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.
