Water Resources Group (WRG) — a family of self-performing civil construction companies that has built water and wastewater treatment infrastructure for more than 40 years — is hiring an Application Developer for its Deerwood or Monticello, Minnesota office. The role builds, maintains, and improves the internal business applications employees rely on every day. It is hands-on for someone who enjoys both writing code and talking with the people who use it, with a listed base salary range of $85,000 – $125,000 and a comprehensive benefits package.
About Water Resources Group — Civil Construction Company
Companies: Includes Rice Lake Construction Group and Rice Lake West
Work: Water and wastewater treatment infrastructure, plus heavy civil and commercial/industrial projects
Region: Upper Midwest and Mountain West
Scale: Roughly 420 employees delivering more than 45 active projects a year
Culture: Award-winning safety program and a focus on building tools that others can support
Why This Developer Role Stands Out
Direct Users: Meet the employees who use your applications and turn their needs into practical solutions
Growing Responsibility: Take on more deployment and production support over time
Modern Tooling: Use AI-assisted development tools, with code reviewed and validated by you
Stable Industry: Water infrastructure construction is a long-running, essential sector
Position Overview
The Application Developer at WRG builds, maintains, and improves internal business applications. Working alongside the company’s technology leadership, you will keep existing applications running smoothly, enhance them as they move into broader use, and take on growing responsibility for deployment and production support. A big part of the job is listening: you will meet with employees and business leaders, understand what they need, and deliver practical, reliable solutions — including integrations with company systems such as Sage 300 CRE and Sage Paperless.
Why This Role Matters: A construction company runs on its internal tools — job costing, document management, reporting. When those applications are reliable and easy to use, project teams spend less time fighting software and more time building. As Application Developer you are the person who makes that happen, and who makes sure no system depends on the knowledge of a single person.

- Support integration with Sage 300 CRE and Sage Paperless
- Keep dependencies, base images, and supporting infrastructure patched and current
- Help consolidate and retire legacy deployments as applications are replaced
Standards & Documentation
- Follow and help improve standards for development, deployment, security, and support
- Apply sound security practices, including SSO, environment-based credentials, and least-privilege database access

Required
- 3–6 years of experience developing and supporting business applications in a production environment

- Experience with Microsoft SQL Server, ODBC connectivity, or SSO
- Experience with ERP/accounting systems, especially Sage 300 CRE or Sage Paperless
- Bachelor’s degree in computer science, information systems, or a related field — equivalent experience will be considered
Working Conditions
