The Position
2027 Spring Intern - Data Science & Machine Learning
Department Summary
At Genentech, we are leveraging cutting-edge Artificial Intelligence to transform medical information delivery, commercial and clinical workflows, and patient impact. We are seeking a highly motivated Spring Intern – Agentic AI Discovery & Prototyping to join our Data Science & Machine Learning team.
In this role, you will work at the intersection of Generative AI, software prototyping, and system evaluation. You will research, rapidly prototype, and benchmark next-generation Agentic AI systems, ranging from specialized question-answering agents to multi-agent evaluation frameworks used across Generative AI initiatives. Because our work ultimately serves patients and healthcare professionals, a core pillar of your efforts will involve ensuring our agentic systems are safe, reliable, compliant, and aligned with rigorous healthcare standards.
This position is based in South San Francisco, CA, On-Site.
The Opportunity
Build, test, and refine functional prototypes for AI agent workflows tailored for interactive question-answering, search, and workflow automation.
Design and implement a general-purpose evaluation framework to benchmark LLM outputs, agent reliability, tool calling, and reasoning accuracy across projects.
Explore and implement guardrails to ensure AI agent outputs are safe, hallucination-resistant, compliant with regulatory standards, and aligned with strict patient safety and privacy guidelines.
Develop clean, maintainable Python code to integrate LLMs with internal APIs, search tools, and structured data sources.
Collaborate cross-functionally with engineers, data scientists, and domain stakeholders to gather requirements, iterate on feedback, and showcase prototype capabilities.
Share your project findings, system architectures, and evaluation metrics to the broader team at the end of your internship.
Program Highlights
Intensive 12-weeks, full-time (40 hours per week) paid internship with possibility to extend to 6 months or a year.
Program start dates are in January (Spring).
A stipend, based on location, will be provided to help alleviate costs associated with the internship.
