WHAT WE'RE LOOKING FOR - Four to eight years of product engineering experience. - Hands-on experience with TypeScript, React, and Node.js, including ownership of both frontend and backend work. - A track record of shipping and owning features end to end, from defining the problem to production, without relying on a detailed spec. - Strong computer science fundamentals, typically demonstrated through a CS degree. - Experience on teams with high engineering standards and at a growth-stage startup; venture-backed experience is a plus. - Demonstrated product and interface craft, with examples of thoughtful UI work. - Experience using AI-assisted development tools such as coding assistants. - E-commerce or commerce platform experience is a plus.
