Since our founding in 1924, we've cut cardiovascular disease deaths in half, but there is still so much more to do. To overcome today's biggest health challenges and accelerate this progress, we need passionate individuals like you. Join our movement, be part of the progress, and help ensure a healthier future for all. You matter, and so does the impact you can make with us. The American Heart Association's Internship Program provides college students an opportunity for hands-on experience in various facets for individuals interested in gaining work experience with a non-profit, voluntary health organization.
This internship supports the Data Science team and provides hands-on experience in machine learning and artificial intelligence, with a primary focus on large language models (LLMs), generative AI, and agentic AI. The intern will build foundational knowledge of how LLMs work and apply LLMs to modeling, analytical workflows, and research use cases. Working with data scientists and cross-functional partners, the intern will help develop reproducible AI-enabled workflows and learn how to evaluate, validate, and document LLM-based solutions for clinical and biomedical research settings.
The Association offers many resources to help you maintain work-life harmonization through your changing needs and life situations. To help you be successful, you will have access to Heart U, our award-winning corporate university, as well as training and support locally and through our National Center. #TheAHALife is more than a company culture; it is our way of life. It embodies our commitment to work-life harmonization and is guided by our core values where our employees can thrive both personally and professionally. Discover why you will Be Seen. Be Heard. Be Valued at the American Heart Association by following us on LinkedIn, Instagram, Facebook, X, and at heart.jobs.
Individuals participating in the internship program are provided with an opportunity to:
Develop a practical understanding of foundational LLM and generative AI concepts, including prompting, embeddings, retrieval-augmented generation, tool use, and agentic workflows.
Gain hands-on experience applying LLMs to modeling, workflow automation, information extraction, summarization, and research-oriented use cases.
Learn structured approaches for evaluating and validating LLM outputs, workflows, and applications.
Strengthen skills in reproducible AI development, documentation, testing, and responsible use of AI.
Collaborate with multidisciplinary teams and communicate results to technical and non-technical audiences.
Explore a career pathway within a leading nonprofit health organization while contributing to meaningful healthcare and research initiatives.
Responsibilities
Tasks may include, but are not limited to:
Support the design and development of LLM-powered applications and agentic AI workflows for clinical, biomedical, and operational research use cases.
