Staff Computational Engineer, 3D CAD

Xometry is seeking a highly skilled Staff Computational Engineer with a strong background processing three-dimensional models to help create the next generation of automated design for manufacturing (DFM) tools. In this role, you will analyze three-dimensional models for manufacturing feasibility and risk by combining underlying features with real world manufacturing constraints. This role requires someone with a strong understanding of computational geometry, algorithm analysis and code design.

Responsibilities:

• Design, develop, and implement computational algorithms to solve complex engineering problems related to manufacturing processes (e.g., quoting, optimization, quality control).


• Design, develop and deploy algorithms to extract geometric features from 2D and 3D CAD models.


• Design, develop and deploy algorithms to detect Design for Manufacturability (DFM) issues of 2D and 3D CAD models.


• Identify practical solutions to problems involving 2D and 3D geometry, topology, numerical analysis, manipulation of curves, surfaces and boundary representation topology.


• Leverage machine learning and artificial intelligence techniques to improve efficiency and decision-making within the manufacturing platform.


• Collaborate with operations and product teams to understand critical issues and develop novel solutions.


• Collaborate with data scientists and software engineers to integrate computational solutions into Xometry's production workflows.


• Document code and algorithms for maintainability and knowledge sharing.


• Stay up-to-date on the latest advancements in computational engineering and related fields.

Requirements:

• M.S. or PhD degree in applied math, physics, computer science, or engineering required.


• 8+ years of progressive experience in applying computational methods to solve engineering problems with a proven track record of success.


• Demonstrated experience in using CAD/CAE systems: surface modeling, solid modeling, part/assembly modeling, drafting.


• Demonstrated experience in developing geometric modeling kernel, especially working with analytical geometry, parametric modeling,  freeform geometry (NURBS, spline surfaces, Bézier curves), topological data structures (B-Rep scheme), geometry healing and repair, high-performance data structures and algorithms.


• Participation in the development of 3D modeling applications, like SolidEdge, SmartPlant3D, SurfaceWorks, Autodesk Inventor, Pro-Engineer, SolidWorks, ACIS is a plus.


• Demonstrated experience with HOOPS Exchange API, PRC and DXF format and specifications.


• Research experience in computational geometry, differential geometry, computational fabrication, computational dynamics, or related fields.


• Proficient in linear algebra, multivariable calculus, numerical methods, differential equations and other areas of scientific computation, like floating point arithmetic and numerical error analysis.


• Familiarity with industry-specific standards (e.g., ISO, ASME) and guidelines for CAD/CAE software.


• Strong knowledge of manufacturing processes and materials science.


• Fluent in C++ (C++11/14/17), including tools like CMake, GDB, SWIG, etc.


• Experience in Python, Cython, numpy, numba and cloud computing platforms a plus


• Proficiency in software engineering best practices, including object-oriented design, code versioning, and testing.


• Strong documentation skills for developing user manuals, technical reports, and internal documentation to support maintainability and reproducibility.


• Must be a US Citizen or Green Card holder (ITAR).
