About BSC

The Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain. It houses MareNostrum, one of the most powerful supercomputers in Europe, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC combines HPC service provision and R&D into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over 1000 staff from 60 countries.

Context And Mission

The AI Factory is expanding its portfolio of generative AI services and solutions to support researchers, public institutions, startups, SMEs, and industry partners in adopting artificial intelligence effectively and responsibly.

To accelerate the delivery of these services, we are looking for an AI Engineer – Generative AI Solutions who will transform validated AI concepts into robust, scalable, and production-ready applications. The role combines strong software engineering capabilities with expertise in large language models, retrieval systems, AI agents, and modern AI application architectures.

Working closely with AI engineers, project managers, domain experts, and platform teams, the successful candidate will design, build, deploy, and maintain generative AI solutions that deliver measurable value to end users while ensuring reliability, security, observability, and operational excellence.

The mission of this role is to bridge the gap between AI experimentation and real-world adoption by creating trustworthy AI products and reusable technical components that accelerate future AI initiatives across the AI Factory ecosystem.

This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement No 101234399 and Spain, Portugal, Romania and Türkiye. The JU receives support from the European Union’s Horizon Europe Programme. It is also co-funded by the Spanish Ministry for Digital Transformation and the Civil Service and counts with the support of the Government of Catalonia.

Design and optimize context management strategies, including embeddings, semantic retrieval, grounding, memory management, and knowledge integration.

Evaluate and improve AI system performance in terms of accuracy, reliability, latency, safety, scalability, and cost efficiency.

Integrate AI solutions with enterprise platforms, internal systems, authentication mechanisms, and external data sources.

Implement monitoring, observability, logging, tracing, guardrails, and operational controls for AI services.

Develop reusable software components, frameworks, templates, and best practices to accelerate AI solution delivery.

Collaborate with AI engineers, researchers, project managers, and business stakeholders to translate requirements into technical solutions.

Contribute to the definition of AI engineering standards, software architecture guidelines, and operational procedures.

Support deployment, testing, troubleshooting, and continuous improvement of AI services throughout their lifecycle.

Produce and maintain technical documentation for developed solutions, architectures, and operational processes.
