About The Position

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.

Requirements

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

Nice To Haves

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

Responsibilities

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.
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.
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.
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.
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.
