Data Scientist/ML (Agentic AI)

Location: The role offers flexibility for occasional travel to the Warsaw office and potential international travel to Germany, approximately once a quarter.Start: Preferably ASAP or max one month noticeIndustry: Pharmaceuticals / Consumer HealthThe Mission: You are the 'brain' designer. Moving beyond classic ML models, you will design complex, multi-agent workflows. Your mission is to build the cognitive architecture of our Co-pilot for sales representatives - ranging from strict Text-to-SQL routing to human-like conversational interviews - ensuring compliance and continuous improvement.Who You Are & What You'll Do:Agentic Workflows: You have deep, practical experience building complex agent routing and state management using LangChain, LangGraph, or tools like n8n.Multimodal & Conversational AI: You have deployed advanced RAG systems and have experience integrating TTS/STT (Text-to-Speech/Speech-to-Text) pipelines for asynchronous 'Human-AI interview' conversational flows.Text-to-SQL & Business Logic Routing: You excel at mapping natural language to exact SQL parameters. You understand that the AI shouldn't 'guess' financial math; instead, it must flawlessly route intents to deterministic business logic/SQL views provided by our data teams.Continuous Evaluation & Guardrails: You know that standard testing fails with GenAI. You will design systemic validation pipelines (e.g., LLM-as-a-judge) to monitor hallucination rates, using tools like Langfuse to establish a continuous improvement loop.Multilingual Evaluation: You know standard English testing fails in localized markets. You will design systemic validation pipelines to evaluate RAG, intent classification, and transcription accuracy in Italian (handling medical/pharmaceutical jargon).Optimization & Fallbacks: You understand how to optimize AI processes—utilizing prompt caching, context-window management, and configuring faster fallback models when primary LLMs time out, ensuring a seamless user experience.Must Haves:Deep, practical experience with LangChain, LangGraph, or similar tools.Knowledge of integration concepts for TTS/STT systems.Strong Text-to-SQL skills for accurate data routing.Experience with validation of generative AI and RAG pipelines.Proficiency in Python, SQL, and Spark programming.Nice to Haves:Familiarity with GitHub for version control.Experience with FastAPI for application development.Awareness of data solutions like Databricks.Understanding of Azure cloud services.
