Job description

We’re seeking a hand‑on Senior VBA Developer with deep T‑SQL expertise and the ability to read and write MS Access 2003/VBA. You’ll reverse‑engineer and stabilize the legacy SnapShot application, design and build modern SQL‑centric data flows, and implement integrations that connect the current Access front end (on‑prem) + SQL Server back end ERP with the Infor system. The near‑term focus is delivering the first integration, followed by a broader modernization program (S4 migration to follow).

What You’ll Do

• Reverse‑engineer, read, and author MS Access 2003/VBA code; untangle ~100k lines of legacy logic to document workflows and stabilize critical functions.
• Design and implement SQL Server schemas (approx. 500 fields, with ~100 Q&A fields flowing into SnapShot) to support modernized processing.
• Build robust ETL/data ingestion pipelines (e.g., parsing output files and loading into SQL DB for downstream processing); automate validation and reconciliation.
• Integrate with Infor: design interfaces/APIs/bridge tables and orchestrations to pass configuration/estimator data between Access/SQL and the Infor ecosystem.
• Maintain on‑prem performance and reliability: indexing, query tuning, statistics management, isolation levels, and transactional integrity.
• Establish coding standards, version control, and technical documentation for legacy and modern components; implement unit/integration test harnesses.
• Partner with business (estimators, dealers) to map legacy rules to modern data structures; convert tribal knowledge into testable specifications.
• Prepare for the S4 migration (start‑to‑finish planning) by isolating dependencies, defining cutover strategies, and drafting rollback/safety nets.
• Drive secure handling of ERP data (authentication, role‑based access, auditing), and plan for multi‑year on‑prem operation before any cloud move.
