About the Job

Requirements

  • A five-year higher-education qualification (BAC+5) is required.
  • At least five years of experience on comparable Data/BI assignments is required.
  • Strong proficiency in SSIS, SQL Server, and T-SQL in legacy or on-premise environments is required.
  • Recent, significant experience developing, maintaining, and diagnosing SSIS packages running in production is required.
  • Proficiency with Visual Studio/SSDT to open, analyze, modify, and deploy SSIS projects is required.
  • Daily use of Git and Azure DevOps for version control and collaborative code work is required.
  • Ability to quickly read and explain an existing SSIS package, identify its weaknesses, and propose a migration target is required.
  • Demonstrated experience designing and developing complex ETL flows is required.
  • A good understanding of decision-support architectures, including data warehouses, datamarts, data pipelines, and consuming systems, is required.
  • Experience taking over existing processes, reverse-documenting them, and working in partially mapped environments is required.
  • Practical Power BI knowledge sufficient to adapt connections and make targeted corrections is required; a complete report redesign is not required.
  • The candidate must be autonomous and operational quickly, and able to work in tandem with a Data designer without an extended ramp-up.
  • The candidate must be a confirmed consultant directly involved in delivery, rather than serving as a project director or full-time architect.
  • The candidate must use artificial intelligence judiciously to accelerate analysis, documentation, development, or testing while strictly respecting client security and confidentiality rules.

Responsibilities

  • Audit SSIS programs and packages currently running in production.
  • Understand the logic, sources, transformations, business rules, dependencies, and destinations of existing packages.
  • Help map existing processes and qualify data flows that are not yet well documented.
  • Design, develop, test, and document ETL processes needed to feed the data warehouse and datamarts in the new architecture.
  • Reproduce or adapt flat-file extracts and exchanges for external partners.
  • Take over and secure operational data flows, including those feeding CRM and the telephone platform.
  • Analyze the inputs and consumers of each flow, clarify its business purpose, and identify gaps against the target architecture.
  • Work with the Data design lead to translate architectural direction into operational development.
  • Contribute to designing solutions for topics that have not yet been fully scoped when needed.
  • Participate in testing, cross-functional acceptance testing with consuming applications, defect correction, and production deployment preparation.
  • Make minor changes to existing Power BI reports, particularly their connections to the new architecture and related compatibility issues.
  • Document development, data mappings, transformation rules, and operating procedures.
  • Quickly flag risks, dependencies, data inconsistencies, and areas with insufficient definition.

Desired Qualifications

  • Practical experience with GitHub Copilot or comparable tools is preferred.
