Enterprise Architect

Role: Enterprise Architect

Location: Brussels Belgium

Duration: 6+ Months

Languages:  French and Dutch English

Work Mode: Hybrid

Job Description:  

As an Enterprise Architect, you will:

· Start immediately and take ownership of turning the approved operating model into concrete working practices, with a prioritized implementation backlog, milestones, dependencies, risks, decision points and suitable pilots. The role requires a pragmatic architect who drives execution and delivers visible results quickly.

· Lead the definition and continuous improvement of the architecture governance framework, including principles, standards, policies, reference architectures and golden scenarios, within a clear ARB decision workflow covering decision packs, traceability and escalation paths.

· Operationalize the federated Target Operating Model by clarifying the mandates, interactions, decision rights, handovers and escalation paths of Group and Local Enterprise Architects, Domain Architects, Technical Architects and Solution Architects.

· Provide a clear architecture vision and bring Group, local, business, product, delivery, engineering, security, data and infrastructure stakeholders together around shared priorities, practical decisions and reusable solutions.

· Establish or refine Group and Local Architecture Review Board practices, including scope, participation, quorum, agenda, inputs, outputs and decision recording, and facilitate the first governance sessions.

· Implement objective review triggers, delegated decision routing, Architecture Decision Records, waiver and exception management, compliance levels and an urgent fast-track route.

· Ensure alignment with client’s Digital Platform by translating platform guardrails into consumable guidance for local delivery teams.

· Embed Architecture early into portfolio and funding, demand intake, project and product delivery, application lifecycle, security and risk, data and integration, and technology or vendor selection.

· Introduce proportionate architecture involvement based on criticality, complexity, risk, deviation and cross-entity impact, without creating a shadow PMO or unnecessary approval layer.

· Establish the minimum viable architecture artefact set, with clear ownership, approval routes, versioning, review triggers and retirement rules.

· Coach architecture roles, establish an Architecture Community and focused working groups, and transfer knowledge so that internal stakeholders can operate the model independently.

· Define focused KPIs covering adoption, decision effectiveness, delivery enablement, reuse, compliance, risk and stakeholder value.

· Create momentum and cohesion across teams: facilitate decisions, remove ambiguity, constructive challenge when needed, and ensure that agreed actions are followed through to implementation.

Requirements:

Candidates must meet the following requirements:

· At least 10 years of experience in an Enterprise Architecture role.

· Available to start immediately and able to work autonomously, create structure in ambiguity and maintain momentum until decisions are implemented.

· Proven experience in federated, multi-entity or similarly complex architecture governance environments. 

· Proven experience facilitating ARB sessions and producing decision-ready packs with traceability. 

· Hands-on experience implementing delegated decision rights, ADRs, waivers, compliance reviews and architecture service models. 

· Strong strategic thinking combined with a pragmatic, hands-on and results-oriented mindset. 

· Strong facilitation and stakeholder-management skills, with the ability to align senior management, architects, business, product, engineering, infrastructure and delivery teams. 

· Ability to articulate a compelling vision, build trust, create shared ownership and bring people together around difficult trade-offs. 

· Solid knowledge of IT processes and recognized approaches such as ITIL, TOGAF, ArchiMate and Domain-Driven Design. 

· 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.

· Fluency in English is mandatory for documentation, supplier interactions, and meetings. Knowledge of French, Dutch, or German is a plus, as you will collaborate with team members speaking these languages.

Ideal profile: This is not primarily a Solution Architect role. Target a 10+ year Senior/Lead Enterprise Architect who has personally established or transformed architecture governance in federated/multi-entity organisations, facilitated ARBs, and implemented ADRs, delegated decision rights, waivers/exceptions and compliance processes. The person also needs to be execution-focused rather than purely strategic.
