Team is building AI tools that turn doctor-patient conversations into structured clinical notes. Our mission is to make clinical note-taking so seamless and reliable that it becomes invisible: doctors speak naturally and Noa handles the rest.

With 12000 paying users and over 1.5 million consultation minutes processed weve proven the value. Now were scaling: improving summary quality expanding across devices and platforms and building a product-led engine.

Why Our Team

We have real traction and proof that what were building matters. With a team of just nine were small enough that your work will directly shape the products trajectory.

Youll tackle hard problems at the intersection of AI distributed systems and healthcare workflows with real-time audio processing multi-cloud integrations and making machine-generated summaries trustworthy enough for clinical use. 

Youll own features from ideas through impact measurement. We ship small increments to production early and often optimizing for learning over big-bang releases. Youll propose trade-offs make day-to-day calls and see the results in real user data within weeks.

Fair warning: youll wear multiple hats and context-switch often.
Thats a feature for some a bug for others.
