Senior Software Engineer – 3D Visualization (Unity)

Astura Medical • Irving, TX

4h • Onsite

About The Position

We are seeking a talented Senior Software Engineer – 3D Visualization (Unity) to build a custom, interactive 3D desktop and mobile application. In this role, you will develop a high-precision user interface that allows users to seamlessly align and fit custom 3D medical implants onto patient anatomy data. The input data will be generated from advanced 3D engineering software (such as Synopsys Simpleware), and your core mission will be to turn this high-fidelity data into an intuitive, interactive tool that runs smoothly on both standard PCs and touchscreen tablets.

Requirements

• Bachelor’s degree in engineering or equivalent experience.
• Minimum 5 years of professional experience developing interactive, non-gaming 3D applications using Unity.
• Advanced command of C# and object-oriented programming principles.
• Experience working with Unity’s New Input System (handling hybrid touch and mouse inputs) and UI frameworks (e.g., UI Toolkit or uGUI).
• Proven experience importing, scaling, and managing diverse 3D file formats (e.g., .STL, .OBJ, .3MF) at runtime or build-time.
• Strong understanding of linear algebra, vectors, quaternions, and coordinate system transformations (e.g., translating medical millimeter-scale data to Unity coordinates).
• Experience collaborating via Git, Perforce, or Plastic SCM.
• Candidates must be legally authorized to work in the United States without sponsorship now or in the future. Astura Medical is not currently sponsoring visas, including, but not limited to, H-1B, TN, or EAD, and we are not accepting visa transfers.

Nice To Haves

• Experience preparing and importing complex CAD data (e.g., STEP, IGES) into Unity using tools like Unity Pixyz or enterprise data pipelines.
• Exposure to medical imaging, medical device software, or engineering simulation applications (experience with software like Synopsys Simpleware, Materialise Mimics, 3D Slicer, or SolidWorks is highly valued).
• Familiarity with building automation scripts (C# or Python) to link Unity with external software workflows.

Responsibilities

• Develop and maintain a unified, responsive 3D user interface that functions flawlessly via mouse/keyboard (PC) and multi-touch gestures (Tablet).
• Code custom 3D interaction systems, including transformation gizmos (translate, rotate, scale), collision detection, and smart-snapping mechanics to precisely position implants against bone anatomy.
• Build robust data-ingestion pipelines to load, scale, and render 3D meshes and CAD geometries exported from external engineering software.
• Profile and optimize runtime performance (frame rate, memory usage) to ensure complex 3D structures load quickly and run smoothly on lower-powered tablet hardware.
• Maintain a modular, well-documented C# codebase optimized for long-term scalability and software updates.
