Job summary

Round-Peg Solutions (RPS) is seeking a sharp computational geometry engineer to design and implement core geometry algorithms for mesh and NURBS surfaces. You will tackle challenging spatial reasoning with BVH structures, octrees, and ray casting, while writing high-performance C++ at the heart of the product's geometry engine.

You will collaborate in a small, fast-moving team to define how complex 3D shapes are represented, combined, and simplified in production, bringing rigor and precision to

Qualifications

• Strong, proven C++ fundamentals are non-negotiable.
• Experience with computational geometry: mesh modeling, B-rep/NURBS, CAD/CAM or similar.
• Solid algorithmic thinking and problem-solving abilities.
• Background in math, physics, computer graphics, or 3D-heavy engineering.
• Rust experience is a strong plus.
• US Citizenship or Green Card required.
• Ability to thrive in a small, fast-moving team taking on problems without a playbook.

Responsibilities

• Designing and building geometric algorithms for mesh and B-rep/NURBS surface modeling.
• Solving spatial reasoning problems using BVH, octree/quadtree, and ray tracing/casting techniques.
• Writing performant, low-level C++ at the core of the product's geometry engine.
• Working closely with a small, high-caliber team to shape how complex 3D shapes are represented, combined, and simplified in production.
• Bringing rigor and precision to problems with no off-the-shelf solution.

Job description

Interested in a career solving 3D geometry problems that don't exist anywhere else — at the mathematical core of next-generation manufacturing technology? Are you a sharp computational geometry engineer with the algorithmic depth to build systems others rely on? Do you want to be one of the first five people to define how this technology takes shape? If so, this opportunity may be the right next step for you.

Responsibilities:

• Designing and building geometric algorithms for mesh and B-rep/NURBS surface modeling
• Solving spatial reasoning problems using BVH, octree/quadtree, and ray tracing/casting techniques
• Writing performant, low-level C++ at the core of the product's geometry engine
• Working closely with a small, high-caliber team to shape how complex 3D shapes are represented, combined, and simplified in production
• Bringing rigor and precision to problems with no off-the-shelf solution

Qualification:

• Strong, proven C++ fundamentals — this is non-negotiable
• Real experience with computational geometry: mesh modeling, B-rep/NURBS, CAD/CAM, or similar
• Solid algorithmic thinking — this matters more than any single tool or library on your resume
• A background in math, physics, computer graphics, or 3D-heavy engineering
• Rust experience a strong plus
• US Citizenship or Green Card required
• The ability to thrive in a small, fast-moving team taking on problems without a playbook

You’ll have the opportunity to play a pivotal role creating next generation products that help bridge the gap between digital design and physical manufacturing with real ownership over developing manufacturing automation systems.

This role has a strong compensation package with full benefits, equity options, 401k, and extensive PTO.
