Overview

Enterprise Architect with 10+ years of experience, skilled in ARB facilitation, decision packs, and stakeholder engagement. Proficient in ITIL, TOGAF, ArchiMate, cloud-native patterns, microservices, event-driven architectures, and portfolio management tools. Advocates reference architectures and bridges Business, IT, Architecture, and Infrastructure teams.

Job Responsibilities

  • Lead the definition and continuous improvement of the governance framework, including principles, standards, policies, reference architectures, and golden scenarios, within a clear ARB decision workflow (decision packs, traceability and escalation path).
  • Contribute to the implementation of a federated target operating model and ensure alignment with the company Digital Platform (EDP) by translating EDP guardrails into consumable guidance for local delivery.
  • Support the Head of IT Architecture in strategic studies, evaluations, and decision-making discussions.
  • Coach and provide guidance to other architecture roles across the organisation.
  • Communicate the application strategy and related processes to business and IT stakeholders within the company.
  • Collect and analyse business gaps—using business and IT surveys—to assess and evaluate the IT landscape, in close collaboration with business architecture.
  • Conduct cross-domain trade-off analyses using industry-recognised methods (e.g., ATAM) and cost-benefit analyses (e.g., CBAM) to deliver well-founded architectural recommendations. 
  • Give directions to maintain and evolve the application portfolio in collaboration with application owners and key stakeholders.
  • Gather application-related information (e.g., cost data) as input for analysis leveraging standard methods such as CBAM.
  • Maintain the enterprise architecture repository—including the architecture decision record (ADR) repository with clear compliance levels (mandatory versus recommendation)—as a single source of truth for all architecture artefacts, models, and decisions, to prevent decision drift.
  • Validate architectural recommendations with senior business and IT management.
  • Manage the Architecture Vision Document and contribute to the development of an enterprise‑wide IT roadmap encompassing current and future initiatives, projects, and programs, including impacts and dependencies.
  • Ensure alignment and integration of architecture processes with other IT management processes such as Project Portfolio Management and IT Service Management.
  • Perform Initiative Architecture Alignment Assessments as a governance gate at initiative kick-off and key delivery milestones, producing go/no-go/conditional recommendations to ensure projects and products align to the enterprise architecture vision, principles, and standards.
  • Conduct periodic Architecture Compliance Reviews during initiative delivery to verify continued adherence to architecture standards; escalate deviations to the ARB for exception or waiver processing.
  • Help define, govern, and maintain enterprise data architecture standards—including data modelling conventions, data integration patterns, and data governance principles—and assess initiative-level data designs against these standards.
  • Propose a realistic roadmap with the architectural points that need to increase in maturity.

Must Have Skills

  • At least 10 years of experience in an Enterprise Architecture role.
  • Proven experience facilitating ARB sessions and producing decision packs with traceability.
  • Strong autonomy and initiative, with the ability to engage effectively with stakeholders at all organisational levels.
  • Solid understanding of IT processes and methodologies, with practical experience using industry standards such as ITIL, TOGAF, ArchiMate, Domain‑Driven Design, and others.
  • Experience with cloud‑native architecture patterns and platform governance (guardrails, onboarding criteria, reference architecture adoption).
  • Familiarity with microservices and event‑driven architecture approaches.
  • Knowledge of Gartner architecture frameworks (e.g., TIME for Application Portfolio Management).
  • Experience working with modeling tools such as Sparx Enterprise Architect, SAP LeanIX or equivalent alternatives.
  • Ability to advocate and promote the adoption of reference architectures across teams.
  • Collaborative mindset, pragmatism, and ability to co-construct. 
  • Ability to act as a link between different stakeholders: Business, IT, Architecture, and Infrastructure teams.
  • Fluency in English is mandatory for documentation, supplier interactions, and meetings.

Nice to have

  • Knowledge of French, Dutch, or German is a plus (for collaborating with team members).
  • Experience in merger or acquisition contexts and the associated transformation journeys is considered a plus.
  • Hands‑on experience designing and delivering IT solutions in an agile environment is an asset.
  • Knowledge and experience of/in the Energy and Utilities sector is a plus.
  • Demonstrates results-oriented mindset.
  • Team‑oriented mindset, strong collaboration skills, and excellent presentation abilities.
