We are looking for a Senior AI Product Engineer to join a product-focused technology team in Barcelona.
This is not a pure AI/ML role. We are looking for a strong end-to-end engineer who can understand real business problems, work directly with users, challenge requirements, simplify complexity, and turn ideas into practical products that deliver measurable impact. You will be involved across the full product lifecycle: from understanding the problem and shaping the solution, to designing, building, iterating, and taking it to production.
You will work across backend, frontend, APIs, databases, integrations, automation, and AI-enabled capabilities, using technologies such as Python, TypeScript, React, FastAPI, and LLM-based tools where they genuinely add value.
If you enjoy combining product thinking, software engineering, business interaction, and applied AI, this could be a great fit.
