Senior .NET Engineer / Team Lead

Summary:

We are seeking a Senior .NET Engineer / Team Lead to drive both the technical execution and day-to-day leadership of an engineering team responsible for a safety-critical platform used by schools, public safety organizations, and law enforcement agencies.

This is a hands-on leadership role, combining active software development with team leadership responsibilities. You will guide a multi-phase platform modernization—transitioning a legacy VB.NET Web Forms application to modern ASP.NET Core—while ensuring reliable, secure, and high-quality delivery through strong agile execution and engineering practices.

You’ll operate in a greenfield-meets-brownfield environment, building modern systems while incrementally improving and decommissioning legacy components. This role also includes ongoing ownership and evolution of the platform and team beyond the migration effort.

We Value: 

• Honest, open, frequent, and clear communication 
• Honoring commitments and meeting goals and deadlines 
• Curiosity, passion, and intellect 
• Supporting, teaching, learning, and succeeding together 
• Preparation, engagement, responsiveness, and highly efficient use of time and resources 
• Being the best at what we do 

You Have:

• A passion for technology and cutting-edge tools, approaches, and architectures 
• An aptitude for analytical problem solving 
• The ability to quickly learn new technologies 
• An attitude where no technical challenge is too great 
• The ability to communicate and collaborate cross-functionally, and work well in a team environment 
• Receptivity to feedback, challenge, and growth

Key Responsibilities:

• Technical Leadership & Architecture

• Define and drive the technical roadmap for a phased migration from VB.NET Web Forms to ASP.NET Core (strangler fig pattern)
• Ensure team implementations align with approved architecture and engineering standards
• Make team-level design decisions and facilitate architecture discussions
• Identify and reduce technical debt to maintain a scalable, maintainable codebase
• Architect and implement core system components, including data access and service layers
