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.\nThis is a backend-first role: about 70% backend (Python, some Node.js) 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.\nKey Responsibilities\nDesign, build and maintain Python services and APIs behind the funnel: registration, booking and the visitor account\n\nBuild and own server-side integrations with ad platforms (Meta CAPI, TikTok Events API and similar): event delivery, deduplication, retries and monitoring\n\nOwn attribution on the backend: end-to-end visit tracking, UTM persistence, and diagnosing gaps in V2L/V2B data\n\nKeep services fast and reliable: caching, query optimization, debugging server-side rendering in our Node.js/Express layer\n\nInvestigate production incidents through Sentry and see them through to resolution\n\nSupport A/B testing on the server side: feature flags, rollouts, and cleanup after experiments\n\nShip frontend changes in React/TypeScript when a feature needs it\n\nRequirements\nRequirements\n5+ years of production backend development in Python, including services you designed, shipped and supported in production yourself\n\nStrong backend fundamentals: API design, relational databases and SQL, caching, background jobs, and integrating third-party APIs (auth, rate limits, retries, idempotency)\n\nProduction debugging experience: logs, error tracking, finding the root cause of an issue\n\nNode.js: comfortable reading and changing an Express service\n\nWorking frontend skills: enough TypeScript and React to deliver a feature end-to-end. Expert level not required.\n\nAn understanding of how tracking data travels from click to report, and the ability to find where it gets lost\n\nProduct mindset: you work with metrics and hypotheses, not just tickets\n\nFluent English\n\nNice to Have\nServer-side conversion tracking (CAPI, Events API, server-side GTM)\n\nBigQuery: checking your own hypotheses with data\n\nCDN and edge caching (CloudFront or similar)\n\nGDPR and consent mechanisms\n\nE2E testing with Playwright or Cypress\n\nOur Tech Stack\nPython, Node.js, Express (SSR), TypeScript, React, Next.js, Sentry, GrowthBook, BigQuery.\nWhat we offer\nFully remote work\n\nA chance to shape the future of AI-driven education\n\nA fun, dynamic team that loves building innovative products\n\nUnlimited holidays, because we trust you to deliver","description_format":"text","description_chars":2884,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Serbia","iso":"RS","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Language Learning","E-learning"],"lifecycle":[{"event":"open","at":"2026-10-19T08:09:49Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":0,"expected_fill_days":38,"reasons":["conf:2","stale_co","velocity","win:early"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/novakid-python-backend-developer-fullstack-capable-remote","json_url":"https://alion.io/job/novakid-python-backend-developer-fullstack-capable-remote.json","meta":{"generated_at":"2026-10-20T08:59:54Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9882,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":678723},"rest":"https://alion.io/mcp/rest/get_company?id=678723"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnovakid-python-backend-developer-fullstack-capable-remote"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fnovakid-python-backend-developer-fullstack-capable-remote"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fnovakid-python-backend-developer-fullstack-capable-remote"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/novakid-python-backend-developer-fullstack-capable-remote\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnovakid-python-backend-developer-fullstack-capable-remote"}]}
