M&A Transformation Architect: End-to-End Integration in City of Westminster

As an M&A Integration & Separation Architect, you will play a pivotal role in shaping and delivering complex transformation programmes driven by mergers, acquisitions, divestitures, and carve-outs. You will operate at the intersection of strategy, architecture, and execution, translating deal intent into robust, executable blueprints that enable successful business outcomes. You will own the definition of end-to-end integration and separation architectures, including Target Operating Models (TOM), transition states, and the technical and operational roadmap required to achieve them.

Working across applications, infrastructure, data, identity, and business processes, you will ensure that solutions are not only strategically aligned but also feasible, scalable, and deliverable within the constraints of the deal. You will be engaged across the full M&A lifecycle - from pre-deal feasibility and technology due diligence, through Day-1 readiness and TSA design, to post-close stabilisation and value realisation. You will collaborate closely with client stakeholders, functional leads, and Infosys delivery teams to ensure seamless execution, while maintaining a clear focus on business continuity, risk mitigation, and value capture.

This role requires a blend of strategic thinking, deep architecture expertise, and hands-on delivery leadership, as well as the ability to operate effectively in ambiguous, high-pressure environments where timelines are fixed and outcomes are critical.

• Architecture Leadership & Design
  • Define and own the end-to-end integration or separation architecture, including Target Operating Model, transition architectures, and phased delivery roadmap.
  • Translate deal thesis and business objectives into practical, executable architecture designs across applications, infrastructure, data, and processes.
  • Establish guiding principles, standards, and architectural guardrails to drive consistency across complex programmes.
• M&A Lifecycle Delivery
  • Lead pre-deal and pre-close activities, including technology due diligence, feasibility assessments, and identification of critical Day-1 risks and dependencies.
  • Support post-close execution, including stabilisation, TSA exit acceleration, and transition to target state.
• Feasibility & Risk Management
  • Assess feasibility of integration or separation plans across enterprise applications and platforms, infrastructure and cloud environments, and data and analytics architecture.
  • Identify key risks, constraints, and dependencies, and define pragmatic mitigation strategies aligned to deal timelines.
• Cross-Functional Orchestration
  • Work closely with functional workstream leads (IT, Finance, HR, Operations) to ensure alignment between architecture and business execution.
  • Act as a bridge between strategy and delivery teams, ensuring that designs are effectively implemented across Infosys and client delivery teams.
  • Support Integration Management Office (IMO) in aligning architecture decisions with programme governance and delivery milestones.
• Stakeholder Engagement & Advisory
  • Engage with senior client stakeholders to shape decisions, challenge assumptions, and provide expert guidance.
  • Facilitate workshops to define architecture direction, validate assumptions, and align cross-functional teams.
  • Articulate complex technical concepts in a clear and compelling way to both technical and non-technical audiences.
• Practice Development & Thought Leadership
  • Contribute to the development of Infosys Consulting's M&A propositions, methodologies, and assets.
  • Stay at the forefront of industry trends, including cloud transformation, AI-enabled operations, and digital platform integration in M&A contexts.
  • Coach and support junior team members, helping to build our growing M&A architecture capability.

Our M&A practice is at the forefront of this ambition. We partner with corporate and private equity clients across the full deal lifecycle - from technology due diligence and pre-sign feasibility, through Day-1 readiness and Transaction Service Agreement (TSA) design, to post-close integration, separation, and value realisation. We act as an execution confidence partner, ensuring that deal intent is translated into practical, deliverable outcomes that maximise value and minimise risk.

We bring a distinctive combination of advisory, architecture, and delivery orchestration, supported by Infosys' global delivery capability. Our teams work across applications, infrastructure, data, and business processes to enable seamless integration or separation, while maintaining business continuity and accelerating synergy realisation. We also leverage emerging technologies, automation, and AI-enabled insights to enhance decision-making and drive efficiency throughout the deal lifecycle.

Joining our team means being part of a growing and differentiated M&A capability where you will work alongside experienced practitioners, contribute to building new propositions, and help shape how organisations execute some of their most critical and high-stakes transformations.

• Significant experience (6+ years) in M&A integration, separation, or large-scale transformation programmes.
• Proven track record of defining and delivering end-to-end architecture in complex, multi-workstream environments.
• Strong experience across multiple architecture domains: Enterprise applications, Cloud and infrastructure, Data and analytics, Identity and access management.

• Strong consulting skillset with the ability to operate across strategy, design, and execution phases.
• Experience working in fast-paced, high-pressure deal environments, managing ambiguity and fixed timelines.
