ERP Ecosystem Architect

PERMENANT - LONDON

About the Context

The D365 HERO Programme is a multi-year global transformation delivering a harmonised Microsoft Dynamics 365 Finance & Operations solution across all regions, replacing regional ERPs and enabling a standardised global core model. The programme manages deep integration with the wider ecosystem including POS, WMS, EDI, middleware, retail, and enterprise systems.

The D365 Ecosystem Technical Architect plays a critical role within the Solution Architecture team in ensuring technical integrity and scalability excellence across this landscape.

Your role @ Chanel

As the D365 Ecosystem Architect, you act as the technical solution authority across a complex enterprise environment. You bring solution clarity by driving alignment across various teams with different priorities, ways of working to achieve solution standardisation. You sit at the intersection of business strategy, solution design, and delivery execution, shaping how D365 integrates and evolves globally. You work closely with integration architects, solution architects, developers, engineering/product teams and cross functional teams. This role demands structured thinking, clear communication, and the ability to simplify complexity within a fast-paced transformation.

The impact you can create at Chanel

1. End-to-End Technical Solution Architecture Ownership

• Coordinate end-to-end architecture across parallel workstreams/programmes-aligning scope boundaries, ownership, dependencies, and sequencing-to prevent divergence/duplicated solutions and avoid solution gaps in end-to-end processes.
• Create and own the End 2 End multi system technical architecture blueprint for D365 that connects with Power Platform, Azure services, Fabric, key Tier-1 systems and any regional applications.
• Ensure cohesive, scalable, and secure end-to-end technical solutions across regions.
• Shape and evolve the long-term architecture roadmap.

2. Technical Leadership & Delivery Oversight

• Assess end-to-end solution impact of changes and ensure they are reflected in architecture decisions, technical specifications, and delivery plans across teams.
• Enforce architectural standards, extensibility models, and event-driven patterns.
• Review and approve specifications, customisations, and integrations that impact end to end process flows across multiple systems.
• Facilitate cross-system design alignment with solution owners (POS, WMS, EDI, middleware, data platform, identity/security), ensuring decisions are understood, documented, and governable.
• Support environment and build strategy by working closely with the Product Team Technical Manager.

3. Quality Assurance & Development Governance

• Ensure development follows Microsoft-recommended patterns (extensions, event-driven design) and solution architecture guardrails.

4. Integration & Data Architecture Support

• Support integration architects to enforce integration patterns, API design, messaging, and middleware.
• Oversee data migration standards and contribute to data governance strategy.
• Collaborate with Fabric and data teams on reporting requirements, lineage, quality, and master data.

5. Continuous Improvement & Innovation

• Stay abreast of Microsoft’s D365 and Power Platform roadmap(Aligning with internal Chanel Power Platform Roadmap).
• Recommend enhancements and optimisation opportunities and contribute to the solution roadmap.

6. Solution Risk & Governance

• Maintain the End-to-End solution risk register and mitigation plans.
• Ensure consistent architectural guardrails across global teams and partners.
• Uphold non-functional requirements (performance, resilience, security).

7. Typical Deliverables

• Core solution architecture artefacts for the D365 ecosystem (target-state views, integration maps, NFRs, infrastructure/infosec and Azure service considerations).
• Confirm the end-to-end scope of technical specifications (internal and partner) across D365, integrations, Power Platform, and Tier-1 systems, working with stakeholders and system owners to align responsibilities, interfaces, and delivery expectations.
• End to End solution risk register and mitigation plans
• Contributions to solution roadmap and multi-instance strategy

You are energized by

• Working within a complex landscapeglobal systems, Multiple ERP (D365,SAP,AX), Multiple POS (Oracle, Cegid, Dynamics, TTPOS), WMS (D365,Manhattan), BI systems.
• Solving integration and data challenges across a high-volume, multi-region landscape.
• Bringing clarity and translating complex needs into simple, actionable technical designs.
• Championing standardisation, guiding teams on when to extend vs. use out-of-the-box capabilities.
• Collaborating with architects, infrastructure teams, product owners, developers, and enterprise teams to drive aligned outcomes.
• Enforcing architectural guardrails that keep the global solution consistent and resilient and elevating technical capability across partners.
• Working in a fast-paced transformation where architectural decisions have real business impact. Turning complex problems into well-structured solutions and clear documentation.
• Keeping ahead of Microsoft’s roadmap and identifying opportunities to innovate and optimise.

What you will bring

Experience

• 10 years in ERP as a Solution/Technical Architect or Technical/Functional Lead - preferrable in D365 F&O or AX 2012 but not mandatory.
• Proven experience owning end-to-end solution scope across a complex, high-integration, enterprise-scale multi-system ecosystem, aligning parallel workstreams on scope boundaries, system ownership, dependencies, and sequencing across teams and divisions.
• Experience with modernisation initiatives: cloud migration, modularisation, API-driven architecture.

Cross-Functional Soft Skills

• Strong stakeholder management across divisions and regions: builds trust, listens actively, and adapts communication style to different audiences.
• Facilitation and alignment: leads workshops to converge on scope, ownership boundaries, and architectural decisions across parallel workstreams.
• Influence without authority: able to challenge constructively, navigate differing priorities, and gain commitment to standardisation and global guardrails.
• Conflict resolution and negotiation: mediates trade-offs (time/cost/risk/complexity) and drives timely decisions when teams disagree.
• Comfortable operating in ambiguity: creates clarity from incomplete information and maintains momentum in a fast-paced programme environment.
• Communication: produces clear decision papers, options, and recommendations that enable fast, informed governance.
• Coaching and collaboration mindset: elevates architecture quality across internal teams and partners through feedback, guidance, and pragmatic guardrails.
• Skilled at documenting architecture artefacts for business and technical audiences.

Architecture Skills

• Application architecture: DDD, modular monoliths, microservices, API gateways.
• Non-functional architecture: scalability, resilience, observability, DR, SLAs.
• Technical architecture: reference models, interim and target-state design, roadmaps.
• DevOps : manage architecture deliverables, decisions, and cross-system dependencies as Azure DevOps work items and keep backlogs visible and current across the teams.

(useful, not mandatory)

• Enterprise frameworks: TOGAF/Zachman/ArchiMate
• Integration architecture: APIs, events, microservices, messaging, security boundaries.
• Data architecture familiarity: Fabric, data governance, modelling, quality & lineage.
• Security-by-design: IAM, encryption, threat modelling, compliance.
• Cloud architecture familiarity: Azure, identity, security, cost optimisation.
