## Description

The software team is part of the Global Manufacturing Engineering (GME). Alongside GME's Hardware Controls, Manufacturing Process, and Automated Quality Control teams, we build the geometrical compiler behind Spark Clear Aligners: the math-heavy software stack that turns digital treatment intent into physical parts at production scale. Our systems decide how geometry gets transformed, nested, validated, and translated into instructions that run across a global factory footprint producing more than 100,000 unique parts per day., We are hiring a 3D C++ Software Engineer with a strong foundation in applied mathematics, computational geometry, and software engineering. You will contribute to the design, implementation, testing, and support of software systems that bridge CAD to CAM, including geometry processing, numerical optimization, manufacturing workflows, and production automation.

You should be comfortable working through mathematical and engineering problems, implementing robust solutions in modern C++, and collaborating with senior engineers, R&D teams, and manufacturing stakeholders to validate those solutions on real hardware.

This is a full-time and on-site five days/week engineering role in Pomona, CA. Rapid development here depends on being next to the hardware and the people using it. You will work directly with R&D equipment such as scanners, 3D printers, CNC systems, and metrology tools, shortening the loop between idea, code, experiment, measurement, and revision from weeks to days., * Develop and maintain algorithms for 3D geometry processing, CAD/CAM workflows, spatial reasoning, and numerical computation within a production manufacturing environment.

 * Support the implementation of computational models that represent physical processes, machine constraints, and manufacturing requirements.
 * Write high-quality C++20 code with attention to correctness, maintainability, performance, and reliability.
 * Prototype and evaluate ideas using Python, NumPy, SciPy, and related tools when appropriate.
 * Collaborate closely with R&D, Manufacturing Engineering, and Operations teams to test software on production and laboratory equipment.
 * Participate in the validation and troubleshooting of software systems by analyzing outputs, identifying root causes, and implementing corrective actions.
 * Contribute to services that utilize gRPC, Protobuf, Bazel, Conan, Docker, and cloud-based deployment environments.
 * Participate in code reviews, technical discussions, and continuous improvement of software engineering practices.
 * Any duties or tasks assigned by Manager.

Examples of the Work:

 * Implement algorithms that identify unsupported geometry in printable parts and assist in generating support structures that improve manufacturing success rates.
 * Develop geometry-processing tools that modify part surfaces, wall thicknesses, and manufacturing features based on engineering requirements.
 * Process and analyze point-cloud or scan data to compare manufactured parts against digital models and identify deviations.
 * Support optimization of CNC or manufacturing process parameters through mathematical modeling and software automation.
