General Context

The organization operates in a complex technological environment combining a legacy application landscape and modern components. The context includes a structural transformation of the IT landscape, modernization of architectures, reduction of technical debt, adoption of Cloud, and compliance with regulatory requirements, notably NIS2.

The existing applications cover critical areas such as unemployment regulation (payments, debt management, financial and accounting processing). Part of these systems relies on legacy technologies, while new Cloud/hybrid architectures are emerging. The architect plays a key role in harmonizing, securing, and ensuring the consistency of these architectures.

Main Responsibilities

1. Vision and Architectural Design

• Define, review, and maintain coherent, scalable, and secure Cloud/hybrid architectures.
• Translate enterprise architecture directions into concrete technical models.
• Design aligned, high-performance, and maintainable application and data architectures.
• Ensure that architectural decisions support business objectives.

2. Security, Compliance, and Resilience

• Integrate security from the design phase (security by design).
• Design secure architectures: network segmentation, robust IAM, access management, encryption.
• Translate NIS2 requirements into concrete technical measures.
• Promote secure coding practices and mechanisms for monitoring and auditability.

3. Support for Development Teams

• Perform technical analyses within business projects.
• Advise on integrations, data models, performance, and scalability.
• Support teams in adopting technologies and architectural patterns.
• Initiate or validate Proof-of-Concepts.

4. Governance and Quality

• Organize and lead design reviews.
• Ensure compliance with architectural standards and best practices.
• Continuously improve the maintainability, security, and decoupling of systems.
• Systematically document architectural choices.

5. Collaboration and Change Management

• Ensure communication between business, development, security, and infrastructure teams.
• Explain technical choices clearly and accessibly.
• Support collective decision-making and manage the convergence of visions.
• Contribute to upskilling teams.

6. Expertise and Problem Solving

• Analyze and resolve complex technical problems in a highly interconnected environment.
• Ensure the coherence of legacy and modern components.

Required Technical Skills

• Proven experience (10+ years) in designing complex IT architectures.
• Mastery of Cloud environments (GCP, Azure, AWS) and Cloud-native principles.
• Expertise in modern Java (Spring, microservices, API-driven, event-driven).
• Skills in containerization and orchestrators (OpenShift).
• Advanced knowledge of relational databases (MySQL) and data modeling.
• Knowledge of integrations: messaging, REST/GraphQL, event-driven.
• Knowledge of resilient and high-availability architectures.
• Understanding of security standards (NIS2).

Behavioral Skills

• Excellent analytical and synthesis skills.
• Structured and educational communication.
• Collaborative leadership, ability to unite and support.
• Global vision and ability to maintain an overview.
• Quality-oriented, autonomous, and proactive.
• Ability to connect business needs with technical challenges.

Education

• Master’s degree in computer science or engineering, or equivalent experience.
• Cloud or architectural certifications are an asset.

Language Skills

• Very good command of French, Dutch, and English.
