Boston Scientific was recognized as a Glassdoor Best Place to Work in 2026, ranking No. 15 on the Top 100 list, reflecting the culture our employees experience every day.

We are seeking an AI Data Engineer III to join our AI Engineering team and design, build and operate the data foundations that power enterprise AI products. In this hands‑on role, you will develop scalable data platforms and pipelines for retrieval‑augmented generation (RAG), enterprise search, document intelligence and knowledge‑driven applications.

The incumbent will own complex data engineering components from design through production, including unstructured content processing, search and vector indexing, large language model (LLM)–based enrichment, graph data and application‑facing APIs. You will partner with AI engineers, solution architects, software engineers, data scientists and business stakeholders to deliver secure, observable and cost‑effective solutions in a regulated enterprise environment.

At Boston Scientific, we value collaboration and synergy. This role follows a hybrid work model requiring employees to be in our local office Marlborough, MA or Arden Hills, MN at least three days per week. Boston Scientific will not offer sponsorship or take over sponsorship of an employment visa for this position at this time. Relocation assistance is not available for this position at this time.
