Salary Range: $95,000.00 To $115,000.00 Annually

Position Overview

The Full-Stack Business Applications Developer works across C#/.NET, Python, and SQL to build and maintain the applications that run the business - adding features, fixing issues, and creating reports - while handling the operational and data investigations that keep our systems running smoothly. In a Microsoft SQL Server and MySQL environment, this role resolves technical and business-data issues, supports EDI and data-import pipelines, and continuously improves the internal applications our teams rely on. It combines hands-on application development with operational support and requires strong problem-solving skills across the full stack.

• Application Feature Development: Design, build, and ship new features across the Blazor/MAUI client application and the C#/.NET API, following the established application architecture.
• Maintaining Existing Codebases: Debug, refactor, and enhance the existing C#, Python, and SQL codebases to improve functionality, correctness, and performance.
• Operational Investigations & Data Fixes: Investigate business-data issues - including pricing discrepancies, EDI and UPC problems, planogram classification, and promotion or import matching - using established procedures and appropriate change controls. Resolve data and code-level root causes, and clearly document or elevate complex issues when appropriate.
• SQL & Reporting: Write, optimize, and debug SQL and stored procedures across Microsoft SQL Server and MySQL, and build reports end-to-end (stored procedure, report definition, deployment, and permissions).
• EDI & Data Imports: Maintain the trading-partner EDI and vendor/customer import pipelines, and triage, reprocess, and reconcile failed or exception imports.
• Reliability & Error Triage: Monitor client-error telemetry and back-end processes, prioritize and resolve production issues, and handle routine master-data and user-account maintenance.
• Testing & Quality: Write automated tests at the appropriate layer (unit, integration, and end-to-end) and keep the test suites passing before changes ship.
• Collaboration & Issue Resolution: Communicate directly with employees across departments to understand reported issues, gather context, reproduce problems, and carry them through resolution. Partner with the IT/IS Director and business teams to streamline processes and increase efficiency, escalating complex issues as needed.

• Adaptability and Flexibility: Thrives in dynamic environments with shifting priorities, works comfortably within an established and well-documented architecture, and remains calm under pressure while delivering results.
