This multidisciplinary group works collaboratively with our discovery and manufacturing colleagues.

We are seeking an AI Data Engineer to build the data ingestion infrastructure and a unified data model that underpins the modernized CMC Data Backbone. This is a hands-on engineering role with design influence - you will write production-quality pipelines, define CMC data schemas, and work directly with scientists and digital architects to ensure data from internal LIMS/ELN systems and external CDMO partners flows reliably into a single data backbone.
You will work with a team of engineers and data scientists. You will have the autonomy to own your components end-to-end. If you want hands-on experience at the intersection of pharmaceutical science and modern agentic AI data engineering - agentic pipelines, document AI, GxP-compliant data infrastructure - this is the role to build that foundation.

Key Responsibilities:

• Implement individual agent components (e.g., document extraction agent, schema mapping agent, validation agent) within the established orchestration framework (LangGraph, LlamaIndex, or equivalent)

• Write tool-calling logic, handle failure modes, and ensure each agent component is testable and observable with instrumented logging of inputs, outputs, and intermediate decisions

• Iterate on agent behavior based on real data performance; work with the senior engineer to identify and resolve failure patterns

• Participate in validation and qualification activities for AI-assisted workflows, supporting documentation that demonstrates computational tools reflect scientific intent

• Build review queues and flagging logic that surface low-confidence or out-of-specification extractions to scientific reviewers for approval before data is loaded

• Implement routing logic that captures reviewer decisions, logs outcomes with full audit trail, and reintegrates approved data into the pipeline per 21 CFR Part 11 electronic records requirements

• Tune flagging thresholds based on feedback from scientific owners; maintain and improve HITL logic as new data sources are onboarded

• Design and build AI-assisted ingestion pipelines that extract and structure the data from unstructured CDMO/CRO data sources: PDFs (Certificates of Analysis, batch records), Excel files, and vendor portal exports

• Implement validation, reconciliation, and exception-handling logic to ensure data completeness and integrity before loading

• Build monitoring and alerting for pipeline health, data quality, and ingestion failures

• Design a data quality framework with automated checks, rejection handling, and audit trail logging.

• Develop reusable pipeline templates and schema documentation that reduce onboarding time for new CDMO partners

• MS in Computer Science, Computer Engineering, Data Engineering, or related technical field with 1-2 years of relevant experience; OR

• BS in Computer Science or Computer Engineering with 3-5 years of hands-on data engineering experience.

• Proficiency in Python and SQL; ability to write, review, and own production-quality code.

• Demonstrated experience building ETL/ELT pipelines from unstructured or semi-structured sources (PDFs, Excel, JSON, XML).

• Hands-on experience building LLM-powered applications: retrieval-augmented generation, tool-calling, multi-step orchestration, or equivalent agentic patterns.

• Hands-on experience with cloud data platforms: Azure (Data Factory, Databricks, Fabric) or AWS (S3, Glue, Lambda, Redshift).

• Solid understanding of relational data modeling, schema design, and data normalization principles.

• Familiarity with data orchestration tools (Airflow, Azure Data Factory, Prefect, or similar).

• 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 or visas 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.

• Working knowledge of 21 CFR Part 11, ALCOA+, and GxP data integrity principles, or clear demonstrated ability to apply similar audit/compliance frameworks.

• Experience integrating data from LIMS, ELN, SDMS, or CDS systems (Benchling, LabVantage, OpenLABS, or equivalent).

• Familiarity with pharmaceutical CMC data types: analytical results, batch records, stability studies, specifications.

• Experience with data mesh architecture or data product ownership models.

• Knowledge of MLOps practices and preparing data for AI/ML model training in regulated environments.

• Exposure to regulatory submission data formats (eCTD, CTD, CDISC SEND/SDTM).

• Experience with CI/CD pipelines (GitHub Actions, Azure DevOps) applied to data engineering workloads.
