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 Matters

This 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.

What You’ll Do

Build core features across Mithrl’s platform, from backend services to web interfaces Work closely with our AI scientists, biologists, and product team to implement and iterate on user-facing tools Own projects end-to-end: architect, implement, test, deploy, and monitor Improve performance and stability across our infrastructure Collaborate on system design decisions as we scale across new data types, users, and geographies Contribute to internal tools that help our AI scientists and biology team ship faster Help define and shape engineering culture as we grow the team

What We’re Looking For

5+ years of experience as a software engineer, ideally at a startup or in a fast-paced product environment Strong experience with Python and Django for backend development Fluency in React for building modern, performant web applications Experience with cloud infrastructure (we use GCP, Docker, and Kubernetes) Pragmatic about trade-offs and good at balancing speed and technical debt Able to own systems and debug across layers Bias toward action, clean interfaces, and shipping fast **Curiosity, persistence, and a drive to understand how things work **High energy, strong work ethic, and a track record of getting things done **Discipline Wins: At Mithrl, the social currency is hard work and consistency. The problems we’re solving are complex and take time to bear fruit. We value teammates who show up every day, work with focus, and bring long-term discipline to their craft Bonus: experience in life sciences, data-heavy products, or working with LLMs/AI systems

What You’ll Love

Ownership: Architect and build the backbone of a category-defining AI platform Impact: Your code will accelerate real scientific discoveries and drug development Team: Join a tight-knit, talent-dense team of engineers, scientists, and builders Culture: We value consistency, clarity, and hard work. We solve hard problems through focused daily execution Speed: We ship fast (3X/week) and improve continuously based on real user feedback Location: Beautiful SF office with a high-energy, in-person culture Benefits: Comprehensive PPO health coverage through Anthem (medical, dental, and vision) + 401(k) with top-tier plans
