About the job
We're building an AI Agent that can think, analyze, and instantly simulate real shoppers. After decades creating top-tier consumer insights, we're building the tool we always wanted — making insights fast, affordable, and actionable for creators, entrepreneurs, and global brands.

We're hiring a mid-level full-stack engineer to join our team and own features end-to-end.

What you'll do:

Build and ship product across our React frontend and Node.js backend
Translate Figma and wireframes into clean, pixel-accurate code
Debug UI and backend issues using Chrome/Firefox dev tools
Write tests, review PRs, collaborate via GitHub
You have:

3-5 years building production web apps
Strong HTML5, CSS3, and responsive layout skills
Familiar with ReactJS (functional components, state management)
Understanding of Node.js (front/back, npm)
Experience working with RESTful APIs
Understanding of Test Driven Development
Familiarity with Docker (running the app in containers locally, working in Dev containers)
Cursor experience (using AI daily)
Comfortable working in a team (PRs, code review, GitHub Actions)
