Sr. Full Stack Engineer

About MithrlWe envision a world where novel drugs and therapies reach patients in months, not years, accelerating breakthroughs that save lives. Mithrl is building the world's first commercially available AI Co-Scientist—a discovery engine that empowers life science teams to go from messy biological data to novel insights in minutes.
Scientists ask questions in natural language, and Mithrl answers with real analysis, novel targets, and patent-ready reports.
No coding.
No waiting.
No bioinformatics bottlenecks.
We are the fastest growing tech-bio startup in the Bay Area with over 12X YoY revenue growth.
Our platform is already being used by teams at some of the largest biotechs and big pharma across three continents to accelerate and uncover breakthroughs—from target discovery to mechanism of action.
Why This Role MattersThis is a chance to work on one of the most ambitious technical and scientific challenges of our time.
We're not just shipping another SaaS dashboard—we're building a new kind of intelligence engine that helps scientists think and discover faster.
As a senior software engineer at Mithrl, you'll work closely with our AI, product, and biology teams to build the systems that power the AI Co-Scientist.
From research question parsing and large-scale data processing to fast, intuitive interfaces for scientific insights—you'll help bring speed, clarity, and power to modern biology.
We care deeply about clean code, thoughtful abstractions, and fast execution.
If you want to build real products with real impact and learn from a dense, high-output team, you'll fit right in.
