FullStack Developer Frontend Focus (Remote)

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.

Key Responsibilities

Develop and maintain the visitor’s personal account and parts of the funnel from landing pages to booked lessons Own attribution: end-to-end visit tracking chains, UTM parameters, and diagnosing gaps in V2L/V2B tracking Build server-side integrations with ad platforms (e.g., Meta CAPI, Tik. Tok Events API, and similar) Write and debug backend code in Python/Node: endpoints, caching, and server-side rendering Support A/B testing: rollouts, feature flags, and post-experiment code cleanup Investigate production incidents via Sentry and drive them through to resolution Monitor and optimize public page speed: Core Web Vitals 3+ years of production experience with TypeScript and React Python and Node.
