On behalf of our fast-growing division, we are looking for API/SOA Developers at different seniority levels (Junior, Medior, and Senior) to join our consultant pool in Brussels.

In this role, you will be key to developing, securing, and maintaining modern API and Service-Oriented Architectures (SOA). Working on behalf of our premier client in Brussels, you will build clean, secure integrations and play a central part in bridging legacy systems with modern cloud infrastructure.

API & SOA Development: Developing high-quality backend APIs and services using Java within SOA, REST, and event-driven architectures.
API Management & Integration: Implementing and configuring integration points across enterprise platforms such as Axway, Apigee, or WSO2.
Security & Vulnerability Management: Incorporating robust security standards (OAuth2, JWT, SOAP security) and securing code using tools like Snyk and PKI (Public Key Infrastructure).
Cloud & CI/CD Pipelines: Deploying and managing applications within Public Cloud environments, actively utilizing Git and automation-driven CI/CD pipelines.
Testing & Quality Assurance: Conducting thorough automated testing of web services to ensure system stability, resilience, and high performance.
Agile Collaboration: Working within an Agile/Scrum framework, using Jira and Confluence for documentation, tracking, and sprint activities.

Your Profile

Experience:
- Junior: ~1 year of experience in backend/API development.
- Medior: ~3 years of solid experience in API & middleware development.
- Senior: 10+ years of deep expertise in complex enterprise integration and software development.
Core Technical Skills:
- Proficient in Java development applied to APIs.
- Strong knowledge of API/Web Service standards and protocols (OAuth2, JWT, SOAP).
- Hands-on experience with API Gateway / ESB platforms such as Axway, Apigee, or WSO2.
- Familiarity with Event-Driven Architecture and public cloud concepts.
- Solid understanding of security tools and practices (Snyk, PKI).
- Experience with Git, CI/CD workflows, and web services testing frameworks.
Methodology: Comfortable working in Agile/Scrum squads with tools like Jira and Confluence.
Languages: Working proficiency (minimum 3/4) in English OR French/Dutch.

The Recruitment Steps

First Contact: A phone call to discuss your aspirations and what we can offer you.
Meeting: An opportunity to get to know each other and explore your professional background.
