Vinci4d is building the next-generation copilot for hardware designers and engineers - integrating rich text, image and 3D geometry (STL, OBJ, STEP…) workflows with machine learning, physics modeling, and geometry processing pipelines. Our mission is to dramatically accelerate hardware design through intelligent automation, and we’re looking for a senior engineer in geometry + meshing to help us build the core systems.
As a Senior Geometry / Meshing Engineer, you will lead the design, implementation and optimization of the geometry and mesh-generation systems that underpin our copilot platform. You’ll work at the intersection of computational geometry, mesh generation (surface and volume), numerical methods, GPU/parallel architectures, and largescale geometry data (often millions of points/cells). You’ll collaborate with ML and physics simulation teams, contribute to system architecture, mentor engineers, and ensure our mesh infrastructure meets the needs of our hardware-design workflows.
Architect and implement robust mesh generation and geometry processing pipelines (surface/volume, unstructured/structured, quad/hex/tri/tet) suitable for industrial-scale hardware design.
Develop and optimize algorithms for geometry import, repair, parameterization, mesh refinement/coarsening, adaptation, quality improvement, and mesh ↔ simulation interoperability.
Work with very large geometry/mesh datasets (e.g., tens of millions of points/cells), designing for performance, memory efficiency and GPU/parallel execution.
Interface with CAD/geometry input (STEP, IGES, B-Rep, etc), preprocess geometry for meshing, handle complex topologies, feature preservation, and simulation readiness.
Collaborate with ML, physics, simulation and UI/UX teams to define requirements, integrate mesh generation into the larger system, and deliver high-impact features.
Mentor and lead other engineers: drive best practices, code reviews, algorithmic reviews, and help define roadmap directions for geometry/meshing capabilities.
Engage with strategic customers or internal stakeholders to understand geometry/meshing requirements, performance bottlenecks, and production use-cases.
Maintain high quality: testing, validation, regression frameworks for geometry/mesh generation code; diagnose and fix complex bugs and performance issues.
Bachelor’s (BS) in Computer Science, Applied Mathematics, Computational Geometry, Mechanical/Aerospace Engineering, or related field.
≥ 5 years of professional experience (or a Master’s + 3 yrs, or PhD + 1–2 yrs) in geometry processing, meshing or simulation infrastructure.
Strong software engineering skills in C++ (modern C++ standards) and experience in algorithm design and implementation.
Experience with GPU / CUDA / OpenCL, high performance computing (HPC), multi-threading, distributed computing a plus
Deep understanding of computational geometry, mesh generation techniques (triangulation, tetrahedral meshing, hex/quad meshing, mesh refinement/coarsening) and quality metrics.
Experience working with large geometry/mesh datasets, concerned with performance (CPU/GPU), memory efficiency, parallelism.
Excellent problem-solving, analytical skills, and the ability to collaborate across disciplines (e.g., simulation, ML, CAD/geometry).
Experience with CAD import/export (STEP, IGES, B-Rep), and working with CAD systems or geometry kernels (Parasolid, ACIS, OpenCASCADE).
