API REST/JAVA/DevOps/Agile SCRUM/UML/JSON & XML/Windows, Linux
On behalf of our clients operating in the public sector, we are recruiting Senior Java developers for long-term assignments.
As a Senior JAVA developer, you will be involved in new and ongoing projects within large development teams to improve efficiency and deliverables. You will join a strategic programme aimed at the complete rewrite of a critical monolithic application — comparable to a banking platform (managing payments, accounts, and reimbursements) combined with an accounting system — into a modern, modular, and scalable microservices architecture.
Tasks:
The developer will join one of the key priority groups: accounting management, transaction and order management, rules management, or interface management.
Actively participate in the Scrum team's dynamics and develop features based on prior functional and technical analysis.
Perform unit testing to ensure code quality and reliability.
Work in continuous collaboration with the functional analyst and testers from the beginning of each story.
Demonstrate strong anticipation skills, ensure smooth inter-team communication, organizational flexibility, commitment to quality and maintain a high level of technical rigor.
As a Senior Consultant, actively transfer knowledge to junior collaborators
Profile:
Required Senior-Level Experience
Java (advanced development expertise), REST APIs (including BelgIF standards), asynchronous messaging (Command/Reply & Event-driven architectures), Spring Boot and Angular
DB2 and SQL
DevOps tools & platforms: Kubernetes, ArgoCD, Vault, GitLab, Git, Agile SCRUM methodology
Operating systems: Windows & Linux
UML, and data formats JSON & XML
Fluent in French or Dutch + very good English
Very useful experience:
WebLogic, ELK, Atlassian Suite (Jira, Confluence)
Intellij, Visual Studio Code, Eclipse, NetBean, Github, fisheye, ActiveMQ, Cucumber,etc..
What we offer:
We offer Permanent contracts as well as Freelancing contracts for long term missions. Employees are offered a full salary package in line with the market and including many incentives (meal vouchers, insurances, 13th & 14th month, transport subscription and/or company car, etc.)
We care about your satisfaction by following up your mission and supporting you with the highest attention.
Therefore with Aubay, Employees or Freelancers are equally considered as part of the company
