Instrumentation Software Engineer Jobs (NOW HIRING)

Job Title: Software Engineer

Job Description

The Software Engineer will join the applications team and support a mature Windows desktop application that reconstructs complex data into 3D graphics for customers. This role focuses on maintaining and enhancing an existing application that was developed five years ago, including fixing defects, improving performance, and implementing new features to support advanced 3D visualization and analysis workflows.

Responsibilities

• Support and maintain an existing Windows desktop application that reconstructs scientific and engineering data into 3D visualizations.
• Diagnose, troubleshoot, and fix bugs in a complex, multithreaded C# application to ensure stability and reliability.
• Design, develop, and implement new features and enhancements using C#, WPF, .NET, and related tools and frameworks.
• Apply MVVM design patterns to structure and organize application components for maintainability and scalability.
• Work with 3D visualization components to present reconstructed data clearly and accurately for end users.
• Use Microsoft Visual Studio and SQL Server to develop, debug, and optimize application functionality and data access.
• Debug multithreaded code to resolve performance issues, race conditions, and concurrency-related defects.
• Collaborate with other team members in the applications team to understand requirements and translate them into technical solutions.
• Contribute to continuous improvement of the application’s architecture, performance, and user experience based on customer and internal feedback.

Essential Skills

• Bachelor's degree in computer systems, material science, or physics.
• 5+ years of experience with Windows desktop application development.
• 5+ years of experience with C#.
• 5+ years of experience with development tools and frameworks such as Microsoft Visual Studio and .NET.
• 5+ years of experience working with SQL Server.
• 5+ years of experience applying MVVM design patterns in application development.
• 5+ years of experience with 3D visualization in software applications.
• 5+ years of experience debugging multithreaded applications.
• Experience developing Windows desktop applications using WPF.

Work Environment

The software supports advanced instrumentation used in national laboratories and semiconductor-related companies to research, analyze, and improve materials such as metal alloys and to perform quality control. In typical workflows, a sample is placed into the instrumentation, a high-voltage laser pulses the material, and atoms are released. A detector captures the location and type of atoms, and this data is collected, stored, and then processed by the application the team develops to reconstruct detailed 3D visualizations for customers. The environment is highly technical and data-driven, with close interaction between scientific instrumentation outputs and specialized desktop software that runs on Windows using tools such as Microsoft Visual Studio, .NET, WPF, SQL Server, and 3D visualization technologies.
