About the Role

We are looking for a product-centric engineer who cares deeply about user experience, moves fast, and uses AI as a core part of how they build.

This role is focused primarily on shipping new product features, while also owning production issues and fixing them quickly when they arise.

• Strong product sense and clear interest in building user-facing features

• Highly AI-native, with strong familiarity with modern AI coding tools and a habit of actively exploring new tools and workflows

• Strong ownership mindset and ability to drive work end-to-end

• Experience building side projects, experimenting with new ideas, or shipping independently outside of core job responsibilities

• Comfortable working across frontend and backend

• Able to thrive in a fast-paced startup environment

Preferred Qualifications

• Experience building mobile-first consumer products

• Experience with Next.js and Python

• Experience at an early-stage startup

• Experience at a high-growth or top VC-backed startup

• Active involvement in open source communities is a plus

• Computer Science background is a plus
