Senior Data Migration Engineer

Senior Data Migration Engineer Our client is looking for a Senior Data Migration Engineer to support a large-scale cloud and data migration assessment programme. Working closely with the Lead Cloud & Data Architect, this role will focus on hands-on technical discovery, environment analysis, and operational assessment across complex infrastructure and application estates. The successful candidate will help ground the assessment in real-world system configurations, dependencies, and operational realities while contributing to migration planning and technical validation activities. Responsibilities • Execute technical discovery activities across infrastructure, databases, applications, and integrations using inventory tooling, configuration exports, and targeted system analysis. • Perform detailed assessments of database, application, operating system, and infrastructure configurations to identify constraints, customizations, dependencies, and operational challenges. • Document current-state “as-built” views of key systems including topology diagrams, data flows, scheduling processes, integrations, and workload dependencies. • Support migration planning by identifying operational and technical risks such as undocumented processes, manual interventions, access limitations, fragile integrations, and unsupported components. • Conduct targeted prototyping and dry-run migration exercises where appropriate, including lift-and-shift testing of representative non-critical workloads to validate migration assumptions. • Assist in defining migration runbooks, operational checklists, and technical execution processes that will be used during future migration waves. • Collaborate closely with architects, infrastructure teams, and client stakeholders to validate findings and ensure technical accuracy across the assessment. • Support the preparation of final assessment deliverables by providing technical evidence, detailed findings, configuration analysis, and implementation considerations. Requirements • 6–8+ years of experience in senior engineering roles focused on database, infrastructure, cloud, or migration engineering. • Strong hands-on expertise with SQL Server, Windows Server, Linux environments, and Microsoft Azure workloads. • Comfortable working directly with logs, scripts, configurations, infrastructure tooling, and system-level diagnostics. • Experience supporting cloud migration, infrastructure modernization, or large-scale transformation initiatives. • Strong understanding of infrastructure dependencies, operational processes, integrations, and enterprise application environments. • Ability to translate technical findings into structured, client-friendly documentation and assessment outputs. • Strong collaboration and communication skills with the ability to work effectively alongside architects, engineers, and client stakeholders. • Experience within regulated, enterprise, or public sector environments is highly desirable.
