Job Description:

Breakthrough medicines all start the same way: years of research, mountains of data, and countless decisions made by medical teams within the world's premier biopharma labs. These decisions then determine which treatments make it to market, how doctors learn about them, and ultimately which patients get access to life-saving care and when. We're at an inflection point. AI-powered drug discovery, precision medicine, and an explosion of real-world evidence have accelerated what's possible, but the teams translating science into patient access are drowning in data they can't use. The tools haven't kept up with the stakes. Atrix builds purpose-built AI for life sciences, designed for the accuracy and rigor biopharma requires. We're live with top-10 pharmaceutical companies, scaling fast, and focused on one thing: helping the right treatments reach the right patients, sooner The Role Description You’ll be a core builder of the Atrix AI-native platform, designing and shipping features that turn complex healthcare and AI workflows into intuitive, elegant interfaces, trusted by scientific, medical, and commercial teams across top pharma companies.
