About The Position

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. From crafting thoughtful front-end UX to building robust backend systems, you’ll help bridge our AI core with real-world customer pain points, working on problems that genuinely move the needle in patient care. We’re building a modular, agentic platform that connects to customer-approved data sources, transforms messy, unstructured data using advanced AI, and delivers structured, actionable insights that drive decisions in regulated environments. You’ll see your work used daily by medical, clinical, and commercial teams making high-stakes decisions. You’ll tackle rich engineering challenges across: Performance — We’re processing large data sets at once Security & Privacy — Customers trust us with sensitive data Explainability — AI outputs must be verifiable and traceable Composable UI/UX — Interfaces need to adapt to varied use cases, from chat to dashboards to spreadsheets You’ll work closely with our Engineering Team and CEO , and collaborate as a peer to product, design, and GTM leadership. As one of our earliest Full Stack Engineers , you’ll help define technical architecture, influence product strategy, and set the tone for future engineering hires. 💡 This is an hybrid role based in NYC (ability to be in office is required) , with flexibility for remote work on some days as needed.
