C++ CAD Software Engineer

Rubypoint | C++ CAD Software Engineer | Remote (US) | $95K–$125K | US Citizens Only We're building a computational geometry engine from scratch in C++20. B-Rep modeling, surface-surface intersection, tolerance-aware geometric algorithms, and next-gen data exchange formats like QIF and STEP AP242. Clean codebase, no legacy code, no C++98. If you've worked on a geometry kernel, CAD internals, or computational geometry libraries, you know how rare it is to find a modern codebase in this space. We're looking for someone who has actually implemented or worked closely with things like half-edge data structures, NURBS/spline evaluation, parametric surface operations, or spatial indexing for geometric queries. Experience with ACIS, Parasolid, or OpenCascade is a strong signal. Huge bonus if you understand GD&T, tolerancing, or model-based definition well enough to implement it, not just read a drawing. The intersection of manufacturing domain knowledge and C++ engineering skill is exactly what we're building for. Small team, early stage. Every engineer has real influence over architecture and technical direction. This is also a customer-facing role: you'll participate in demos and technical conversations with enterprise customers, so communication skills matter. Requirements: modern C++ (C++17/20), US citizenship (required for government CUI work). $95K–$125K base + performance bonuses, health insurance, 401k match, home office budget, professional development budget. Fully remote, US time zones. jobs@rubypoint.io
