Python Backend Developer, Fullstack-capable

Remote, Worldwide

Novakid is an online English school for kids. The Visitor Squad owns the funnel from first visit to paid lesson: landing pages, registration and booking, blog, and the visitor's personal account. We track two key metrics, visitor → lead and visitor → booking, and test almost everything we ship through experiments.

This is a backend-first role: about 70% backend (Python, some ) and 30% frontend (React/TypeScript). You'll own the server side of the funnel: APIs behind registration, booking and the visitor account, attribution, and server-side integrations with ad platforms. When a feature needs frontend work, you'll take it end-to-end yourself. You'll work within the squad's processes: planning, grooming, code review, sprints and releases.

Key Responsibilities

Design, build and maintain Python services and APIs behind the funnel: registration, booking and the visitor account

Build and own server-side integrations with ad platforms (Meta CAPI, TikTok Events API and similar): event delivery, deduplication, retries and monitoring

Own attribution on the backend: end-to-end visit tracking, UTM persistence, and diagnosing gaps in V2L/V2B data

Keep services fast and reliable:...
