Dit betekent dat wij volop inzetten op de digitalisering van onze producten, processen en diensten. En daar kunnen we jouw skills goed bij gebruiken. Als ervaren back-end developer werk je binnen een startup-omgeving aan vernieuwende applicaties die wij op de markt willen zetten. Dit doe je in het hele ontwikkel-proces: van ontwerpen en coderen tot testen en implementeren. Binnen een agile (scrum) team in een Azure DevOps-omgeving schrijf je mee aan software met hoge usability, waarbij je rekening houdt met veiligheid, prestaties en schaalbaarheid. Je gebruikt diverse programmeertalen en ontwikkelframeworks om functionele specificaties en gebruikerseisen te vertalen naar oplossingen. Je voert regelmatig updates en patches uit om de beveiliging en functionaliteit te verbeteren. Daarnaast doe je code reviews en controleer je programmeerwerk (4-ogen principe).\nDit vind jij mooi om te doen:\nWerken binnen een startup-omgeving;\n\nMet collega’s innovatieve softwareoplossingen ontwikkelen voor in- en externe klanten;\n\nZelfstandig werken aan backend applicaties en bijdragen aan een nieuwe generatie ingenieurstools en producten;\n\nSamen met collega’s aan gave, innovatieve vraagstukken werken;\n\nVanuit de analyse oplossingen aandragen waaraan anderen nog niet hadden gedacht;\n\nHet opdoen en delen van nieuwe kennis via codereviews en intervisie met collega’s;\n\nWerken binnen een agile (scrum) team in een Azure DevOps omgeving.\n\nMet wie werk jij samen?\nJe gaat aan de slag binnen een startup-omgeving. Het is een relatief jong en gedreven team van data scientists en softwareontwikkelaars, die met veel enthousiasme werken aan innovatieve digitale oplossingen voor onze klanten. Hier lever je een belangrijke bijdrage aan de ontwikkeling van innovatieve softwareoplossingen. Ook zul je veel samenwerken én sparren met jouw collega’s uit onze landelijke ontwikkelaars-community én ons centraal innovatieteam. Dit zijn ondernemende en gedreven collega’s die met elkaar vormgeven aan onze digitale strategische doelen. Daarnaast trek je veel op met onze domein-experts: adviseurs en projectleiders uit verschillende businesslijnen.\nRequirements\nDit breng jij mee:\nMinimaal hbo werk- en denkniveau;\n\nMeedenken over en kunnen werken binnen commerciële en technische kaders;\n\nMinimaal 5 jaar ervaring met softwareontwikkeling in .NET en Python;\n\nErvaring met Django/FastAPI;\n\nKennis van Azure Cloud en SQL Databases (PostgreSQL);\n\nErvaring met Websockets, RPC, HTTP, (REST) API’s en microservices;\n\nErvaring met geautomatiseerde testen;\n\nErvaring met CI/CD pipelines en docker, kennis van HTML/CSS/Javascript/Typescript is een pré.","description_format":"text","description_chars":2870,"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":[{"language":"German","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Environmental Science","Engineering Services"],"lifecycle":[{"event":"open","at":"2026-09-10T18:09:45Z"},{"event":"open","at":"2026-09-25T17:18:55Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.562,"p_room":0.36,"age_days":257,"expected_fill_days":168,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/anteagroup-ervaren-back-end-developer","json_url":"https://alion.io/job/anteagroup-ervaren-back-end-developer.json","meta":{"generated_at":"2026-10-29T12:04:51Z","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":18048,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":668718},"rest":"https://alion.io/mcp/rest/get_company?id=668718"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fanteagroup-ervaren-back-end-developer"},{"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%2Fanteagroup-ervaren-back-end-developer"},{"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%2Fanteagroup-ervaren-back-end-developer"},{"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/anteagroup-ervaren-back-end-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fanteagroup-ervaren-back-end-developer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":610330}},{"tool":"search_jobs","arguments":{"company":"anteagroup.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":610330},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
