We are looking for an experienced .Net Software Developer to join a non-profit organization in Middleton, Wisconsin on a Long-term Contract assignment. This position will support digital products used by educators and students, with a strong focus on application stability, production support, and ongoing software quality. The role blends hands-on development with support leadership, partnering closely with product, infrastructure, QA, and customer-facing teams to improve reliability and user experience.

Responsibilities:
Lead the day-to-day software support function by guiding technical work, reviewing code, coordinating releases, and ensuring issues are followed through to resolution.

Partner with technical leads and stakeholders to strengthen product readiness, clarify support ownership, and improve deployment outcomes.
Contribute actively within an Agile team by estimating work, identifying delivery risks, and participating in planning and execution discussions.
Monitor operational concerns such as alerts, storage issues, and queue-related warnings, and help address them before they affect end users.
Support vulnerability review and remediation efforts by working with development and infrastructure teams to prioritize and address security findings.
Adapt across multiple initiatives and technologies, shifting priorities effectively while maintaining clear communication on progress, blockers, and risks.

Requirements

7+ years of software development experience, including strong hands-on work with .NET, C#, ASP.NET, and ASP.NET MVC.
Demonstrated experience building and supporting web applications with Angular 8+ and solid knowledge of JavaScript, HTML5, and CSS3.
