Enterprise Architect (Lead Cloud Applications Migration Architect)

What success looks like in this role: The Lead Cloud Migration Architect is the technical leader and Enterprise Architect for the application migration and modernisation programme delivered across Azure and AWS cloud platforms. The role leads application assessment, migration planning, and architecture activities, defining migration strategies, migration waves, target state architectures, and transformation roadmaps that support the customer's cloud adoption objectives.

As the senior technical authority for the programme, the Lead Cloud Migration Architect provides leadership to the migration team and serves as the primary technical point of contact for the customer. The role works closely with customer stakeholders, architects, project teams, and Unisys leadership to ensure migration decisions are aligned with business objectives, architecture standards, security requirements, delivery timelines, and commercial outcomes.

The role owns the technical outcome of the programme, leading architectural decision making from assessment through to implementation and ensuring migration designs, plans, and deliverables are technically sound, aligned with customer requirements, and capable of delivering a successful and sustainable cloud transformation. The Lead Cloud Migration Architect is accountable for leading application discovery and assessment activities, defining migration approaches, prioritisation and wave planning, and guiding applications through their migration journey.

The role is responsible for taking design and architecture artefacts for each migration wave through the customer's SDLC approval gates, ensuring feedback is addressed and approvals are secured in a timely manner. The role represents Unisys within the customer's Architecture Review Board (ARB) and wider architecture function, providing technical leadership across assessment, strategy, design, and migration planning activities.

Working closely with the Delivery Lead, Security Lead, customer stakeholders, technology partners, and the AI/Tools Architect, the Lead Cloud Migration Architect ensures migration decisions are technically sound, aligned with customer policy, and support the successful delivery of the overall programme. As the senior technical leader for the engagement, the Lead Cloud Migration Architect provides leadership, direction, and coordination across assessment, architecture, migration, implementation, and transition activities.

The role acts as the primary technical representative for Unisys, working closely with customer executives, business stakeholders, programme leadership, and delivery teams to ensure successful programme outcomes. The role is responsible for maintaining alignment between technical strategy, migration delivery, business objectives, and governance requirements while proactively managing technical risks, dependencies, and stakeholder expectations throughout the programme lifecycle.

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.
