Een plek waar vakmanschap de norm is, kennisdeling vanzelfsprekend, en jij de ruimte krijgt om te excelleren met collega’s die je inhoudelijk beter maken. Geen hype, geen snelle groei. Wel een cultuur waarin je serieus genomen wordt en impact maakt op projecten die ertoe doen.\nSluit jij je aan bij een engineering cultuur die je uitdaagt en beter maakt?\nTaken\nJe werkt aan complexe, cloud-native oplossingen voor toonaangevende organisaties in Nederland. In omgevingen waar schaalbaarheid, security en performance core business zijn. Je hebt invloed op architectuurkeuzes en werkt in teams waar kwaliteit boven buzzwords gaat.\nZo maak jij impact\nOntwerp en bouw high-performance, cloud-native services met Spring Boot in Java 21+ en/of Kotlin.\nWerk met event-driven architecturen waarin dagelijks (honderden) miljoenen events worden verwerkt.\nRicht CI/CD-pipelines in en deploy via GitOps met Kubernetes en ArgoCD op Azure, AWS of GCP.\nNeem eigenaarschap over architectuur, performance en reliability (SLO’s/SLA’s, resilience-patterns, idempotency, backpressure).\nObserveer en optimaliseer met metrics/logging/tracing (Prometheus/Grafana/OpenTelemetry) en security-by-design (OAuth2/OIDC, secrets, policies).\nVersnel met agentic AI zoals Claude, Cursor en Junie.\nDeel kennis actief binnen onze community en bij klanten.\nVereisten\nWat breng je mee?\nMinimaal 5 jaar ervaring als software engineer (hbo/wo of aantoonbaar gelijkwaardig niveau).\nSterke kennis van Java (21+) en/of Kotlin.\nErvaring met Spring Boot, cloud-native development en event-driven architectuur.\nBekend met Kubernetes en het inrichten van CI/CD pipelines d.m.v. GitOps.\nErvaring met Kafka of vergelijkbare messaging-technologieën.\nErvaring met AWS, Azure, of GCP.\nPluspunt: kennis van frontend frameworks zoals Angular of React voor full-stack eigenaarschap.\nJe spreekt vloeiend Nederlands en bent communicatief sterk. \nJe vindt het leuk om kennis te delen en kunt technische keuzes, op verschillende niveaus, helder uitleggen.\nBenefits\nKeuzevrijheid in beloning:\nVast salaris: €5.000 - €8.000 + bonus\nOf een aantrekkelijke 70/30-regeling\nJij kiest hoe je reist: Goede leaseregeling of mobiliteitsvergoeding.\nHybride werken.\nInvestering in jouw groei: Ruim opleidingsbudget en toegang tot conferenties.\nEen echte engineering community: Collega’s die precies weten wat er speelt in de markt.\nGoede basis: Pensioen en collectieve verzekeringen.\nProjecten die ertoe doen: Kritische systemen in fintech, energie, infrastructuur en overheid.\nWat maakt ons anders?\nEngineering-led leadership: Onze richting wordt bepaald door ervaren engineers die zelf nog dagelijks coderen en spreken op internationale conferenties. Keuzes zijn inhoudelijk, niet politiek.\nSamen naar conferenties: We gaan samen naar conferenties en meetups. Heb je de ambitie om te spreken? We helpen je d.m.v. coaching, dry-runs en reviews.\nWe nemen jou serieus: Geen “superhero’s”, “ninjas” of “wizards”. Jij bent een professional. Je krijgt vertrouwen, autonomie en echte inhoudelijke verantwoordelijkheid.\nOpdrachtkeuzes maken we samen: Projecten waar je trots op bent, gebaseerd op jouw groeipad.\nEen echte engineering cultuur: Een community die je uitdaagt én beter maakt.\nBewuste schaal: Korte lijnen, directe invloed. Jouw stem weegt.\nWaarom je bij ons past\nJe wilt werken aan systemen die niet mogen falen, met collega’s die kwaliteit serieus nemen. Je zoekt autonomie, vertrouwen en een stem in technische keuzes. Dat is precies wat je hier krijgt, in een community die je uitdaagt én beter maakt.\nKlaar om het verschil te maken?\nLaat je werk spreken. Deel je GitHub, LinkedIn of cv en laat ons zien waar je trots op bent: een repo, een architectuurschets of een interessante trade-off die je onlangs maakte.","description_format":"text","description_chars":3814,"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},{"language":"Dutch","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development","Enterprise Apps Implementation Partners"],"lifecycle":[{"event":"open","at":"2026-10-14T11:49:06Z"},{"event":"close","at":"2026-10-14T19:33:51Z"},{"event":"reopen","at":"2026-10-15T03:42:04Z"},{"event":"close","at":"2026-10-15T12:05:12Z"},{"event":"reopen","at":"2026-10-16T21:40:29Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.838,"p_room":0.72,"age_days":311,"expected_fill_days":877,"reasons":["conf:4","win:mid","crowd:"],"computed_at":"2026-10-24T06:02:35Z"},"pay":{"stated_usd_annual":107976,"is_top_pay":false},"html_url":"https://alion.io/job/creetion-senior-javakotlin-engineer","json_url":"https://alion.io/job/creetion-senior-javakotlin-engineer.json","meta":{"generated_at":"2026-10-25T02:15:01Z","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":3401,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":673984},"rest":"https://alion.io/mcp/rest/get_company?id=673984"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcreetion-senior-javakotlin-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%2Fcreetion-senior-javakotlin-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%2Fcreetion-senior-javakotlin-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/creetion-senior-javakotlin-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcreetion-senior-javakotlin-engineer"}]}
