Working under the guidance of the Architecture Team at Organization, the Infrastructure Solution Architect collaborates with M&A leaders, business stakeholders, project teams, delivery partners, cybersecurity, operations, and technical specialists to assess infrastructure estates, define target-state architectures, develop separation and integration roadmaps, and support execution across on-premises platforms, cloud services, virtualization, identity, and networks.

Key Responsibilities

• Lead the architecture, planning, and execution of technology integration and separation activities for mergers, acquisitions, and divestitures, spanning cloud, Active Directory, identity, server, storage, network, end-user computing, and infrastructure services.
• Conduct technical due diligence and current-state assessments to identify integration requirements, operational risks, technology dependencies, TSA impacts, security considerations, and modernization opportunities.
• Define target-state infrastructure architectures, migration strategies, and transition roadmaps that align business objectives, technology standards, cybersecurity requirements, operational support models, and Day-1 readiness goals.
• Partner with application, infrastructure, cybersecurity, operations, and business stakeholders to manage cross-functional dependencies, resolve technical issues, and ensure successful cutover, migration, and transition-to-support activities.
• Provide technical leadership and architecture governance throughout the integration lifecycle, ensuring solutions are secure, scalable, resilient, supportable, and aligned with enterprise standards and long-term strategic objectives.
• Guide implementation partners and technical teams, resolve cross-domain design issues, and ensure delivered solution remains consistent with approved architecture.
• Present new technologies, exceptions, and significant architecture decisions to relevant Organization governance forums, including the Architecture Review Board (ARB) and Technology Working Group (TWG).
• Support business continuity, disaster recovery, security testing, performance validation, and operational acceptance for migrated and integrated services.
• Prepare architecture artifacts, compliance checklists, options analyses, cost estimates (C5, C3, and C1), decision records, and executive presentations required for governance and investment decisions.
• Ensure handover to operations (TTO), including support models, monitoring, documentation, asset records, knowledge transfer, and closure of transition risks and technical debt.

Required Qualifications

• Bachelor’s degree in Computer Science, Engineering, Information Systems, or a related field, or equivalent practical experience.

• Proven experience supporting mergers, acquisitions, divestitures, or other large-scale business integrations, including discovery, due diligence, Day 1 planning, transition services, migration, and operational handover.
• Hands-on architecture experience across on-premises infrastructure, public cloud, virtualization, identity and access management, Active Directory, and enterprise networking.
• Demonstrated ability to create migration roadmaps, architecture designs, cost estimates, risk assessments, and executive-ready recommendations for complex initiatives.
• Strong stakeholder management, facilitation, written communication, and technical leadership skills in large enterprise environments.

Technical Competencies

• M&A infrastructure due diligence, integration planning, separation planning, and transition service agreement exit
• Data centre, compute, storage, backup, disaster recovery, and infrastructure operations architecture
• Virtualization platforms and lift-and-shift migration approaches, including VMware and Hyper-V
• Cloud architecture and migration across Microsoft Azure and AWS, including hybrid connectivity and landing-zone alignment
• Active Directory, Entra ID, identity federation, directory synchronization, DNS, DHCP, and privileged access
• Enterprise network architecture, including WAN/LAN, routing, segmentation, firewalls, VPN, cloud networking, and site connectivity
• Infrastructure security, vulnerability remediation, resilience, capacity, monitoring, and operational readiness
• Migration planning, dependency mapping, cutover orchestration, rollback, testing, and stabilization
• Architecture modelling, documentation, and portfolio tools such as LeanIX

Preferred Qualifications

• TOGAF, Microsoft Azure, AWS, VMware, Cisco, or other relevant architecture and infrastructure certifications.
• Experience integrating acquired businesses into a common enterprise operating model and technology environment.
• Experience in regulated industries such as energy, utilities, finance, or healthcare; oil and gas industry experience is an asset.
