Senior AI Engineer We are looking for an AI Engineer / Agent Developer to design and build advanced conversational solutions that enable users to interact with complex data in a simple, reliable, and explainable way. This role focuses on developing intelligent agents that transform natural language into actionable insights, operating within a highly governed and data-driven environment. You will work closely with cross-functional teams across data, analytics, and product to deliver scalable, high-impact AI capabilities. What you will do • Build and iterate the conversational analytics agent end-to-end: query understanding, SQL generation, execution, response synthesis, explainability and citations., • Implement guardrails: scope enforcement, hallucination detection, traceability for high-stakes clinical answers., • Select an orchestration pattern proportionate to PoC evidence (linear plan-act-reflect, ReAct, or multi-agent) and document the rationale., • Model access: integrate with Apollo gateway; follow cross-region inference and model-routing conventions defined by the central platform team, • Data access: implement purpose-bound data scoping (objects, attributes, row-level) per user function; align with the data-platform team on the chosen mechanism (Snowflake RBAC, row-level security, MCP, or a combination), • Integrate the agent with central semantic assets owned by the Data Foundation team: business glossary, KPI definitions, semantic views, ontology references., • Contribute use-case-specific semantic enrichments back into the central layer., • Design for re-hookability as the OMA warehouse migrates into the Medicine Data Foundation., • Design and operate a structured evaluation harness: SQL correctness, answer faithfulness, regression on a golden-question set., • Maintain a verified-query repository for OMA clinical use cases (CDO, QM, RA domains)., • Apply statistical rigor: confidence intervals, regression gates, drift detection., • Run adversarial / red-team testing in close loop with clinical analysts., • Observability for agent traces using one chosen tool (LangSmith or equivalent): plan generation, tool calls, intermediate outputs., • Monitor latency, token cost, error rates; collaborate with platform and FinOps on cost attribution and quota policy., • IT EDP Medicine Data & Analytics What we are looking for • Strong experience with Python at production level., • Advanced SQL skills, including analytical queries and optimization, • Prompt engineering, function calling / tool use, ReAct or plan-and-execute patterns., • Demonstrable experience building text-to-SQL or conversational-analytics systems., • Working knowledge of Snowflake (data modeling, SQL, basic Cortex concepts)., • Agent-orchestration capability, either: LangGraph (for custom-build track) OR a vendor agent platform such as Snowflake Intelligence, Cortex Analyst, or comparable., • Working experience with structured evaluation frameworks (Ragas OR DeepEval) and/or observability tools (LangSmith, Weights & Biases, Arize, or equivalent)., • Working in regulated, governance-first environments: RBAC, data classification, audit trails, responsible-AI guardrails., • Advanced English Level. Nice To Have • Snowflake Cortex deep experience: Cortex Analyst, Semantic Views, Cortex Search., • Apollo / internal-LLM-gateway integration experience, or willingness to ramp quickly., • Clinical-operations domain awareness (a paired OMA clinical analyst is part of the working setup)., • Knowledge graph / ontology experience (relevant for Phase 2 when EKG integration becomes active)., • Infrastructure-as-code for Snowflake (Terraform, Schemachange, SnowCLI)., • Containerization basics (Docker, Kubernetes) for custom agent services on the build track., • Familiarity with FAIR data principles, CDISC, or DDF What We Offer • Permanent contract through Hays., • Flexible remote working model, with one day per month on-site at the office in Sant Cugat del Vallès, Barcelona., • Competitive salary package., • Work on a high‑impact internal platform used by global teams, • Join a stable, innovation‑driven pharmaceutical environment with a long‑term mindset, • Opportunity to contribute to automation and future AI initiatives in a regulated, meaningful industry 💡 If you're passionate about building impactful solutions and want to be part of a collaborative, forward-thinking team, we’d love to hear from you.
