3D Geometry Engineer (C++ / Mesh Processing)

We are building a digital orthodontics platform with interactive browser-based 3D tools.
This role is primarily focused on backend 3D geometry and mesh processing with modern C++, with backend and cloud integration as a secondary responsibility. You will build tools for processing complex 3D meshes and integrate them with services used by our web application.

You Are
Strong in modern C++17 or later.
Have commercial experience with computational geometry, mesh processing, CAD, medical 3D, 3D printing, or similar systems.
Understand triangle meshes, topology, normals, boundaries, non-manifold geometry, and numerical tolerances.
Have worked with mesh operations such as repair, remeshing, simplification, cutting, Boolean operations, offsets, or registration.
Have practical experience with at least one geometry-processing library or SDK.
Comfortable with linear algebra and spatial data structures such as BVH or k-d trees.
Experienced with CMake, Linux, Docker, profiling, and native dependency management.
Able to write tests for geometry code using fixtures, invariants, and tolerance checks.
Comfortable integrating native C++ code with backend services through a CLI, library, binding, or containerized worker.
Familiar with Git workflows, pull requests, and code review.

Will Be a Plus
Experience with Node.js, TypeScript, or Python.
Experience with C++ bindings such as pybind11 or nanobind.
Familiarity with Three.js, WebGL, or browser-based 3D viewers.
Experience with AWS or another cloud platform.
Experience with asynchronous processing and object storage.
Background in medtech, healthcare, scientific visualization, or 3D printing.
Familiarity with AI-assisted development tools such as Cursor, Claude Code, or Codex.

What We Expect from You
Own geometry features from implementation to production integration.
Make practical engineering decisions without unnecessary overengineering.
Define clear quality checks and tolerances for geometry operations.
Proactively identify performance, memory, and geometry-quality issues.
Be comfortable working in an evolving product with changing priorities.
Collaborate effectively with backend and frontend 3D engineers.
Review, test, and validate AI-generated code before delivery.

Responsibilities
Build and improve native C++ mesh-processing tools and libraries.
Implement and integrate geometry-processing algorithms.
Package geometry operations as reliable headless Linux workers.
Integrate native processing with backend services and cloud workflows.
Define clear inputs, outputs, and structured error reporting.
Optimize processing time, memory usage, and output mesh quality.
Write unit, integration, and regression tests for geometry operations.
Collaborate with Three.js developers on mesh formats, units, coordinate systems, and transforms.
Participate in technical design discussions and code reviews.
Use AI-assisted development tools responsibly and contribute to engineering best practices.

What We Offer
Work on an innovative product in the medical-tech and 3D geometry domain.
High ownership and direct impact on technical decisions.
Flexible working hours within the European time zone.
Fully remote, full-time, long-term cooperation.
A fast-moving environment where strong engineers can influence the product and architecture.
Company-paid premium AI development tools.
Professional development support, including courses and certifications.
20 paid business days of vacation.
5 paid sick-leave days.
Paid national holidays.
