We are looking for a Senior Enterprise Architect to help shape the technical and functional architecture of the Simpl Programme, a strategic European initiative focused on enabling secure, interoperable, and future-ready data spaces.

In this role, you will provide architectural leadership across Simpl-Open and its wider ecosystem. You will help ensure consistency between functional and technical architecture, support integration with other European platforms and initiatives, and translate regulatory, interoperability, and security requirements into scalable technical solutions.

Working in a complex, multi-stakeholder environment, you will connect policy, architecture, security, and technology, collaborating with European institutions, programme governance teams, technical experts, and delivery partners.

Key Responsibilities

Architecture Definition: Define, maintain, and evolve the functional and technical architecture for Simpl-Open, including component architectures, data flows, interfaces, and deployment models.
Architecture Governance: Ensure architectural consistency across the programme and contribute to architecture principles, standards, design decisions, and lifecycle governance.
EU Interoperability: Align architectural choices with relevant European interoperability standards and frameworks, including CIM, SAREF, AS4, EIRA, and eGovERA.
Programme Collaboration: Work closely with the Simpl Programme Support Office and other programme stakeholders on quality assurance and lifecycle governance, incorporating relevant programme guidelines and development standards.
Ecosystem Integration: Support the integration of Simpl services with DOME and relevant European initiatives such as GAIA-X, EuroHPC, and AI Factories.
Security & Privacy: Embed Security-by-Design and Privacy-by-Design principles into architecture decisions and contribute to alignment with applicable requirements such as GDPR, eIDAS, the Data Act, and relevant cybersecurity requirements.
Federated Architecture: Promote open standards, modular building blocks, federated architecture principles, connectors, and trust frameworks that enable interoperability across distributed ecosystems.
Technical Guidance: Provide architectural guidance to technical and delivery teams, assessing solution designs and helping resolve complex architecture and integration challenges.
Stakeholder Engagement: Facilitate architecture discussions and workshops with EU stakeholders, contractors, technical experts, and governance bodies.
Architecture Communication: Translate complex architecture decisions into clear recommendations, documentation, and roadmaps for both technical and non-technical stakeholders.
