About Rubypoint

Rubypoint is building next-generation digital manufacturing technology, backed by major industry partners (including Fortune 500 companies). We’re a small, highly technical team building core technology from the ground up.

About the Role

We’re building a modern, high-performance computational engine in C++20. We’re looking for a strong C++ developer who enjoys algorithms, data structures, and performance-critical work.

We are open to strong C++ engineers without prior CAD/geometry experience. We value raw technical ability and will actively support domain onboarding.

What You’ll Do

Design and implement core algorithms and data structures
Develop performance-critical C++20 components and internal APIs
Work on geometry processing and spatial computation routines
Improve performance: memory layout, cache efficiency, algorithmic optimization
Write clean, well-tested code and contribute to validation tooling

Must-Have

Strong modern C++ (C++17/20)
Strong fundamentals in algorithms & data structures
Experience with non-trivial systems code (performance-sensitive preferred)
Solid debugging skills and a test-driven mindset
Ownership mindset: you can take problems end-to-end

Nice to Have (Bonus)

Computational geometry or graphics experience
Spatial data structures (BVH, kd-trees, grids)
Numerical robustness / floating-point behavior
Any CAD / modeling exposure
Experience with engineering data formats and schemas (e.g., STEP/IGES/JT/STL, XML/XSD)

Why Join

Work on hard, core algorithms in a modern C++20 codebase (no legacy)
Real ownership: influence architecture, APIs, and long-term direction
Small, expert team with direct access to technical leadership
Competitive compensation + performance bonus
Private health insurance
Learning & conference budget
Remote start; transition to in-office collaboration in Belgrade with hybrid flexibility
Collaboration with customers across Europe/US, plus travel to conferences and customer sites
