Job Summary

Roles

 

Develop high-performance 3D visualization solutions for engineering/scientific data, focusing on rendering efficiency, large dataset handling, and advanced analytical visualization capabilities.

 

Responsibilities

 

Core 3D Visualization & Rendering (Primary)

 

  • Design and implement high-performance 3D visualization systems for large-scale engineering datasets (sensor data).
  • Develop and optimize rendering pipelines using OpenGL / WebGL / similar graphics APIs.
  • Translate raw MFL data into meaningful visual representations such as:
    • Surface/pipe visualization
    • Defect/anomaly highlighting (heatmaps, overlays)
    • Spatial transformations and camera control
    • Interactive navigation (zoom, pan, rotate, object selection)

 

Performance & Optimization (Critical)

 

  • Optimize rendering performance for large datasets (MB–GB scale).
  • Implement GPU-based techniques using shaders (GLSL or equivalent).
  • Apply rendering optimizations such as:
    • Level of Detail (LOD)
    • Batching and efficient buffer management
  • Ensure smooth interaction and responsiveness under heavy data loads

 

Data-Driven Visualization

 

  • Integrate structured and unstructured engineering data into visualization pipelines
  • Design efficient data-to-geometry mapping strategies.
  • Support real-time or near-real-time data updates.
  • Enable analytical visualization workflows (e.g., anomaly exploration, comparison views).

 

Cross-Platform Adaptability

 

  • Desktop environments (C++ based).
  • Web environments (JavaScript / WebGL based).
    • Make architectural decisions that allow portability and extensibility.

 

Engineering & Design Collaboration

         

  • Work closely with domain experts to translate MFL inspection requirements into visual outputs.
  • Collaborate with architects and product teams to design scalable visualization solutions (JavaScript / WebGL based).
  • Contribute to technical design decisions related to rendering architecture and data handling.
