Sr. Associate Software Engineer (Healthcare Data Integration)

McKesson•Atlanta, GA

6d•$86,600 - $144,400

About The Position

McKesson is looking for a Sr Associate Software Engineer to join a team building a modern healthcare data integration platform that connects internal products with external Electronic Health Record (EHR) systems. This role focuses on developing scalable backend services that ingest, transform, and deliver patient data across systems—helping power clinical workflows and new healthcare products, with a little front-end UI work as well. You’ll work primarily in a TypeScript/Node.js ecosystem, contributing to event-driven microservices and collaborating with cross-functional teams in a Scrum/Agile environment transitioning toward SAFe (Scaled Agile). This is a hands-on, early-career opportunity ideal for engineers who want to deepen backend and data integration skills while building expertise in healthcare interoperability and modern cloud-native platforms. This position requires current, unrestricted authorization to work in the United States that is not time-limited or dependent on a future change in status. We are unable to consider or sponsor candidates on temporary work authorization, including F‑1 OPT, STEM OPT, CPT, or any status requiring employer sponsorship now or in the future.
