About the Role


We are looking for a senior full-stack developer to help modernize and expand our internal business systems. Our environment is data-heavy and Microsoft-centered, with Microsoft Dynamics GP 2018, SmartConnect, MS SQL Server, scheduled C# applications, small Python utilities, legacy FoxPro applications, and a newer TypeScript/React web application with a C# backend API.

This role requires someone who can work independently across applications, databases, integrations, and business processes. The right person can investigate unfamiliar systems, create clear implementation plans, write useful documentation, communicate progress, and deliver reliable production systems with minimal supervision.

What You Will Do


  • Own internal application projects from discovery and planning through build, deployment, documentation, and support.
  • Build web applications and APIs using TypeScript, React, C#, ASP.NET, and MS SQL Server.
  • Design, update, and troubleshoot SQL Server tables, views, joins, stored procedures, and queries across multiple databases.
  • Build safe data integrations, imports, exports, and ETL-style workflows with history, timestamps, validation, reconciliation, and failure handling.
  • Modernize manual processes, scheduled jobs, legacy utilities, and backend workflows into maintainable applications.
  • Document system behavior, data flows, implementation plans, support procedures, and project status.
  • Collaborate with other developers and the lead engineer on technical plans, code reviews, implementation details, and shared development practices.


Required Experience


  • Senior-level software development experience with practical ownership of production systems.
  • Strong MS SQL Server skills, including complex joins, views, stored procedures, query tuning, data troubleshooting, and multi-database work.
  • Strong C# experience, including modern C# and API development with ASP.NET or ASP.NET Core.
  • Experience building business-focused web applications with TypeScript and React.
  • Experience with ETL workflows, external data integrations, imports, exports, or automated data processing.
  • Ability to work with existing databases, legacy applications, and imperfect documentation.
  • Experience deploying, supporting, or troubleshooting applications on Windows servers.
  • Strong writing skills for implementation plans, data flow notes, project updates, and support documentation.
