Title: C# Software Engineer III (Modern .NET Core)

Locations: Lehi or Logan or Mendon (hybrid schedule, 3x/wk onsite)

Target Start Date : ASAP

Long-Term Contract (2-3 years)

Pay Rate : $60.00-$70.00 (DOE)

Our client, a global leader in advanced autonomous and robotic solutions across multiple industries, is seeking a C# Software Engineer III to join a highly technical, architecture-driven engineering team. This group builds and supports large-scale, multi-tier applications (600–800 projects within a single application ecosystem) across both desktop and web environments.

This role is ideal for an engineer with deep experience in C# and modern .NET Core (not limited to ASP.NET/web development) who understands how systems are designed—not just built—and thrives in an environment that values clean architecture and strong engineering fundamentals.

What You'll Do

• Design, develop, and maintain applications using C# and modern .NET Core / .NET (latest versions)
• Contribute to a complex, multi-tier architecture supporting desktop and web applications
• Apply object-oriented design principles to build scalable, maintainable systems
• Implement and leverage dependency injection and modern architectural patterns
• Work with SQL Server and Entity Framework for data access and persistence
• Collaborate on system design, architecture decisions, and performance improvements
• Troubleshoot issues across application layers and enhance system reliability

What We're Looking For

Required:

• 5+ years of experience with C# and modern .NET Core / .NET
• Deep understanding of object-oriented programming (OOP)
• Experience with dependency injection
• Solid experience with SQL Server and application/data interaction
• Experience with Entity Framework or similar ORM tools
• Understanding of multi-tier architecture and its real-world application
• Experience working on complex, enterprise-level applications
• Ability to clearly articulate technical and architectural concepts

Preferred:

• Experience with desktop application development (not just web-based / ASP.NET)
• Familiarity with MVC and modern architectural patterns
• Background in C++ or experience with real-time systems/devices
• Exposure to large, highly modular application environments

What Sets You Apart

• You understand the "why” behind architectural decisions
• You've worked on large, complex systems, not just smaller applications
• You bring depth of knowledge, not just surface-level framework experience
• You're comfortable discussing design, scalability, and system structure

Why Join

• Work on large-scale, technically challenging systems
• Be part of a team that prioritizes engineering rigor and strong architecture
• Collaborate with experienced engineers and grow your technical depth
• Join a team that is raising the bar and investing in long-term quality
