Senior Software Engineer
About The Position
Flatiron Health is seeking a Senior Software Engineer to lead the technical direction of electronic prescribing (eRx) modernization in OncoEMR. The role includes designing and delivering upgrades to current standards, partnering with vendors for verification, and turning large, ambiguous problems into clear plans, tickets, and milestones. The engineer will help keep the team aligned on scope, risks, and timelines while balancing modernization with clinicians’ day-to-day needs. The position involves writing and reviewing code across C#, VB.NET, and React; guiding the transition from legacy WebForms and VB.NET workflows to React micro-frontends and .NET services; and working with product, design, QA, and clinical oncology experts to build solutions for prescriber and pharmacist workflows. The engineer will develop and test safety-critical prescribing workflows supporting ONC certification and DEA/EPCS requirements, mentor other engineers, and help shape team practices, including the use of AI tools. Success during the first year means leading eRx work from design through rollout, with reliable delivery and less friction for clinicians.
