About this role
Novakid is an online English school for kids. The Visitor Squad is responsible for the funnel from the first visit to the paid lesson: landing pages, registration and booking, blog, and the visitor’s personal account. We measure our performance using two key metrics—visitor → lead and visitor → booking—and validate almost everything we do through experimentation. A core role within the team: approximately 70% frontend and 30% backend. Your area of responsibility includes the visitor’s personal account, attribution and funnel tracking, server-side integrations with ad platforms, and supporting experiments. You will work within the squad's processes: planning, grooming, code reviews, sprints, and releases.
