Python Backend Developer, Fullstack-capable

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
