Het huidige spooraandeel bedraagt ongeveer 7%. Het programma richt zich op een aantrekkelijker en efficiënter spoorvervoer in de havenzones.\nEen belangrijk onderdeel is de ontwikkeling van een digitaal spoorplatform voor de uitwisseling van informatie tussen de betrokken partijen, waaronder de havenorganisatie, de spoorinfrastructuurbeheerder, spoorwegoperatoren, terminals, verladers en industriële partners.\nOm de verkeersstromen in de havenzones beter te sturen en te optimaliseren, wordt een toepassing geanalyseerd en gerealiseerd die end-to-endtransparantie biedt over het door-to-door-goederenvervoer per spoor. De toepassing brengt gegevens uit verschillende bronnen samen en visualiseert die. Zo kunnen treinen, wagons en hun lading vanaf vertrek tot aankomst worden opgevolgd door de verschillende stakeholders in de vervoersketen.\nJe maakt deel uit van een agile DevOps-team dat applicaties en componenten voor de haven en de havengemeenschap ontwikkelt en beheert. Als Technical Lead neem je een leidende rol op, stuur je het ontwikkelteam aan en coach je ontwikkelaars.\nJouw profiel\nJe brengt de volgende kennis, ervaring en vaardigheden mee:\nZeer grondige kennis van Java, Java API's en Spring Boot, in combinatie met ervaring in de ontwikkeling van Java-gebaseerde applicaties.\nKennis van microservices en Spring.\nKennis van SQL-databases, zoals Oracle.\nEen sterke focus op clean code en Clean Architecture.\nKennis van Infrastructure as Code (IaC) en Terraform.\nJe bent een Certified Java Developer.\nJe kunt een ontwikkelteam leiden en ontwikkelaars coachen.\nJe voert programmatieopdrachten zeer vlot uit, waaronder coderen, testen en debuggen.\nKennis van BPMN en Domain Driven Design (DDD).\nKennis van DevOps-principes en ervaring met agile ontwikkelmethoden, waarbij je een leidende rol kunt opnemen.\nKennis van Git, Jenkins, Sonar en Jira.\nKennis van Figma, Grafana, Hibernate, Kafka, KendoUI, Kubernetes en S3 storage.\nErvaring met projecten in het domein van railways en spoorwegen.\nErvaring met het ontwikkelen, testen en uitrollen van businessapplicaties in een 24x7-context.\nProfessionele en heldere communicatie in het Nederlands en Engels.\nJe functioneert goed in multidisciplinaire teams.\nDeze functie wordt aangeboden als een deeltijdse freelance rol (80%).","description_format":"text","description_chars":2458,"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":"Dutch","level":"All
