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.
What you'll do
- Work directly with business teams and end users to understand their challenges, workflows, and real needs
- Translate business requirements into simple, effective,



and scalable digital products
- Design and build end-to-end solutions across backend, frontend, APIs, databases, and system integrations
- Develop backend services using Python and frameworks such as FastAPI, Django, or Flask
- Design and integrate REST APIs and connect solutions with corporate systems and internal platforms
- Automate business processes and repetitive workflows
- Apply Generative AI where it creates real value, including LLMs, RAG, embeddings, semantic search, and AI agents
- Work iteratively with users, validating assumptions and continuously improving the product based on feedback
- Take ownership of solutions from initial discovery through development, deployment, and production support
- Make pragmatic technical decisions, balancing speed, simplicity, scalability, and maintainability
- Identify when a simple solution is more effective than a complex architecture
- Collaborate
