Specialist System Engineering (Cloud Migration Lead)

The Cloud Migration Readiness Lead supports large-scale AWS Outposts, IT Private Cloud, cloud, infrastructure, and data center migration initiatives. The role provides end-to-end coordination from application and interface readiness through MAT execution, Go/No-Go preparation, cutover, and operational handoff. The position serves as a primary liaison among application teams, migration engineering, cloud and solution architects, network and infrastructure teams, security organizations, operations teams, vendors, testing teams, and program leadership. Success requires a balanced combination of technical understanding, structured delivery management, governance discipline, and the ability to influence teams without direct authority. Based on program need and individual capability, the selected candidate may lead a blended portfolio or be aligned more heavily to MAT/Cutover or Interface Management while operating under the same common readiness framework. Job responsibilities

• Assigned applications meet defined MAT entry, execution, and exit requirements.
• Application interfaces, connectivity requirements, and technical dependencies are accurately documented and migration ready.
• Cutover plans, approvals, evidence, operational checkpoints, and Go/No-Go inputs are complete and decision ready.
• Risks, defects, blockers, actions, and schedule concerns are visible, owned, escalated, and driven to closure.
• Jira and supporting program artifacts provide an accurate and auditable view of migration readiness.
• Own and coordinate readiness activities for assigned applications across assessment, design, testing, migration, cutover, and operational transition.
• Facilitate readiness reviews, working sessions, status meetings, technical discussions, and stakeholder communications.
• Maintain clear entry/exit criteria, evidence requirements, approval checkpoints, dependencies, due dates, and accountable owners.
• Track and report readiness status, risks, issues, actions, decisions, defects, dependencies, and milestones in Jira and other approved program tools.
• Proactively identify gaps or schedule concerns and escalate material blockers with clear impact, ownership, and recovery actions.
• Coordinate MAT planning, entry, execution, defect management, retesting, and exit for assigned applications.
• Confirm test scope, environments, test data, resources, access, dependencies, expected evidence, and acceptance criteria are defined before MAT begins.
• Monitor test progress and ensure defects, constraints, and unresolved risks are assigned, prioritized, and tracked to disposition.
• Coordinate with application, testing, infrastructure, security, operations, and migration teams to resolve MAT blockers.
• Prepare concise readiness reporting and support formal MAT exit recommendations based on completed evidence and approved criteria.
• Review, validate, and maintain application interface inventories, dependency records, data flows, and supporting documentation.
• Analyze connectivity requirements including protocols, ports, endpoints, certificates, encryption, secure transport, authentication, routing, firewall, DNS, and network dependencies.
• Assess integration patterns and interface impacts resulting from cloud, infrastructure, network, platform, or hosting changes.
• Validate interface data quality, identify documentation gaps and technical risks, and coordinate corrective actions with accountable teams.
• Ensure interface tracking artifacts remain accurate throughout the migration lifecycle, including source/target changes and cutover sequencing.
• Coordinate resolution of interface-related issues and migration blockers across application owners, vendors, architects, network, security, infrastructure, and engineering teams.
• Support development and validation of cutover plans, runbooks, activity sequencing, resource coverage, communication plans, checkpoints, fallback considerations, and recovery actions.
• Confirm prerequisite approvals, change records, access, implementation tasks, interface activities, validation steps, monitoring, support coverage, and operational documentation are complete.
• Coordinate Go/No-Go preparation and provide an evidence-based view of readiness, open risks, exceptions, dependencies, and required decisions.
• Partner with operations and support teams to validate monitoring, incident routing, ownership, handoff, and early-life support arrangements.
• Support migration execution and post-cutover validation, ensuring issues are triaged, assigned, communicated, and tracked through stabilization.
• Review application architectures, integration patterns, interface designs, and migration solution assumptions with the appropriate technical teams.
• Coordinate with cloud engineering, solution architecture, infrastructure, network, security, and operations teams to resolve technical challenges and dependencies.
• Review encryption and secure transport requirements and identify security risks associated with integrations and connectivity patterns.
• Ensure migration solutions, interfaces, evidence, and execution activities align with applicable enterprise architecture, security, change, and governance standards.
• Route decisions and exceptions to the appropriate approving authority; maintain traceability of outcomes without substituting for formal approval functions. Required experience
• 5+ years of experience in project/program management, release management, technical delivery, application migration, infrastructure delivery, integration coordination, or a related discipline.
• Experience supporting application, cloud, infrastructure, platform, or data center migration programs.
• Demonstrated ability to manage risks, issues, actions, defects, dependencies, schedules, evidence, and cross-team commitments.
• Working knowledge of testing lifecycles, deployment, change management, cutover planning, operational readiness, and production support transition.
• Working knowledge of application integrations, interface inventories, connectivity concepts, protocols, ports, endpoints, encryption, certificates, and technical dependencies.
• Strong written and verbal communication, facilitation, stakeholder management, organization, and documentation skills.
• Ability to manage multiple applications and priorities in a complex, matrixed enterprise environment.
• Proficiency with Jira or a comparable work management platform, Microsoft Excel, SharePoint Online, PowerPoint, Teams, and Microsoft Office.
• Hands-on experience supporting AWS, AWS Outposts, private cloud, hybrid cloud, infrastructure modernization, or large-scale migration programs.
• Experience coordinating MAT, user acceptance testing, cutover, release, deployment, hypercare, or operational transition activities.
• Experience analyzing interfaces, integration patterns, network connectivity, security controls, or application dependency maps.
• Advanced Microsoft Excel skills and experience with Power BI and Power Automate for portfolio reporting, workflow, or readiness automation.
• PMP, PMI-ACP, Agile, Scrum, SAFe, ITIL, AWS Cloud Practitioner, or comparable certification.
