About Seurat

Seurat is transforming manufacturing for people and our planet by delivering a scalable additive manufacturing solution to fundamentally change how products are made. Seurat’s proprietary Area Printing process, developed at Lawrence Livermore National Labs (LLNL), allows metal components to be manufactured at price points and quality levels that compete directly with conventional manufacturing techniques, enabling the reshoring of supply chains and promoting the decarbonization of industry. Seurat has raised over $180M and is backed by leading venture partners like Capricorn, NVentures (NVIDIA), True Ventures, General Motors Ventures, Denso, Porsche SE, SIP global partners, Honda, Xerox Ventures/Myriad Venture Partners, Cubit Capital, Siemens Energy, and Maniv Mobility.

Seurat Print Processing Software Team

As a foundation member of Seurat’s print processing software team, you, along with a small team of software developers, will architect Seurat’s proprietary suite of browser-based metal 3D printer software applications. Our teams’ mission is to develop tools to unify preprocessing analysis, integrate seamlessly with the next generation of Area Printers, and enable world-class end-to-end service to our customers. Team members work closely and collaborate frequently with engineers across multiple technical disciplines to create innovative designs, products, and services.

Senior Software Engineer (Computational Geometry)

As a senior computational geometry software engineer, you will have a key role in developing the preprocessing software architecture for our metal 3D Area Printing production system applying computational geometry and software development concepts. You will be responsible for designing, developing, and integrating core applications for CAD geometry preprocessing, including feature detection, slicing, layer generation, tile position generation, tile sequencing, engineering analysis, print process simulation, support generation, optimization and generative design for area printing, and machine learning / AI integration.
