Senior Full-Stack Developer

Senior Full-Stack Developer

About the Role

We are looking for a senior full-stack developer to help modernize and expand our customer's internal business systems. The 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.
• Willingness to work onsite during night shift hours (between 9:00 PM – 11:00 PM Ph start time).

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.

Preferred Experience

• 7+ years of professional software development experience, ideally with senior-level ownership of production systems.
• 5+ years of C#/.NET and MS SQL Server experience.
• 3+ years building APIs, internal business applications, or integration-heavy systems.
• 2+ years with TypeScript/React or comparable modern frontend development.
• Entity Framework or Entity Framework Core.
• Microsoft Dynamics GP, SmartConnect, ERP systems, or accounting/operational databases.
• Azure services, hybrid on-premise/cloud systems, or cloud migration planning.
• Azure DevOps for source control, work tracking, build pipelines, release pipelines, or deployment automation.
• AI-assisted development tools used responsibly for coding, testing, documentation, troubleshooting, or analysis.
• Python utilities, scheduled automation, logging, monitoring, or CI/CD improvements.
• Legacy modernization involving FoxPro, Access, desktop applications, spreadsheets, or manual workflows.
• Operational systems for accounting, shipping, warehouse, manufacturing, distribution, or back-office teams.

Technical Environment

• Microsoft Dynamics GP 2018 and SmartConnect
• MS SQL Server
• C#, ASP.NET, and Entity Framework
• TypeScript and React
• Python utilities
• Legacy FoxPro applications
• Windows Server and Task Scheduler
• Azure and Azure DevOps
• AI-assisted development tools
• On-premise application and database infrastructure

What Success Looks Like

A successful developer can be assigned a project, understand the scope, investigate the relevant data and systems, create an implementation plan, present it for approval, and execute it while regularly updating stakeholders and the lead engineer.

Over time, this person should become familiar with more company systems while remaining effective on new and unrelated projects. They should improve the reliability of our applications and integrations, strengthen documentation, collaborate well with the development team, and help move more company functionality into maintainable web-based tools.

Ideal Candidate Profile

The ideal candidate is a practical senior developer who is comfortable with both modern application development and older business systems. They can talk to users, understand the business problem, work through database details, build the application or integration, document the result, and support it after release.

This role is a strong fit for someone who likes solving real operational problems and can bring structure to an environment that includes both legacy systems and newer web applications.

Example Projects

• Build a bill of lading generation application with a React frontend, C# API, and MS SQL database integration.
• Convert manual tools or backend-only workflows into secure internal web applications.
• Modernize scheduled C# applications with better logging, error handling, and support documentation.
• Create administrative CRUD tools for company-specific data and operational processes.
• Build external data integrations with audit history, timestamps, validation, and reconciliation.
• Document data flows between Dynamics GP, SmartConnect, SQL Server, scheduled jobs, and internal applications.
