We give our best effort to our work, and we put people first. We're looking for people who are determined to make life better for people around the world.

Lilly is looking for a Data Scientist to join the technology team in Indianapolis, IN supporting Global Regulatory Affairs (GRA), Global Scientific Communications (GSC), and Global Statistical Sciences (GSS). You will apply data science, machine learning, and AI techniques to solve real business problems - from building agents to automate manual regulatory workflows and optimizing clinical trial processes to building predictive models that drive smarter decisions across the portfolio. This role sits at the intersection of data, domain expertise, and engineering. You won't just build models in notebooks - you'll partner with business stakeholders to understand the problem and with leadership to quantify the impact of your work.

What You'll Be Doing

As a Data Scientist, you will work across the portfolio to identify opportunities where data science and AI can create measurable business value. You'll analyze complex datasets - regulatory documents, clinical trial data, submission timelines, operational metrics - to uncover patterns, build predictive models, and develop AI-powered solutions. You'll design and evaluate machine learning models, build NLP and generative AI applications for regulatory and scientific content, and collaborate closely with full stack engineers to move your work from prototype to production. You operate in a regulated, GxP environment where data integrity, reproducibility, and validation are not optional.

How You'll Succeed

• Partnering with business stakeholders across GRA, GSC, and GSS to understand their workflows, identify high-impact problems, and frame them as data science opportunities - translating business questions into analytical approaches.

• Developing and deploying machine learning models - classification, regression, clustering, time-series forecasting - to solve problems such as submission timeline prediction, document classification, regulatory risk scoring, and resource optimization.

• Building and evaluating NLP and generative AI solutions - leveraging LLMs, RAG architectures, text extraction, entity recognition, and document summarization to automate regulatory authoring, scientific literature analysis, and content generation workflows.

• Designing and executing experiments to evaluate model performance - using rigorous statistical methods, A/B testing, and evaluation frameworks (including RAGAS for RAG systems) to ensure solutions meet quality and accuracy thresholds before deployment.

• Designing and building AI agents and agentic workflows - creating multi-step, tool-using systems that can autonomously execute complex tasks such as regulatory document drafting, data extraction and transformation, and cross-system orchestration - moving beyond single-prompt interactions to production-grade agent architectures that operate reliably in a validated environment.

• Collaborating with full stack engineers and platform teams to productionize models - building APIs, integrating into existing applications, deploying on AWS infrastructure (Lambda, EKS, SageMaker, Databricks), and monitoring model performance in production.

• Communicating findings and recommendations to both technical and non-technical audiences - using data visualization, storytelling, and clear business-impact framing to ensure your work drives actual decisions.

• Staying current with emerging techniques in machine learning, generative AI, and data science - evaluating new tools, frameworks, and approaches for applicability to the GRA/GSC/GSS portfolio and sharing knowledge with the broader team.

Your Basic Qualifications:

• Bachelor's degree in Data Science, Statistics, Computer Science, Mathematics, or a related quantitative field

• 1 years of data science experience in Python, R and core data science libraries in a professional, academic, or internship setting

• Qualified applicants must be authorized to work in the United States on a full-time basis. Lilly will not provide support for or sponsor work authorization now or in the future for this role, including but not limited to F-1 CPT, F-1 OPT, F-1 STEM OPT, J-1, H-1B, TN, O-1, E-3, H-1B1, or L-1.

Additional Skills & Preferences

• Experience with machine learning frameworks and model deployment patterns

• Academic Background in Data Science

• Hands-on experience with NLP techniques and/or generative AI - LLM APIs (OpenAI, Anthropic), RAG architectures, vector databases, prompt engineering

• Familiarity with cloud data platforms - AWS (SageMaker, Lambda, S3), Databricks, or similar

• Knowledge of statistical methods - hypothesis testing, experimental design, Bayesian methods, regression analysis

• Experience with SAS programming

• Strong communication skills - ability to present technical findings to non-technical audiences and translate business questions into analytical frameworks

• Collaborative mindset and experience working with cross-functional teams including engineers, product owners, and business partners

Additional Information:

• Will work a hybrid schedule in Indianapolis, IN
• Remote employees will not be considered
• Lilly will not provide support for or sponsor work authorization now or in the future for this role
