Job description

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, TikTok 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

Job requirements

• 3+ years of production experience with TypeScript and React

• Python and Node.js: ability to work independently on the backend—endpoints, caching, SSR debugging—beyond just a thin BFF (Backend-For-Frontend) layer

• Experience with analytics and tracking: GTM, event tracking, server-side conversion delivery. Understanding how data travels from click to report, and the ability to locate data leaks/loss

• Product mindset: working with metrics and hypotheses rather than just closing tickets

• English proficiency

Nice to Have

• GDPR and consent mechanism implementation on public pages

• Headless WordPress

• End-to-end testing with Playwright or Cypress

• SQL and BigQuery—ability to self-verify hypotheses using data

• CDN and edge caching (CloudFront or similar)

• Hands-on experience with Sentry and handling production errors
