Je stuurt niet noodzakelijk een team aan, maar neemt wel technisch ownership, deelt kennis en helpt mee richting geven aan hoe Next.js binnen projecten wordt ingezet.\n\nDe samenwerking is mogelijk in vast dienstverband of op freelancebasis. In beide gevallen zoeken we iemand die zich voor langere tijd aan het team en de technologie wil verbinden.\nWat ga je doen?\nJe bouwt en optimaliseert moderne webapplicaties binnen grotere digitale ecosystemen: meerdere markten of talen, verschillende integraties en platformen die voortdurend verder evolueren.\n\nConcreet:\nontwikkel je complexe applicaties met Next.js, React en TypeScript;\nneem je inhoudelijk de lead op rond Next.js;\ndenk je mee over de technische opzet en architectuur van oplossingen;\nmaak je onderbouwde keuzes rond rendering, data fetching, caching en performance;\nintegreer je frontendoplossingen met API's, back-endservices en andere platformen;\nbewaak je codekwaliteit, testing, onderhoudbaarheid en schaalbaarheid;\nhelp je technische afspraken en best practices rond Next.js mee vormgeven;\nonderzoek je complexe technische problemen en werk je structurele oplossingen uit;\nbespreek je technische keuzes en hun impact helder met collega's en klanten;\ndeel je kennis en spar je met andere developers over technische vraagstukken.\nJe technische expertise is daarbij je belangrijkste vorm van leiderschap.\n\nWie zoeken we?\nWe zoeken geen React Developer die Next.js af en toe heeft gebruikt.\nJe hebt professionele, hands-on ervaring met Next.js in productieomgevingen en voldoende technische maturiteit om zelfstandig verantwoordelijkheid op te nemen en inhoudelijk richting te geven.\nJe hebt een sterke basis in:\nNext.js, React en TypeScript/JavaScript;\nmoderne frontendarchitectuur;\nAPI-integraties;\ntesting en code reviews;\nperformance-optimalisatie;\nCI/CD en moderne development workflows.\nJe begrijpt hoe technische keuzes invloed hebben op performance, rendering, schaalbaarheid, onderhoudbaarheid en user experience.\n\nDaarnaast kijk je verder dan je eigen code. Je onderzoekt alternatieven, stelt bestaande oplossingen in vraag wanneer nodig en kunt technische beslissingen helder onderbouwen.\nWe zoeken een sterke medior of senior engineer die vanaf de start zelfstandig kan meedraaien en voldoende expertise heeft om als technisch referentiepunt rond Next.js te fungeren.\n\nExtra interessant\nErvaring met enterprise web- of e-commerceplatformen, headless/composable architecturen, Node.js, GraphQL, CMS-technologie, cloud, Vercel of commerceplatformen is een plus.\nJe hoeft niet alles af te vinken.\nBelangrijker is dat je ervaring hebt met voldoende complexe digitale omgevingen om te begrijpen hoe verschillende technologieën, integraties en afhankelijkheden samen één platform vormen.","description_format":"text","description_chars":3375,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-11T19:30:43Z"}],"visa":[],"liveness":{"score":21,"band":"cold","label":"Long shot","p_open":0.6,"p_active":0.645,"p_room":0.55,"age_days":31,"expected_fill_days":30,"reasons":["seen:31","win:tail"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/headcount-lead-next-js-engineer-enterprise-platforms-freelancevast","json_url":"https://alion.io/job/headcount-lead-next-js-engineer-enterprise-platforms-freelancevast.json","meta":{"generated_at":"2026-10-27T13:41:03Z","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":1978,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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":4413115},"rest":"https://alion.io/mcp/rest/get_company?id=4413115"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fheadcount-lead-next-js-engineer-enterprise-platforms-freelancevast"},{"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%2Fheadcount-lead-next-js-engineer-enterprise-platforms-freelancevast"},{"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%2Fheadcount-lead-next-js-engineer-enterprise-platforms-freelancevast"},{"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/headcount-lead-next-js-engineer-enterprise-platforms-freelancevast\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fheadcount-lead-next-js-engineer-enterprise-platforms-freelancevast"}]}
