Key Responsibilities

Enterprise Architecture Ownership

- Act as the programme's Enterprise Architect, owning application, infrastructure and cloud, data, and business architecture as a single, coherent view, and working closely with the Security Lead so security architecture aligns with that same view.

- Own the cloud target architecture and application architecture across Azure and AWS, ensuring designs are consistent, integrated, and traceable to customer requirements.

- Own the technical outcome of the engagement, working alongside the Project Delivery Lead, who holds ultimate accountability for the programme overall.

- Ensure every architecture decision and design artefact reflects the customer's business needs, policies, and procedures before it proceeds to build.

- Own the end-to-end migration roadmap, ensuring assessment, planning, design, migration, testing, and transition activities remain aligned with programme objectives.

- Provide technical leadership and strategic direction across all migration workstreams, ensuring consistent decision-making and architectural alignment.

- Act as the final technical escalation point for architecture, migration, and implementation-related issues and decisions.

- Ensure alignment between architecture strategy, programme priorities, and business outcomes throughout the migration lifecycle.

SDLC Approval Gate Ownership

- Own the passage of design and architecture documents for each migration wave or batch through the customer's SDLC approval gates, from submission to endorsement.

- Ensure design refinements raised at each gate effectively address customer feedback before resubmission, avoiding repeat approval cycles.

- Maintain a structured approach to architecture governance, ensuring artefacts are complete, accurate, and submitted on schedule.

- Drive the closure of technical actions required to achieve approvals within agreed programme timelines.

Continuous Improvement, Reuse and Standardisation

- Develop the process for capturing migration patterns and automation built during delivery, ensuring they are documented and available for reuse across later migration waves.

- Continuously drive efficiencies in the SDLC process, delivery standardisation, and the use of AI and tooling, reducing rework and cycle time across the programme.

- Review completed migration waves for reusable patterns and feed improvements back into the assessment, design, and delivery methodology.

- Promote and establish migration standards and best practices across all delivery teams.

Migration Approach and Tooling / AI Alignment

- Own full alignment of the migration approach, including application of the 7Rs framework and tooling/AI usage, with the customer's business needs, policies, and procedures.

- Propose AI and tooling capabilities to the customer and work closely with them through their approval process, drawing on the AI/Tools Architect within the team to prepare the technical case.

- Govern the future-proofing of tool and platform choices, balancing innovation against the customer's risk appetite and standards.

- Ensure migration planning, wave sequencing, and transformation activities remain aligned to technical and business objectives.

- Evaluate and recommend migration accelerators, automation opportunities, and technology innovations that increase programme efficiency and reduce delivery risk.

Customer Engagement and Relationship Ownership

- Build and maintain close, trusted relationships with the customer's architects, architecture leadership, executive stakeholders, business leaders, and technical teams.

- Serve as the senior day-to-day customer-facing representative for the migration programme.

- Work directly and continuously with customer business and technology stakeholders to validate architecture direction and resolve technical concerns.

- Lead customer workshops, migration planning sessions, executive briefings, technical governance reviews, and steering committee updates.

- Represent Unisys architecture positions in customer forums, working sessions, and technical reviews with clarity and technical credibility.

- Manage technical stakeholder expectations and maintain alignment between customer objectives, programme priorities, and delivery outcomes.

- Proactively identify, communicate, and resolve customer concerns, risks, and dependencies that may affect migration success.

- Work closely with customer programme leadership to establish migration priorities,



sequencing, and roadmap decisions.

Architecture Review Board and Governance Alignment

- Own alignment with the customer's Architecture Review Board (ARB) and architecture function for every design and migration decision requiring endorsement.

- Prepare and present architecture artefacts, options papers, migration strategies, and design decisions to the ARB.

- Carry endorsed decisions back into delivery and ensure implementation aligns with approved architecture.

- Maintain architecture governance discipline across the programme, including design authority, standards compliance, and decision traceability.

- Ensure all solution decisions remain compliant with customer policies, standards, security requirements, and governance processes.

Team Leadership

- Provide overall leadership and direction to the migration programme team, including architects, migration specialists, engineers, analysts, and partner resources.

- Act as team lead for all architects engaged in assessment, strategy, and design functions, including the AI/Tools Architect, setting technical direction and reviewing their output for quality, consistency, and customer alignment.

- Establish team priorities, work allocation, and technical delivery objectives across migration waves and workstreams.

- Lead technical risk, issue, and dependency management activities across the programme.

- Drive collaboration across customer, partner, and Unisys teams to ensure successful programme execution.

- Work closely with the Project Delivery Lead and Security Lead to ensure programme objectives, delivery priorities, and technical outcomes remain aligned.

- Mentor and develop architects and technical specialists, building capability across application, infrastructure, cloud, data, and business architecture disciplines.

- Foster a culture of accountability, innovation, collaboration, and continuous improvement.

Programme Leadership and Delivery Alignment

- Lead the technical planning and execution of the migration programme, ensuring alignment between architecture strategy and delivery execution.

- Develop and maintain migration roadmaps, migration wave plans, transition strategies, and technical delivery plans.

- Identify programme risks, issues, assumptions, and dependencies and work with customer and Unisys stakeholders to drive timely resolution.

- Provide regular technical status reporting, risk assessments, and programme updates to customer and Unisys leadership.

- Ensure migration decisions consider business value, cost, schedule, security, operational supportability, and long-term sustainability.

- Support programme governance activities through technical oversight and leadership across all migration phases.

- Ensure architecture, migration, and implementation teams operate cohesively towards agreed programme objectives and milestones.

Cost Awareness and FinOps Input

- Design with cost effectiveness in mind, evaluating architecture options against cost, performance, and sustainability trade-offs.

- Provide architecture input into the customer's FinOps function.

- Identify opportunities to reduce recurring cloud costs through right-sizing, architecture simplification, and consumption-based design choices.

- Support business case development and migration planning activities with accurate cost modelling assumptions and architecture guidance.

Innovation and Sustainability

- Drive innovation in migration tooling, automation, and AI-assisted delivery methods.

- Own the sustainability of the application, delivery, and support model, ensuring the target architecture remains supportable and extensible beyond go-live.

- Evaluate emerging Azure and AWS capabilities for fit against the customer's target architecture and long-term technology direction.
