Are You a Fit?

We are seeking a highly skilled Atlassian Migration Engineer to lead a digital transformation: moving our infrastructure from Jira Server/Data Center to Jira Cloud. This is not just an administrative role; we need a "Data Architect" who can dismantle complex legacy systems and rebuild them into a streamlined, high-performing Cloud environment.

The ideal candidate is someone who bridges the gap between technical execution (API, Scripting) and strategic planning (Change Management, Stakeholder Communication).

Are You a Fit?

•
Proven Migration Experience: Hands-on experience with large-scale Jira Cloud migrations and instance consolidations.

•
Atlassian Ecosystem Expert: Deep knowledge of Jira architecture, Confluence, Bitbucket, and Jira Service Management (JSM).

•
Agile Proficiency: Solid experience working within Agile frameworks in enterprise-level environments.

•
Communication: Exceptional ability to explain technical migration roadmaps to non-technical cross-functional stakeholders.

Sounds awesome, right? Now, let’s make sure you’re a good fit for the role.

Must-have Skills

•
Lead Complex Migrations: Own the end-to-end migration lifecycle from Jira Server/Data Center to Cloud.

•
Instance Consolidation: Evaluate, merge, and clean up multiple Jira instances into a single, unified Cloud environment.

•
Workflow & Architecture: Design and map custom workflows, permission schemes, and issue types to ensure business continuity post-migration.

•
Data Integrity: Use Jira REST API, SQL, or JSON to extract, transform, and validate data, ensuring 100% accuracy during the transition.

•
Automation: Replace legacy automations with "Automation for Jira" and utilize ScriptRunner (Groovy) or Python to streamline repetitive migration tasks.

•
Strategic Planning: Build comprehensive Migration Runbooks, execute testing in Sandbox environments, and define robust Rollback procedures.

Nice-to-have Skills

•
Scripting: Proficiency in Groovy (ScriptRunner), Python, or Bash for custom data manipulation.

•
API Mastery: Advanced experience using Jira REST API for data validation and extraction.

•
Change Management: Familiarity with enterprise change control processes and staging/sandbox workflows.

•
Data Mapping: Advanced skills in Excel, JSON, or SQL for complex data reconciliation.

What we offer

• A High-Impact Environment

• Commitment to Professional Development

• Flexible and Collaborative Culture

• Global Opportunities

• Vibrant Community

• Total Rewards
