Job description

McKesson is an impact-driven, Fortune 10 company that touches virtually every aspect of healthcare. We are known for delivering insights, products, and services that make quality care more accessible and affordable. Here, we focus on the health, happiness, and well-being of you and those we serve - we care.

What you do at McKesson matters. We foster a culture where you can grow, make an impact, and are empowered to bring new ideas. Together, we thrive as we shape the future of health for patients, our communities, and our people. If you want to be part of tomorrow's health today, we want to hear from you.

Reporting to the VP of Research & Development, Matt Bates, the software engineer intern will own how to structure integrating OneStop, Macro Helix implementation team's spreadsheet-based approval process into Macro Helix's signature SaaS platform, 340B Architect.

Today, implementation teams and customers rely on spreadsheets, email and manual follow-up to validate configuration before go-live. That creates delays, uncertainty and administrative burden at one of the most critical stages of implementation. The proposal is a structured approval experience inside 340B Architect, where customers review, validate and formally approve configurations before activation. The result: greater transparency, less administrative effort, faster timelines, and Architect established as the system of record for the full implementation lifecycle.

• Understanding of object-oriented programming (OOP) principles
• Exposure to AI-assisted development, cloud technologies, APIs, and product-focused problem solving
• Exposure to one or more programming languages: C#, Java, Python, JavaScript/TypeScript
• Basic knowledge of data structures and algorithms
• Familiarity with database concepts and SQL

• Ability to learn quickly and apply new technologies
• Strong attention to detail
• Ability to work independently on assigned projects
