How to Apply for Software Engineer, Geometric Algorithms

at Velo3D

🏢 About Velo3D

Velo3D is revolutionizing metal 3D printing specifically for clean energy and transportation applications, moving beyond prototyping to full-scale production. Unlike generic 3D printing companies, they focus on solving complex manufacturing challenges for industries like aerospace and energy with their intelligent Fusion technology. Working here means contributing directly to sustainable innovation in critical sectors.

About This Role

This role involves developing geometric algorithms that analyze complex 3D designs, generate supports, and create precise lasing instructions for metal 3D printing systems. You'll work hands-on with large geometric datasets (meshes, polygons) to solve real-world manufacturing problems that directly impact product quality and production efficiency. Your work bridges digital geometry with physical manufacturing outcomes.

💡 A Day in the Life

A typical day involves developing and optimizing C++ algorithms for processing complex 3D geometry data, collaborating with manufacturing engineers to understand production challenges, and testing geometric solutions on real-world part designs. You might profile performance of mesh processing routines, implement parallel computations for faster analysis, and validate algorithms against physical printing results.
