At Indeep AI , we are an applied AI research laboratory working at the intersection of natural language processing, linguistics, and human cognition. Our work is grounded in a simple conviction: the tools we use to write and understand documents should make communication clearer and more trustworthy, not less. That research powers Typewiser, our document intelligence platform. It is backed by European research funding and built on peer-reviewed scientific foundations. We are at the stage where the way we present ourselves to the world is still being built. We’re looking for a versatile Full-Stack AI Engineer to join our team at Indeep Artificial Intelligence (IAI) at our office in Barcelona . Working closely with and directly supporting our CTO, you will move fluidly across the whole stack — from backend and platform engineering, to the LLM and AI pipelines at the core of our product, to the infrastructure that runs it, to the frontend that users touch.



This is a hands-on individual-contributor role for someone who is happiest when they can pick up almost any part of the system and make progress on it. You won’t own the architecture, but you will be the person who helps turn it into working, reliable software, and your judgement will carry real weight.

If you thrive in ambiguity, move fast without sacrificing quality, and can pivot when priorities shift, you’re exactly who we’re looking for. Contract Type: Permanent
Full Office-Based Work Modality: Monday to Friday from 9:00 to 18:00 at WeWork Glòries Barcelona
