About Mithrl We envision a world where novel drugs and therapies reach patients in months, not years, accelerating breakthroughs that save lives.

Read on to fully understand what this job requires in terms of skills and experience If you are a good match, make an application. 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
