In this role, you will lead the technical analysis, extraction, and migration of a legacy Hyland OnBase environment into a modern ECM ecosystem featuring OpenText, Camunda, and Microsoft SharePoint.

• Collaborate with enterprise architects and business stakeholders to map OnBase metadata, security models, and document structures to OpenText, SharePoint, and Camunda formats.
• Design and execute end-to-end ETL routines to migrate high-volume document stores and historical data with zero data loss.
• Develop custom scripts, C# API routines, or OnBase Unity API extensions to extract documents, annotations, audit logs, and metadata from OnBase disk groups and databases.
• Identify and resolve complex data discrepancies, orphaned records, or corrupted files before and during migration.
• Configure data transformation pipelines for ingestion into OpenText repositories and SharePoint document libraries.
• Deconstruct complex OnBase Workflows and WorkView applications and translate business logic into Camunda BPMN models and process flows.
• Support parallel testing, dual-run strategies, and post-migration validation to ensure system integrity and compliance.
• Document legacy system configurations, migration mappings, technical workflows, and final decommissioning procedures.

Required Qualifications:

• 5+ years of hands-on experience developing, configuring, and maintaining Hyland OnBase platforms (Unity API, C# scripting, OnBase database schema, WorkView, Workflow, Keyword Types).
• Proven experience executing at least one large-scale migration project moving off OnBase to a modern ECM platform.
• Advanced proficiency in SQL Server / Oracle, complex T-SQL, data extraction scripts, and ETL procedures.
• Strong C# / .NET development skills, particularly using Unity API or REST APIs for OnBase content extraction.
• Solid understanding of document management practices in Microsoft SharePoint, OpenText Content Suite/xECM, and/or Camunda process automation.
• Experience with high-volume document migration, data validation, hash verification, and audit tracking.
• Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:

• Active or past Hyland certifications (OCA, OCWA, OCAPI).
• Experience with REST/SOAP APIs, Middleware/MuleSoft, or Azure Data Factory.
• Experience working in Agile (Scrum or Kanban) environments.
