Full Stack Developer - Kennesaw, GA

Role Summary

United Contractor Services is seeking a Full Stack Developer to build, enhance, and support the internal applications and tools our field and office teams rely on every day. This role covers the full lifecycle - front‑end interfaces, back‑end services, databases, and the APIs that tie them to our core business platforms.

The ideal candidate is both hands‑on and analytical: someone who can write clean, maintainable code, design a sensible data model, debug a production issue, and also sit down with accounting, operations, or a project team to understand what they actually need before writing a line of it.

This is not a ticket‑based support role. This position owns the applications it builds, end to end.

Technology Environment (examples)

• Internal web applications and dashboards supporting field and office operations
• Viewpoint Vista (ERP) and Procore (project management) data and APIs
• Payroll and HR systems including ADP / Paylocity
• Microsoft ecosystem - M365, Entra ID, Teams, Power Platform, Azure
• ManageEngine ServiceDesk / Freshservice

Key Responsibilities

Application Development

• Build and maintain internal web applications from front end through back end, including UI, business logic, APIs, and database layers.
• Design and optimize relational database schemas, queries, and stored procedures.
• Develop and consume REST APIs and webhooks to move data between internal applications and core business platforms.
• Write readable, testable, maintainable code and participate in code review.

Business Analysis & Solution Design

• Partner with accounting, operations, HR, project teams, and IT to understand workflows and translate them into working software.
• Identify manual processes that can be replaced with purpose‑built tools or automation.
• Turn business requirements into technical designs, data models, and delivery plans.

Quality, Deployment & Support

• Test, deploy, monitor, and support applications in production.
• Troubleshoot and resolve defects, performance problems, and data integrity issues across the stack.
• Implement logging, alerting, validation, and error handling so problems surface before users report them.

Documentation & Standards

• Document application architecture, data models, field definitions, and business rules.
• Establish standards for source control, API usage, authentication, and change management.
• Ensure applications meet security, access control, and audit requirements.

Continuous Improvement

• Evaluate frameworks, third‑party tools, and APIs that could accelerate delivery.
• Improve the scalability, maintainability, and performance of existing applications.
• Proactively recommend improvements to leadership rather than waiting to be asked.

Required Qualifications

• 3+ years of professional software development experience across front end and back end
• Proficiency in at least one back‑end language (C#, Python, JavaScript/Node, etc.)
• Front‑end experience with HTML, CSS, JavaScript, and a modern framework (React, Angular, Vue, or similar)
• Strong SQL and relational database design skills
• Hands‑on experience building and consuming REST/JSON APIs, including authentication (OAuth, tokens)
• Experience with source control and standard development workflows (Git)
• Proven ability to translate business requirements into working software
• Strong troubleshooting and root‑cause analysis skills
• Comfortable working independently and owning outcomes

Preferred Experience

• Viewpoint Vista, Procore, ADP, or Paylocity integration or reporting experience
• Microsoft ecosystem development (Azure, Azure Functions, Power Platform, Entra ID)
• Cloud hosting, CI/CD pipelines, and containerization
• Reporting and BI tools (Power BI, SSRS)
• Construction or project‑based business environments
