About the role

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.
