Global Head of Enterprise Infrastructure & Architecture

We are looking for a Global Head of Enterprise Infrastructure & Architecture to lead the strategy, design and operation of M+C Saatchi Group’s global infrastructure, enterprise architecture, data platform foundations and AI-ready technology capability.

This role sits at the core of our technology ecosystem — responsible for the platforms, integrations, automation and standards that enable the Group to operate securely, reliably and at scale.

Reporting to the Global Chief Information Officer, you will lead the Infrastructure & Architecture function and work closely with Information Security, Service Delivery, Data, AI Operations and business stakeholders to ensure technology services are aligned to enterprise standards and business priorities.

Based in London, with a hybrid working pattern, the role operates across a global network of teams.

ABOUT THE ROLE

As M+C Saatchi Group continues to simplify, modernise and harmonise its global technology estate, we require a senior technology leader to own the infrastructure and architecture foundations that support secure, scalable and effective operations across the Group.

This is a strategic leadership role spanning cloud platforms, network services, identity, collaboration technologies, enterprise architecture, integration, data platform enablement and AI-ready foundations. It is distinct from service desk operations or business-led AI adoption — instead focused on how the core technology environment is designed, governed and scaled.

You will provide leadership across your areas of responsibility, ensuring projects and support services are delivered through consistent standards, robust governance and clear alignment with business strategy.

Success in this role will look like:

• A well-governed, scalable, enterprise infrastructure and architecture aligned to business strategy, security requirements and technology roadmaps

• Consistent standards across cloud, identity, networking, collaboration, integration, data and AI platform services

• Reduced technology complexity through consolidation, automation, lifecycle management and rationalisation

• Clear foundations for data harmonisation, reporting, analytics, automation and AI-enabled services

• A high-performing global team with clear ownership, accountability and delivery focus

WHAT YOU'LL DO:

• Define and own the global infrastructure and enterprise architecture strategy, roadmap and target-state ecosystem

• Lead the design, operation and continuous improvement of core technology platforms including cloud infrastructure, identity services, networking, collaboration technologies, storage, endpoint management and enterprise platforms

• Establish and govern enterprise architecture principles, reference architectures, design standards and technology roadmaps across infrastructure, applications, data, integration and AI platform services

• Provide technical leadership and architectural assurance for infrastructure, platform, data and AI-related transformation initiatives before production deployment

• Drive data platform simplification, consolidation and harmonisation, ensuring data services are resilient, secure, scalable and appropriately governed

• Define and govern the Group's enterprise integration architecture, middleware platforms and iPaaS capabilities, ensuring seamless interoperability between applications, data platforms, AI services, cloud technologies and external partner ecosystems

• Define the infrastructure, platform and architectural standards required to support enterprise AI, automation, agentic workflows, innovation sandboxes and emerging technology initiatives

• Drive automation across infrastructure operations, provisioning, configuration management, monitoring and service delivery processes

• Ensure operational resilience through robust monitoring, disaster recovery, business continuity planning and incident response capabilities

• Own infrastructure capacity planning, performance management, availability management and service optimisation activities

• Lead identity, access management and platform security initiatives in partnership with the Information Security function

• Oversee vendor relationships, managed service providers, strategic technology partners and infrastructure-related procurement activities

• Lead and develop a global team of infrastructure engineers, support analysts and platform specialists

• Partner with Service Delivery teams to ensure new and changed services transition cleanly into operational support

• Provide regular reporting, strategic recommendations and technology roadmaps to the Global CIO and senior stakeholders

ABOUT YOU

You are an experienced technology leader who combines strong infrastructure expertise with a strategic understanding of enterprise architecture, data platforms, integration and AI-ready technology foundations.

You are comfortable operating at both strategic and operational levels, influencing senior stakeholders while remaining connected to the realities of technology delivery and service operation.

You thrive in complex global environments and enjoy leading teams through transformation, simplification, modernisation and continuous improvement.

You’ll bring with you (experience and qualifications):

• Significant experience leading enterprise infrastructure, cloud platforms and technology operations in a complex global organisation with hybrid technology environments

• Proven experience developing and implementing enterprise architecture strategies, governance models and technology standards

• Strong knowledge of Microsoft technologies, specifically M365 applications inc. Copilot, Entra, Intune, Defender and Azure cloud platforms

• Experience managing global networks, identity platforms, collaboration technologies and enterprise infrastructure systems and services i.e. ERP, CRM

• Experience delivering infrastructure transformation, consolidation, standardisation and lifecycle management programmes

• Strong knowledge of cloud-based data storage platforms, including file management structures/security and AI-ready platform foundations

• Experience designing and governing enterprise integration architectures, including middleware, iPaaS platforms, APIs, event-driven architectures and data exchange frameworks.

• Strong understanding of infrastructure security, risk management, compliance and resilience frameworks

• Experience leading geographically distributed technical teams and specialist engineering resources

• Experience managing technology vendors, managed service providers and strategic partnerships

• Strong financial management, budgeting and technology investment planning skills

• Excellent stakeholder management, leadership and communication capabilities

Additional desirable experience:

• Experience supporting AI-enabled platforms, agentic workflows, orchestration tools or innovation sandbox environments

• Experience supporting mergers, acquisitions, regional integrations or global organisational transformation

• Familiarity with ISO27001, NIST, Cyber Essentials Plus or related governance frameworks

• Experience implementing infrastructure automation, Infrastructure-as-Code or platform engineering practices

• Exposure to FinOps, cloud cost optimisation and technology portfolio rationalisation initiatives

• Experience within professional services, media, marketing, consulting or creative industries

WHAT YOU'LL GET:

APPLICATIONS CLOSE: Wednesday, 12th August 2026.

We will review candidates on a rolling-basis and reserve the right to close the job early should we receive a high volume of applications - early application is therefore encouraged.
