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. 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: caching, query optimization, debugging server-side rendering in our layer Investigate production incidents through Sentry and see them through to resolution Support A/B testing on the server side: feature flags, rollouts, and cleanup after experiments Ship frontend changes in React/TypeScript when a feature needs it Requirements Requirements 5+ years of production backend development in Python, including services you designed, shipped and supported in production yourself Strong backend fundamentals: API design, relational databases and SQL, caching, background jobs, and integrating third-party APIs (auth, rate limits, retries, idempotency) Production debugging experience: logs, error tracking, finding the root cause of an issue : comfortable reading and changing an Express service Working frontend skills: enough TypeScript and React to deliver a feature end-to-end. Expert level not required. An understanding of how tracking data travels from click to report, and the ability to find where it gets lost Product mindset: you work with metrics and hypotheses, not just tickets Fluent English Nice to Have Server-side conversion tracking (CAPI, Events API, server-side GTM) BigQuery: checking your own hypotheses with data CDN and edge caching (CloudFront or similar) GDPR and consent mechanisms E2E testing with Playwright or Cypress Our Tech Stack Python, , Express (SSR), TypeScript, React, , Sentry, GrowthBook, BigQuery.
