Job summary

Novakid School is building an online English learning funnel and seeks a backend-focused engineer to own Python services and server-side integrations that power registration, booking and visitor accounts. You will implement API design, data tracking, and ad-platform integrations with a mix of frontend work in React/TypeScript as needed.

You’ll work end-to-end in a backend-first environment, owning production services, debugging incidents, and supporting A/B tests.

Qualifications

• 5+ years of production backend development in Python.
• Strong backend fundamentals: API design, relational databases and SQL, caching, background jobs, and integrating third-party APIs.
• Production debugging experience: logs, error tracking, finding the root cause of an issue with an Express service.
• Working frontend skills: enough TypeScript and React to deliver a feature end-to-end.
• Fluent English.

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

Job description

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

• 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

What we offer

• Fully remote work
• A chance to shape the future of AI-driven education
• A fun, dynamic team that loves building innovative products
• Unlimited holidays, because we trust you to deliver
