Phylo is an applied research lab building agentic intelligence to accelerate discovery for every biomedical scientist. We believe AI agents will fundamentally transform how biomedical research is done. Our fast-growing team brings together researchers and engineers across AI and biology.

About the role

We’re looking for a Product Engineer to help build and scale the core product experiences of Phylo’s AI agent platform. This is a highly versatile, full-stack role with a frontend lean, focused on turning cutting-edge agentic research into fast, reliable, and delightful products used by real scientists.

You’ll own product features end-to-end — from UI and interaction design to backend APIs, billing, authentication, and integrations — and work closely with AI researchers, scientists, and infrastructure engineers to ship production-grade systems quickly without sacrificing quality.

This role is deeply interdisciplinary. You’ll spend a lot of time listening, asking questions, and translating between scientists, product, engineering, and AI research. We are an AI-native engineering team: we use coding agents heavily, move fast, and hold a very high bar for engineering excellence.

What You’ll Work On

• Build and own full-stack product features across the Phylo platform, from user-facing UI to backend services.
• Design and implement frontend-heavy experiences for interacting with AI agents, workflows, and scientific tools.
• Own critical product surfaces such as billing, usage tracking, authentication, permissions, and account management.
• Collaborate closely with scientists, AI researchers, and engineers to translate capabilities into intuitive, production-ready product features.
• Ship quickly, iterate based on feedback, and continuously raise the bar on product quality, reliability, and performance.

• 2+ years of industry experience as a product, full-stack, or frontend-leaning software engineer.
• Strong experience building modern web applications (e.g. React, TypeScript, or similar frameworks).
• Comfort working across the stack (frontend, backend, and infrastructure) and strong communication skills, with the ability to collaborate effectively across biologists, product, engineering, and AI teams.
• Strong product instincts — you care deeply about UX, polish, and how real users experience the system.
• Ability to move fast, own features end-to-end, and operate with high autonomy.
• High standards for code quality, maintainability, and engineering excellence.

Nice to Have

• Experience building AI-powered products, agent interfaces, or developer tools.
• Familiarity with sandboxed or isolated execution environments for agents or user code.
• Experience with billing systems, metering, or enterprise SaaS features.
• Experience working in AI-native teams that use coding agents or automation extensively.
• Interest in scientific, biomedical, or research-focused products.
