Careers.
Working here.

A small, senior team in Barcelona that designs and ships AI systems and stays around to run them. We are not hiring for a specific role right now, but we read every application we receive.

WHAT THE WORK IS
01

Production, not demos

Systems that have to survive a client's security review, an evaluation set and a year of real traffic. Notebooks are where work starts, not where it ends.
02

Whole problems

Retrieval, agents, integrations, infrastructure and the conversation with the client about what should be built at all. Nobody here owns a single layer.
03

Code the client keeps

Everything is written to be handed over: documented decisions, tests, repositories in the client's name. Craft is visible because it is inspected.
WHAT WE LOOK FOR
  • Evidence of shipping. Something real that you built or substantially built, that people used, with the parts you did not build named. A link beats a list of technologies.
  • Judgement about models. You have measured a system against a test set, been surprised by the result, and changed the design because of it.
  • Plain writing. Most of the job is explaining a technical decision to someone who has to approve it.
  • Comfort with saying no. A meaningful share of our enquiries resolve to “you do not need AI for this”. You should be able to say so.

We work mostly from Barcelona and remotely across European time zones. We consider applications from anyone eligible to work in Spain or to contract from within the EU, and we assess them on the work, not on background.

Sonora

Cognitive AI Ltd · 2026

A free sound-wellness app, described by its publisher as AI sound therapy that reads a short vocal sample at the start of a session and generates a soundscape for that moment. We designed and built the website and its backend, produced assets for the iOS and Android apps, and supported the application prototype.
