The project is a major, long-term digital transformation initiative within the European Public Finance sector. The primary objective is to fully modernize a critical, national-scale fiscal legacy platform, shifting from a monolithic architecture into a highly secure, cloud-native ecosystem. This is a high-stakes initiative to future-proof core financial systems, improve operational efficiency, and protect highly sensitive financial data at the federal level.

Job Responsibility

  • Analyzing and structuring complex business requirements, translating them into secure, scalable, microservices-based solutions
  • Contributing directly to the product and technical roadmap definition while actively supporting the migration from legacy systems
  • Partnering with Enterprise Architects to design and secure modern API-first and event-driven patterns
  • Facilitating Agile workshops, ceremonies, and collaborative sessions to maintain an incremental delivery model
  • Coordinating alignment between diverse business and IT stakeholders, while supporting technical change management across teams
  • Contributing to the continuous improvement of DevOps practices, automation, and delivery speed

Requirements

  • You live and breathe Java (Spring Boot), Angular, Kubernetes, and containerization
  • You have successfully designed and implemented production-grade API-first layouts and Event-driven architectures
  • You have deep architectural knowledge and hands-on roots in Java, Spring Boot, Angular, and REST APIs
  • You are comfortable dealing with both modern platforms and complex legacy environments (WebLogic, DB2, Monoliths/Mainframes)
  • You have practical experience with Kubernetes, containerization, and Event-driven architecture
  • You champion a strong DevOps culture with automated CI/CD pipelines, Git, and modern observability (ELK stack)
  • You come from a large, recognizable enterprise (ideally Banking or Insurance)
  • You understand how to manage and secure highly sensitive financial data under strict compliance frameworks such as DORA, NIS 2.0, and ISO 27001
  • You possess the leadership skills required to build, scale, and mentor multidisciplinary Agile squads (Scrum/SAFe) from scratch, driving technical change management and reducing technical debt
  • Your English is at a very high professional level
  • You are excellent at facilitating Agile workshops, collaborating with Enterprise Architects, and managing relationships with demanding corporate/public stakeholders

Nice to have

  • Prior experience working on large-scale digital transformation programs for government bodies, federal agencies, or international public institutions
  • Any professional proficiency in French or Dutch
  • Professional certifications related to cloud architecture (e.g., AWS, Azure, GCP), Kubernetes (CKA/CKAD), or IT security compliance
  • Formal certifications in scaled Agile frameworks, such as SAFe (e.g., SAFe Agilist, SAFe Architect) or advanced Scrum roles

What we offer

  • Long-term collaboration
  • Technical training, certifications, and skills development
  • Competence Center mentoring
  • Clear career path
  • Employee benefits package (Multisport, private healthcare, life insurance)
  • Friendly working atmosphere, team-building events, and team-building meetings

  • 6+ years in security architecture and/or platform engineering, with a track record of shipping production code. Principal / Staff-level depth, ideally in a high-velocity or quant / financial-services engineering culture
  • Deep, mechanical command of modern identity and authorisation: OIDC / OAuth2 / JWT — token issuance flows, claims design, and delegation / impersonation patterns
  • Hands-on HashiCorp Vault experience, including dynamic / short-lived secrets and the realities of migrating off long-lived tokens without breaking a large application estate at once
  • Keycloak policy modelling, ideally with the Terraform-driven configuration the firm already uses
  • Strong Terraform / IaC fluency — enough to design repeatable, self-service patterns that others adopt, rather than bespoke per-team setups
  • Working knowledge of the Active Directory + Entra legacy reality: nested groups, LDAP-backed role mapping, and the distribution-list-as-permission-group failure mode — able to design around the mess pragmatically
Job Responsibility
Job Responsibility
  • Design and ship IaC-driven, self-service identity patterns that roll out firm-wide without requiring a full Active Directory cleanup first
  • Define the currently undefined agentic runtime security model: containerised code execution, permission delegation to agents, and MCP-based tool access
  • Lead the transition from long-lived secrets toward ephemeral, time-based, risk-scored credentials, scoped to task duration and issued via JWT / OIDC
  • Layer LLM / software guardrails (policy-as-text plus human review) on top of whatever hard guardrails are feasible across the estate
  • Establish an opinionated onboarding standard (e.g. mandatory MCP interfaces) and win adoption through better defaults and developer experience, not mandate alone
  • Design SIEM integration, behavioural baselining, and anomaly detection for agentic workflows, and centralise siloed audit logs to satisfy both security and regulatory requirements
  • Take bounded beachheads (for example, authenticate users and then delegate scoped access to internal systems) from vague to delivered
