Full Stack Engineer (FE Focus)

Why Atrix Medical affairs teams at pharma companies are drowning in unstructured data—field notes from medical science liaisons, conference takeaways, real-world insights from post-market studies, scattered across dozens of sources. By the time these insights reach clinicians, they're stale. We're fixing that. Atrix helps medical affairs teams extract insights from messy, unstructured sources and turn them into action—so emerging findings get to clinicians faster and drugs are delivered more effectively. We're working with top-20 pharma companies and winning head-to-head against larger competitors because we actually listen to customers and build what they need.
