What You’ll Do

• Develop and optimize advanced reconstruction algorithms for X-ray CT and related imaging modalities

• Design physics-based and data-driven reconstruction pipelines

• Implement machine learning and deep learning approaches for reconstruction, artifact reduction, and image enhancement

• Solve inverse problems using advanced numerical optimization techniques

• Build high-performance implementations using GPU acceleration (CUDA) and parallel computing methods

• Process and analyze large-scale 3D volumetric datasets

• Prototype new algorithmic concepts and transition them into production software

• Design and execute simulation and experimental validation studies

• Collaborate closely with hardware, applications, and software engineering teams

• Document algorithms, validation results, and software modules clearly and thoroughly

• Contribute to technical publications, patents, white papers, or internal innovation initiatives

• Present technical findings internally and externally, including at conferences when appropriate

What You Bring:

• Master’s degree and/or relevant work experience in technical field:

  • Computer Science

  • Electrical Engineering

  • Applied Mathematics

  • Imaging Science

  • Computational Physics

• Experience with modern ML frameworks (e.g., PyTorch, TensorFlow)

• Experience processing and analyzing 3D or volumetric datasets

• Strong understanding of:

  • Inverse problems

  • Numerical optimization

  • Signal and/or image processing

• Experience with GPU programming and CUDA

• Proficiency in Python and/or C++

• Strong analytical thinking and experimental validation skills

Helpful (But Not Required):

We recognize that strong candidates may not meet every listed qualification. Additional experience that may be beneficial includes:

• Experience with tomographic reconstruction methods (e.g., FBP, iterative reconstruction)

• Background in computational physics or imaging system modeling

• Experience transitioning research code into production environments

• Publication or patent experience

• Familiarity with high-performance computing environments

Why Join NSI:

• Work on cutting-edge CT technology used across high-impact industries

• See your algorithms move from research to real-world industrial systems

• Collaborate with multidisciplinary experts across hardware, software, and applications

• Contribute to innovation in nondestructive testing and advanced imaging
