About the Role Join an early-stage AI workflow software company as a hands-on product engineer shaping how people work with AI teammates. You will combine product discovery, UX judgment, and full-stack engineering to build user-facing experiences and improve the outcomes they deliver. What You'll Do • Design ways for users to delegate work to AI, guide its behavior, and review its output. • Build and ship product features end to end, from React interfaces through Python services and production deployment. • Improve onboarding and help users reach a meaningful first result quickly. • Speak with users, identify problems, prioritize solutions, and write specifications when useful. • Find points of friction in the product and improve activation, retention, and other key metrics. • Polish interaction details, including empty states, copy, layout, and edge cases. • Work closely with design and growth teammates, contributing wherever a small team needs support. What We're Looking For • Three to ten or more years of experience building and shipping software products. • Experience owning a user-facing product from discovery through launch, with real users and measurable results. • Full-stack skills, including React, Python, APIs, and deployment. • Experience building AI or agent products for real users, and using agentic AI tools or AI-assisted coding in your workflow. • Strong product judgment, user empathy, design sensibility, and a bias toward shipping. • Experience moving a metric such as activation, retention, or conversion is valued, as is early-stage startup or founder experience. • Experience with Modal for infrastructure or container orchestration is useful.
