Project Manager - Atlassian Migration Expert

Role purpose: Lead complex migration programmes with a strong focus on Atlassian migrations (Jira/Confluence and related ecosystem), while also bringing broader enterprise migration experience (e.g., cloud, data/platform, application, tooling). You'll plan and deliver end-to-end migrations, ensuring robust ETL understanding where data movement/transformation is required and ensuring full end-to-end traceability from requirements through delivery, cutover, and post-migration assurance. Key responsibilities: Programme / project delivery Own the migration delivery plan end-to-end: discovery, design, build, test, cutover, hypercare, and transition to BAU. Drive scope, schedule, RAID, financials, governance, and stakeholder management across multiple teams and vendors. Build and maintain integrated plans (workstreams, dependencies, critical path), ensuring delivery at pace without compromising control. Establish and run delivery ceremonies: steering committees, workstream reviews, cutover rehearsals, go/no-go forums, and lessons learned. Atlassian migration leadership Lead Atlassian migrations across deployment models (e.g., Server/Data Center to Cloud, Cloud-to-Cloud consolidation, instance rationalisation). Manage migration requirements for: Projects/spaces, workflows, permissions, custom fields, apps/add-ons, schemas, and automation. Identity/access integration (SSO, SCIM where relevant), user provisioning, and governance. Ensure Atlassian-specific data quality, mapping, and configuration parity (or improved target-state design). Bring experience from other migration contexts (e.g., application modernisation, cloud adoption, platform/tooling consolidation, data migrations) and apply proven patterns and controls. ETL and data migration controls Partner with data/engineering teams to plan and govern ETL activities (extract, transform, load), including: Data profiling, mapping, cleansing rules, transformation logic, and reconciliation. Migration tooling, runbooks, job scheduling, and rollback/restore strategies. Define and track migration success metrics: completeness, accuracy, timeliness, and performance. End-to-end traceability and assurance Implement and maintain end-to-end traceability across the delivery lifecycle: Business requirements → epics/stories → build/config → test cases → defect resolution → release/cutover evidence. Establish audit-ready artefacts: decision logs, change approvals, test evidence, reconciliations, cutover outcomes, and post-migration sign-off. Ensure strong change control and configuration management, especially where multiple systems and data sets are migrating in parallel. Risk, compliance, and operational readiness Identify and manage migration risks (data loss, downtime, security/access, integration breaks, performance degradation). Coordinate non-functional requirements: security, resilience, performance, DR, logging/monitoring, and support readiness. Plan operational handover: support model, knowledge transfer, training, runbooks, and hypercare exit criteria. Required experience & skills Proven experience delivering complex migrations as a Project Manager, including Atlassian migration delivery (Jira/Confluence strongly preferred). Demonstrable experience leading non-Atlassian migrations (e.g., cloud/platform migrations, data migrations, tooling consolidation, application migration). Working understanding of ETL concepts , data mapping, reconciliation, and migration quality controls (not necessarily hands-on engineering, but able to govern effectively). Strong grasp of end-to-end traceability and delivery evidence from requirements to deployment and post-cutover assurance. Excellent stakeholder management across engineering, product owners, security, operations, and third-party vendors. Strong planning skills: dependency management, cutover planning, runbooks, and go/no-go governance. Comfortable working in Agile, waterfall, or hybrid delivery models.
