Mission

Lead architecture for enterprise-wide, high-impact I&O initiatives that cut across platforms, regions, and organizations. Ensure coordinated execution, proactive risk management, and timely executive decision support across the full lifecycle of transformation programs.

Scope of Responsibility

This role serves as the architectural and integration authority across the following program types:

• Regional and Country Expansion — architecture for net-new footprint build-out and onboarding
• Mergers, Acquisitions & Divestitures (M&A/D) — integration and separation strategies from LOI through Day 100+
• Internal and External Audits — IT allocation exercises, evidence architecture, and audit-readiness frameworks
• Regulatory & Remediation Programs — architecture supporting compliance mandates and remediation roadmaps
• Enterprise Operating Model Changes — structural and process changes affecting I&O delivery models
• Large-Scale Infrastructure Transformations — application segmentation, data center migrations, cloud transitions

Key Responsibilities

Foundational I&O Architecture & Program Design

• Translate complex business and regulatory requirements into actionable, integrated infrastructure architectures
• Establish integration and separation blueprints for M&A and divestiture programs
• Drive consistency and reuse of architectural patterns across programs and regions

Program Execution & Coordination

• Develop and govern Day 0, Day 1, and Day 100 execution plans for major transformation programs
• Coordinate across platform teams, regional leads, and business stakeholders to ensure alignment and delivery
• Identify and manage interdependencies across concurrent initiatives to prevent conflicts and gaps
• Drive structured program governance, including decision logs, RAID tracking, and milestone accountability

Risk, Cost & Timeline Management

• Build and maintain risk, cost, and timeline scenario models for executive consumption
• Surface emerging risks early and facilitate mitigation planning before escalation is required
• Develop trade-off analyses for architectural and investment decisions with clear recommendation framing

Executive Engagement & Communication

• Author executive decision and trade-off memos for I&O leadership and C-suite stakeholders
• Translate technical complexity into clear, structured briefings appropriate for non-technical audiences
• Serve as a trusted advisor to I&O executives on program posture, risk, and strategic direction

Standards, Practices & Audit Readiness

• Embed audit-readiness into architecture and program design from the outset
• Define and maintain integration and transformation standards, playbooks, and reference architectures
• Support internal and external audit exercises through structured documentation and evidence frameworks

Core Outputs

• Foundational I&O-Level Architectures — the structural blueprint for all major I&O programs
• Integration & Separation Strategies — guide M&A and divestiture execution at the infrastructure layer
• Day 0 / Day 1 / Day 100 Plans — sequenced, risk-managed execution across transition milestones
• Risk, Cost & Timeline Scenarios — enable informed executive investment and scheduling decisions
• Executive Decision & Trade-off Memos — drive timely, well-framed decisions at the leadership level

What Success Looks Like

• Predictable M&A Integrations — programs deliver against Day 1 and Day 100 commitments with no critical surprises; architectural decisions are made early and documented
• Audit Readiness by Design — I&O architecture and documentation consistently satisfy internal and external audit requirements without reactive scrambling
• Fewer Last-Minute Escalations — risks are identified and escalated in a structured, timely manner; executive surprises are rare and bounded
• Clear Executive Visibility — I&O leadership has consistent, accurate visibility into prog
