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.

• 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 Type Script 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

• GDPR and consent mechanism implementation on public pages

• Headless Word Press

• End-to-end testing with Playwright or Cypress

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

• CDN and edge caching (Cloud Front or similar)

• Hands-on experience with Sentry and handling production errors

Type Script, React, Python, Next.js, Node.js, Express with server-side rendering via Pug, Sass and PostCSS, Vite and Gulp, MUI and an in-house design system in Storybook, Vitest, Jest, Cypress, and Playwright for E2E testing.
