FullStack Developer Frontend Focus

About this role

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

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

Our Tech Stack
TypeScript, 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.
