The Position

Data Scientist

Roche Digital Technology (RDT) is where innovation meets purpose. As a global team at the heart of Roche, we are a community of business-minded technologists committed to help shape tomorrow’s digital future of healthcare. Our mission is to power Roche through cutting-edge digital technologies, harnessing the potential of artificial intelligence, data, and scalable tech innovations. Driven by purpose and passion, we’re building a future where digital is a core strength across all of Roche, enabling smarter ways of working, unlocking human potential, and driving breakthroughs that truly matter for millions of patients around the world. You'll work alongside curious, ambitious technologists who value ownership, rigour, and fast, visible impact over process for its own sake. Rather than settling into one fixed lane, you'll move with the work as priorities shift, growing your expertise across a genuinely wide range of problems. If you want your day-to-day work to reach millions of patients and to help shape what a still-emerging technology looks like in practice, this is a rare moment to join at the ground floor. At Roche, we offer a hybrid work model that combines flexibility with in-person collaboration. For now, we require our employees to be in our Warsaw or Poznań office on average two days per week. The specific office days may vary depending on business needs, such as workshops, conferences, town halls, team meetings, and other collaborative events.

The opportunity

Roche's AI Function builds the platforms, tools, and data science muscle that let teams across Roche turn AI, GenAI, and agentic ideas into real products, fast. We make it safe, simple, and scalable to build with LLMs, enterprise data, and orchestration, so experimentation stops staying experimental and starts driving real business value. And now we're pushing further into agentic AI: systems that reason, plan, and act on their own, under human oversight. Join us and help define how Roche builds, evaluates, and governs that next generation of AI at enterprise scale.

Who you are :

• Hands‑on expertise in data science and software engineering. Python, LLMs, RAG pipelines, agentic workflows. Equally comfortable writing production code, designing system architecture, or setting integration standards
• Evaluate and fine‑tune pre‑trained models for domain use. Design RAG and search/synthesis architectures. Build evaluation harnesses and statistically evaluate outputs for safety, reliability, and consistency
• Strong NLP foundations: preprocessing, language modelling, sentiment analysis, NER
• A solid core in statistics, model evaluation, feature engineering and standard algorithms
• Real depth on vector embeddings, search theory, and vector database selection and architecture, along with prompt and context engineering

Strategic and operational range

• Comfortable moving from strategic roadmap planning to solving ad‑hoc technical problems on the ground. Skilled at bridging non‑technical stakeholders and technical implementation
• Comfortable building MLOps/LLMOps pipelines for continuous deployment and monitoring, including observability for LLM systems (tracing, tokens, latency, cost telemetry and drift and hallucination monitoring).
• Comfortable forecasting and optimising infrastructure and API costs, and managing platform vendor relationships to keep tools interoperable, secure, and future‑proof

Communication

• Strong written and verbal English, with the ability to explain technical trade‑offs to technical and non‑technical audiences alike
• A learning posture that keeps pace with a fast‑changing field, with enthusiasm for knowledge‑sharing.

Preferred/nice to have

• Hands‑on experience deploying enterprise AI solutions on AWS or Azure (GCP exposure a plus)
• Model risk management, fairness and bias mitigation, transparency, explainability, and data privacy
• Pharma, healthcare, or financial services, including GxP compliance and handling sensitive information, plus awareness of emerging compliance standards for GenAI and foundation models
