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.

- A small, senior team with roots at Google, a16z, Plaid, and Kickstarter. Seed stage, onsite in NYC.
- Everyone here has built and scaled products.
The role
- You'll be a core backend engineer building the services and infrastructure that power our AI platform.
- You'll design and implement scalable APIs, optimize database performance, build distributed task processing systems, and ensure our platform can handle the demands of enterprise pharma customers.
