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.
