In werkelijkheid is mainframe relevanter dan ooit. Het is het kloppend hart van de systemen die ontelbare transacties mogelijk maken voor onze bank- en verzekeringsactiviteiten, elke dag opnieuw.\nAls Mainframe Software Engineer verdiep je je in een complexe wereld van bedrijfskritische applicaties die een uptime vragen van tegen de 100% – iets wat enkel met het mainframe mogelijk is. Je schrijft robuuste code, stelt kwaliteit voorop en draagt bij tot de stabiliteit van systemen waar duizenden klanten op rekenen.\nOp vandaag evolueert het mainframe door modernisering, automatisering en aansluiting op hedendaagse DevOps‑werkwijzen. In deze rol maak jij die evolutie mee vanop de eerste rij.\nJe maakt deel uit van een divers team waarin samenwerken, leren en kennis delen centraal staan in een technisch domein met een verzekerde toekomst.\nWat verwachten we van jou?Je werkt samen met collega-software engineers om nieuwe features te ontwikkelen en onze toepassingen te onderhouden. Dat betekent niet dag en nacht code schrijven. Je zet je kennis van programmeertalen in om in bestaande programma’s te werken of data op te halen. Je zal zowel zelf programmeren als code reviews doen.\nSamen met applicatiebeheerders test je nieuwe toepassingen of wijzigingen.\nCollega’s kunnen bij jou terecht met operationele vragen. Je zoekt zaken uit, vindt de oorzaak van eventuele problemen en bedenkt oplossingen.\n\nJouw troeven?Dankzij een bachelor- of masterdiploma en min. 5 jaar ervaring in IT heb je al een sterke technische kennis.\nJe hebt ervaring in:software development (backend)\nmainframe-technologieën als COBOL, JCL, DB2 en IMS\nontwikkel- en releaseprocessen als CI/CD en GitHub.\n\nJe maakt je complexe materie snel eigen en ziet de verbanden, ook in een context met minimaal uitgetekende krijtlijnen.\nJe hebt oog voor kwaliteit, standaarden & klantentevredenheid.\nJe communiceert vlot in het Nederlands en Engels. Zo werk je vlot samen met anderen, ook je collega’s in het buitenland. Vragen stellen of ideeën challengen? Voor jou geen probleem.","description_format":"text","description_chars":2132,"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":"2026-10-11T20:36:23Z"}],"visa":[],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":1,"p_active":0.516,"p_room":1,"age_days":0,"expected_fill_days":20,"reasons":["seen:0","agency","win:early","comp:brand"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/editx-mainframe-software-engineer","json_url":"https://alion.io/job/editx-mainframe-software-engineer.json","meta":{"generated_at":"2026-10-12T21:40:55Z","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":35376,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":4413081},"rest":"https://alion.io/mcp/rest/get_company?id=4413081"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Feditx-mainframe-software-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%2Feditx-mainframe-software-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%2Feditx-mainframe-software-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/editx-mainframe-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Feditx-mainframe-software-engineer"}]}
