Your Mission:

We are seeking a skilled AI Engineer / Full-Stack Developer to join our innovative Agentic AI Center of Excellence team in Barcelona. This hybrid role will play a pivotal role in designing, developing, and deploying agent-powered process automation solutions for key processes (P2P, O2C, A2R, G2G, tax, payroll). The candidate will blend expertise in AI engineering (agent orchestration, LLM integration) with full-stack development (client portals, omnichannel interfaces) to drive efficiency, scalability, and compliance in a POC phase, with potential expansion.

Key Responsibilities:

• Develop and optimize autonomous AI agents for fiduciary workflows, leveraging embedded LLMs and multi-agent systems.
• Implement retrieval-augmented generation (RAG) using vector stores and MS Fabric / Databricks data pipelines for advanced insights.
• Design reusable modules for task execution, reasoning, and monitoring, ensuring scalability across multiple clients.
• Integrate custom tools and infrastructure to support agent-powered automation, aligning with European and international standards.
• Full-Stack Development:
• Build and maintain client-facing interfaces, including self-service portals and mobile apps, using modern frameworks.
• Develop omnichannel experiences for clients, employees, and partners, ensuring seamless onboarding and engagement.
• Collaborate on platform operating models, focusing on orchestration, governance, and compliance by design.
• Work with finance experts, supervisors, and the core operating team to embed domain expertise into AI solutions.
• Contribute to POC development, tooling, and infrastructure setup, accelerating delivery and reducing error rates.
• Support group alignment and vision by designing scalable technology that meets business outcomes and quality management goals.

Your Profile:

• Technical Skills:
• Proficiency in AI/ML frameworks (e.g., TensorFlow, PyTorch) and LLM orchestration, including LangChain, LlamaIndex, CrewAI, Hugging Face Transformers, and Azure OpenAI API for advanced agent development.
• Expertise in AI engineering with a focus on chain-of-thought reasoning, structured outputs (e.g., JSON, XML), and fine-tuning LLMs for domain-specific tasks such as fiduciary process automation.
• Experience with Databricks, vector stores (e.g., Pinecone, FAISS), and data pipeline engineering using MS Fabric for centralized data management.
• Full-stack expertise (e.g., React, Node.js, Python) with a focus on scalable web applications and integration with AI-driven workflows.
• Knowledge of cloud platforms (e.g., Azure) and DevOps practices (CI/CD, MLOps) to ensure robust deployment and monitoring.
• Advanced knowledge of vibe-coding technics and product development life cycles.
• Experience:
• 3+ years in AI engineering or full-stack development, with hybrid project experience preferred.
• Proven track record in process automation or agent-based systems.
• Soft Skills:
• Strong problem-solving and innovative mindset to drive efficiency and task execution.
• Ability to collaborate across teams, including finance experts and supervisors, for knowledge base integration.
