Principal Cloud Architect

The Role

The Evolve programme is accelerating Euroclear’s adoption of public cloud by establishing secure, resilient and scalable foundations, architecture standards and reusable implementation patterns. It brings together architecture, engineering, security, operations and migration stakeholders to enable workloads to move to and operate effectively on Azure in line with Euroclear’s business, risk and regulatory requirements.

As Principal Cloud Architect, you will act as a senior architecture leader for cloud adoption. You will set architecture direction across a broad, cross-organisational scope; help mature the Cloud Solution Design Authority into an effective and sustainable decision-making body; steer cloud foundation priorities; govern architecture artefacts and reference implementations; and provide pragmatic guidance to workload teams.

The role combines strategic architecture leadership, hands-on delivery support and cross-functional decision-making. A key outcome is to expand Euroclear’s cloud presence responsibly by turning cloud strategy and principles into actionable standards, deployable patterns and sound workload decisions.

Key Responsibilities

Cloud Solution Design Authority

• Mature the Cloud Solution Design Authority by clarifying its mandate, decision rights, intake process, governance, cadence, quality criteria and follow-up of architecture decisions.

• Establish a sustainable operating rhythm that enables timely, traceable and risk-informed decisions.

• Facilitate complex architecture discussions, document outcomes and ensure that decisions, conditions and actions have clear owners.

• Improve the quality and consistency of architecture submissions by providing guidance, templates and early engagement.

Cloud Foundations and Roadmap

• Refine, prioritise and maintain the cloud foundation roadmap across identity, connectivity, security, governance, management, operations and automation.

• Balance migration demand, risk reduction, platform scalability, technical debt and delivery capacity when setting priorities.

• Identify cross-platform dependencies and sequence foundation capabilities so that workload teams can adopt cloud safely and efficiently.

• Advise programme and technology leadership on architecture choices, investment priorities and delivery trade-offs.

Architecture Direction and Artefacts

• Develop, maintain and govern cloud architecture principles, standards, target-state designs, roadmaps and architecture decision records.

• Translate enterprise strategy, regulatory expectations and delivery needs into clear architecture direction.

• Ensure cloud architecture remains aligned with enterprise, security, data, resilience and technology standards.

• Maintain traceability between strategic objectives, architecture decisions, implementation guidance and delivery outcomes.

Reference Implementations and Reusable Patterns

• Prioritise reusable cloud patterns and reference implementations based on workload demand, risk reduction and strategic value.

• Guide their delivery so that approved patterns are deployable, testable, automated and consumable by workload teams.

• Translate architecture into infrastructure-as-code accelerators, policy-driven guardrails and reusable platform services.

• Promote standardisation and governed self-service while limiting manual fulfilment and one-off solutions to justified exceptions.

Workload Assessment and Migration Guidance

• Support migration teams and workload owners in assessing application architecture, dependencies, data, security, resilience, operability, compatibility and migration readiness.

• Recommend appropriate migration or modernisation strategies based on business value, criticality, compliance, lifecycle impact and technical feasibility.

• Help teams select the most appropriate service model, considering SaaS, PaaS, containers and IaaS without assuming that one model is universally optimal.

• Identify architecture gaps and convert assessment findings into actionable remediation, sequencing and decision points.

Cloud Footprint and Regional Architecture

• Shape the expansion of Euroclear’s cloud footprint, including new-region adoption, regional operating models and multi-region approaches.

• Assess implications for foundations, connectivity, identity, security, data residency, resilience, operations, support and cost.

• Define architecture guidance for workload placement and regional deployment.

• Ensure exceptions to approved regions or patterns have documented rationale, risk assessment, ownership and approval.

Sustainability and Net-Zero Assessment

• Assess the cloud implications of sustainability and Net-Zero-related decisions.

• Evaluate architecture trade-offs involving region selection, service choices, resource efficiency, carbon considerations, cost, resilience and performance.

• Promote efficient use of managed and cloud-native services where they provide measurable value and acceptable risk.

• Ensure sustainability considerations are incorporated into architecture decisions and roadmaps without compromising security, regulation or service quality.

Architecture Assurance

• Review solution designs and assess alignment with approved principles, standards, target architectures and reference patterns.

• Identify material risks, gaps and deviations, and provide clear recommendations to delivery teams and decision-makers.

• Ensure exceptions have an explicit rationale, accountable owner, remediation action and expiry or review date.

• Track recurring deviations and use them to improve standards, patterns, platform capabilities and governance.

Stakeholder Alignment and Leadership

• Work closely with Enterprise Architecture, Cloud Engineering, CISO, Production, Business Resilience, migration teams, programme leadership and workload owners.

• Resolve architectural dependencies and accelerate decisions across organisational boundaries.

• Influence senior business and IT stakeholders by making complex trade-offs clear and decision-ready.

• Challenge constructively and drive outcomes without relying solely on formal authority.

Architecture Community and Knowledge Transfer

• Coach and mentor architects and engineers working on cloud initiatives.

• Strengthen the architecture community through knowledge sharing, reviews, reusable guidance and lessons learned.

• Ensure cloud standards, patterns and decision processes are understood and applied consistently.

• Promote pragmatic, collaborative and outcome-focused ways of working across architecture and delivery teams.
