Donna gaat vervangen worden, maar moet nog minimaal 7 jaar goed werken. Om dit te bereiken willen we de laag tussen server en applicatie én de voorbrenging (inclusief testen) zo automatiseren en standaardiseren dat het systeem zonder verrassingen en handmatige acties in de lucht blijft. Het ultieme doel is dat er uiteindelijk elke twee weken een release zonder incidenten naar productie kan.\nConcreet bouw je mee aan:\nEen reproduceerbare, versie-geparametriseerde runtime-stack vanuit code, zó opgezet dat een toekomstige infra/platform/tool-upgrade een pipeline-wijziging is, geen project.\nGeautomatiseerde omgevingen opzetten inclusief data- en configuratiemanagement.\nEen technisch afgedwongen voortbrengings- en testproces met quality gates die promotie blokkeren/begeleiden. \nDataonafhankelijk en geautomatiseerd testen.\nMigratie naar een Grafana-observabilitystack voor de monolitische applicatie. \nVereenvoudiging van authenticatie en autorisatie binnen het systeem.\nJe gaat aan de slag in een nieuw op te zetten team bestaande uit ongeveer 5 engineers, een aantal testexperts, een product onwer, een service manager en een architect. Jij bent één van medior engineers die de technische lat hoog legt.","description_format":"text","description_chars":1368,"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":"2026-10-09T14:13:10Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.227,"p_room":0.36,"age_days":95,"expected_fill_days":49,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":{"stated_usd_annual":84108,"is_top_pay":false},"html_url":"https://alion.io/job/prorail-medior-platform-engineer","json_url":"https://alion.io/job/prorail-medior-platform-engineer.json","meta":{"generated_at":"2026-10-26T05:29:49Z","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":7401,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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":1835079},"rest":"https://alion.io/mcp/rest/get_company?id=1835079"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprorail-medior-platform-engineer"},{"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%2Fprorail-medior-platform-engineer"},{"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%2Fprorail-medior-platform-engineer"},{"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/prorail-medior-platform-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprorail-medior-platform-engineer"}]}
