Full Stack Developer

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.
