Job Summary:
The Senior Software Engineer will contribute to the development of 3

DEOs proprietary slicing engine and the end-to-end software platform that powers our metal 3D printing process. This role focuses on geometry processing, toolpath generation, and digital workflows used across our vertically integrated production system. Ideal candidates have experience building slicers, simulation tools, or manufacturing automation software and enjoy working at the intersection of software and hardware in a fast-moving RD environment.

Essential Functions:

● Develop and maintain core slicing algorithms including path planning, infill generation, and motion logic

● Implement and optimize geometry processing tools (mesh repair, offsetting, tessellation, Boolean ops)

● Contribute to the architecture of the internal production platform, including job tracking and printer interfacing

● Integrate slicing logic with upstream and downstream systems including UI, hardware control, and analytics

● Collaborate closely with mechanical, controls, and process engineers to translate physical constraints into software rules

● Write clean, well-documented, and testable code to support scalable manufacturing

● Participate in code reviews and technical design discussions

Required Qualifications:

● Strong programming skills in C++, Rust, or Python

● Experience with computational geometry, 3D data structures, or mesh processing

● Familiarity with additive manufacturing tool chains or CNC-style toolpath generation

● Ability to work in a cross-functional RD environment with hardware and process teams

● Comfortable building production-grade software in a fast-paced, iterative setting

● Experience with continuous integration (CI) pipelines, static code analysis, and unit testing

Preferred Qualifications:

● Experience with industry standard or related geometry engines/libraries

● Familiarity with motion control systems, G-code generation, or machine integration protocols

● Background in data pipelines or job tracking for manufacturing operations

● Prior work on metal additive manufacturing or CNC-based systems

Education and Experience:

● Bachelors degree in Computer Science, Software Engineering, or related technical field required

● 5+ years of experience in software development, with at least 12 years in a manufacturing, robotics, or 3D graphics setting

● Open-source contributions to slicing software or experience building AM/CAM tool chains is a plus

Physical Requirements and Work Environment:

● Primarily office/lab-based with some machine interaction

● Must be able to occasionally inspect physical parts or collaborate with operators near equipment
