We're partnering with a global construction technology company building a leading platform used by owners, contractors, and engineers to plan, design, and build construction projects worldwide. Our Product & Technology organization spans engineering, product, design, data, and security — all working to modernize one of the world's largest, most under-digitized industries.

This role sits within BIM (Building Information Modeling) Engineering team, which owns the pipeline that brings 3D construction models from tools like Revit, Navisworks, and IFC-based authoring software into our platform, and powers the fast, in-browser 3D viewing and coordination experience our customers rely on daily.

We're looking for a senior engineer to join our BIM Engineering team, focused on the geometry and data-processing layer that converts industry-standard CAD/BIM file formats into our internal 3D scene representation. This is deep, specialized work: you'll be responsible for parsing, translating, and optimizing complex 3D construction data so it renders quickly and accurately for our customers, at scale.

You'll act in a senior technical capacity leading complex projects, setting technical direction, and mentoring other engineers, while partnering closely with Product, Design, and adjacent engineering teams (platform infrastructure and 3D viewer/rendering) to ship features built on cutting-edge BIM 3D technology.

• Build and maintain parsers and data-processing pipelines that convert industry file formats (e.g. IFC, RVT, DGN) into our internal geometry and scene format

• Work on geometry processing problems spanning parametric CAD data, point clouds/scans, and GIS data

• Establish engineering standards and best practices across development teams; collaborate with infrastructure and platform teams on shared architecture

• Help design and build systems aligned with a service-oriented architecture, supporting both enterprise and international customer needs

• Collaborate cross-functionally with Engineering, Product, and UX to design solutions that solve real customer problems

• Mentor other engineers reviewing designs and code, and helping the team consistently ship high-quality software

• Diagnose and resolve data-fidelity issues (e.g. geometry or metadata discrepancies) reported by customers, tracing them through the parsing/processing pipeline

• Contribute to safe, incremental rollout of changes to production data-processing systems, with attention to backward compatibility and rollback safety

• Bachelor's degree in Computer Science or a related field, or equivalent practical experience

• Professional software development experience with 5+ YOE and with strong proficiency in C++

• Experience with geometric modeling parametric curves and surfaces (splines/NURBS)

• Experience handling engineering/CAD data, and ideally exposure to laser scan/photogrammetry or GIS data

• Familiarity with common **3D/CAD file formats**: IFC, RVT, DGN, glTF, or similar

• Experience with relevant libraries/SDKs, such as: Open Cascade, Assimp, Open Design Alliance (ODA), MeshLab, or GDAL

Nice to have:

• Experience with Rust

• Background in 3D rendering and real-time rasterization techniques (PBR, IBL)

• Familiarity with spatial acceleration structures (BVH, K-d tree, octree)

• Experience with 3D graphics techniques: triangle meshes, BREP, point clouds, level-of-detail (LOD), mesh decimation/simplification, mesh cleanup and optimization

• Exposure to hardware-accelerated ray tracing (e.g. Nvidia OptiX, DX12)
