Within its Architecture practice the team defines the technology strategy and cloud-native platforms behind its clients most ambitious transformation programmes. They are now growing their capability in Generative AI and agent-based solutions and are looking for a Software Architect to lead this area.

As a Software Architect specialised in GenAI and Agentic solutions your mission will be to design secure scalable and well-governed AI solutions for enterprise environments connecting systems data APIs cloud platforms and business needs.

The focus is not on years with one specific tool. What matters is a strong architecture foundation and the ability to apply it to new AI patterns taking solutions beyond the proof of concept and into real production.

You will work hand in hand with development data cloud cybersecurity and business teams acting as the technical reference in architecture discussions.

• Designing reference architectures for GenAI and agent-based solutions defining how models data APIs tools and business processes fit together

• Assessing use cases and recommending the right pattern for each one: knowledge assistants workflow automation tool-using agents multi-agent systems or AI embedded in existing products

• Defining how agents securely access corporate data and systems: permissions access control secrets management traceability and action boundaries

• Designing knowledge retrieval components (RAG vector indexes context management and data quality) that deliver relevant and verifiable answers

• Setting up evaluation and observability frameworks for AI solutions: output quality flow behaviour cost latency incidents and level of human intervention

• Integrating AI capabilities with backend architectures APIs transactional systems and cloud platforms making sure solutions are operable and maintainable in production

• Creating reusable patterns standards and technical guidelines to scale the responsible adoption of GenAI across projects and industries

• Leading architecture conversations with technical and business stakeholders identifying risks dependencies and alternatives to turn vision into a viable implementation

Essential Experience:

• 6 years in software architecture technical design or the evolution of complex enterprise solutions

• Proven experience defining distributed architectures: microservices APIs event-driven and asynchronous integration containers or cloud services

• Ability to translate business and user needs into architecture decisions technical patterns and realistic roadmaps

• Solid grasp of core architecture principles: scalability resilience security observability performance and governance

• Backend background ideally with Java Spring Boot and/or Python plus API and integration design

• Recent hands-on experience (ideally 12 years) with Generative AI LLMs RAG embeddings vector databases or intelligent automation

• Practical knowledge of agentic patterns: orchestration context management tool use decision flows API integration and human-in-the-loop

• Experience with cloud platforms (AWS Azure or GCP) and automation / Infrastructure as Code practices

• Ability to technically guide development teams and work across data cloud security and business profiles

• Based in Spain and available for a hybrid model (Bilbao preferred)

• Familiarity with GenAI / Agentic frameworks and platforms such as LangChain LangGraph Semantic Kernel CrewAI AutoGen Azure AI Foundry Amazon Bedrock or Vertex AI (no need to master them all)

• English level B2/C1 for international documentation and teams

• Join an elite team working where strategy meets technology

• Permanent contract with annual salary and career reviews

• Funded cloud certifications (AWS Azure GCP) and other technologies

• Free access to a comprehensive internal learning platform: technical methodology languages and soft skills

• Hybrid work and flexible hours

• Intensive working day on Fridays and during summer

• Corporate benefits: flexible compensation health insurance life and accident insurance and more

• Volunteering and social impact programmes

• An award-winning inclusive work culture that values diversity and teamwork
