About Mithrl

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

Mithrl is building the worlds first commercially available AI Co-Scientista 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 breakthroughsfrom 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. Were not just shipping another SaaS dashboardwere building a new kind of intelligence engine that helps scientists think and discover faster.

As a senior software engineer at Mithrl youll 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 insightsyoull 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 youll fit right in.

What Youll Do

• Build core features across Mithrls 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 Were 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 were 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 Youll 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
