Sr. Staff Software Engineer, Digital Modeling

About the Role

Key Responsibilities

• Develop tools to manipulate anatomical models derived from CT scans, including segmentation, smoothing, and alignment.
• Implement Boolean operations, implant insertion logic, and model fusion using CAD-level kernels (e.g., OpenCascade).
• Design systems for measuring regional anatomical properties such as vertebral height, curvature, and alignment.
• Create and apply mesh simplification, remeshing, and surface quality improvement strategies.
• Build tools that simulate how implant variations affect spinal anatomy and biomechanics.
• Develop parameter-driven models and transformation systems that respond to implant sizing, positioning, and morphology.
• Integrate implant data exported from Onshape or equivalent STEP-based sources.
• Support development of web-based 3D interfaces using Three.js, Babylon.js, or vtk.js for visualizing anatomy, implants, and surgical plans.
• Collaborate with product and UX teams to build intuitive interfaces for surgical modeling workflows.
• Interface with medical imaging pipelines (e.g., DICOM to STL/STEP) and maintain data integrity across 3D modeling workflows.
• Optimize modeling and Boolean performance for large-scale anatomical datasets in both browser and server-side environments.

Requirements

• Deep experience with 3D modeling, geometry processing, or CAD/CAM systems.
• Strong command of JavaScript/TypeScript and Node.js.
• Hands-on experience with OpenCascade (or other CAD kernels), including mesh/B-Rep handling, STEP/IGES import, and surface operations.
• Familiarity with WebAssembly, Emscripten, and JSWASM memory management.
• Solid foundation in math for 3D geometry, including transformations, normals, and spatial queries.
• Knowledge of rendering pipelines and WebGL-based visualization (e.g., Three.js, Babylon.js, vtk.js).
• Understanding of DICOM, STL, or segmentation workflows is a strong plus.
• Candidates with a Bachelor's or Master's degree in Computer Science, Biomedical Engineering, Computational Geometry, or a related field.
• Alternatively, candidates without a formal degree with 7+ years of relevant professional experience, including at least 4 years of deep, hands-on work in 3D modeling and CAD/CAM systems.

Nice to Have

• Experience with CAD, simulation, or surgical planning platforms.
• Knowledge of medical imaging workflows such as DICOM, STL, or segmentation processes.

Qualifications

• Bachelor's or Master's degree in Computer Science, Biomedical Engineering, Computational Geometry, or a related field.
• Or 7+ years of relevant professional experience with at least 4 years of deep, hands-on work in 3D modeling and CAD/CAM systems.

Benefits & Perks

• Competitive salary and benefits.
• 100% paid monthly healthcare, dental, and vision insurance premiums.
• 401(k) plan with employer matching.
• Unlimited PTO.
• Expected pay range: $170,000 - $200,000 annually plus bonus.
