Senior Software Engineer, CAD Interoperability

Zoo is building the next generation of hardware design tools redefining how hardware products are designed, developed, and built. We are seeking a Senior Software Engineer, CAD Interoperability, to help build systems that convert CAD formats into Zoo's KCL, focusing on CAD data extraction and geometry processing.

Responsibilities:

• Design, implement, and maintain import pipelines that convert native and proprietary CAD formats into Zoo's KCL
• Build systems for extracting feature information from CAD files and applications, including sketches, dimensions, constraints, parameters, feature trees, assemblies, metadata, PMI, and related design intent
• Develop extractors using native CAD application APIs and toolkits where interoperability SDKs are insufficient
• Translate extracted CAD structure, geometry, parameters, and feature information into KCL that faithfully represents the original model
• Build validation, testing, and comparison tools to measure conversion quality across geometry, topology, feature information, assemblies, and generated KCL output
• Handle edge cases across proprietary formats, CAD versions, modeling kernels, malformed files, incomplete metadata, and inconsistent vendor API behavior
• Collaborate with the file format, modeling, and product teams to improve Zoo's CAD import experience and expand support for real-world customer files

Requirements:

• B.S. in Computer Science, Mechanical Engineering, or a related field, or equivalent experience
• Strong professional experience in software engineering, ideally involving CAD, geometry, file formats, code generation, or data extraction systems
• Experience working with complex technical data formats, application APIs, SDKs, or translation pipelines
• Proficiency in a systems programming language such as Rust or C++, with comfort working across language boundaries and vendor SDKs
• Experience building automated tests, validation tools, and debugging workflows for complex technical systems
• Ability to work autonomously, investigate unfamiliar systems, and make pragmatic technical decisions in a fast-moving environment
• Strong understanding of CAD model structure, including parts, assemblies, sketches, constraints, dimensions, features, parameters, B-rep geometry, and tessellated representations
• Experience with CAD interoperability SDKs such as HOOPS Exchange, CoreTechnologie 3D_Kernel_IO, Open Design Alliance, CAD Exchanger, Datakit, or similar tools
• Experience with native CAD APIs such as SOLIDWORKS API, Creo TOOLKIT, NX Open, CATIA CAA/API, Inventor API, or similar
• Experience with STEP, IGES, Parasolid, ACIS, JT, glTF, STL, or other CAD and 3D exchange formats
• Experience generating structured source code from model data, especially for DSLs or domain-specific modeling languages
• Familiarity with KCL or other programmatic CAD workflows
