OPTO-MECHANICAL BUILD ENGINEER
Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits.
In this role, you will be responsible for leading the development and deployment of custom opto-mechanical systems for the world’s most advanced metal 3D printing systems. You will establish and scale processes for how we build, assemble, align, and integrate opto-mechanical systems. You will work with high-power lasers, high-speed cameras, and other proprietary hardware and software to integrate novel capabilities. This is a hands-on role in which you will be expected to own hardware development, testing, and implementation yourself. Opto-mechanical systems lie at the heart of our technology, so this is a high-impact opportunity at a rapidly growing deep-tech company.
3D printing experience is not required to be successful here - rather we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology!
Responsibilities:
- Build, assemble, align, and deploy complex opto-mechanical systems.
- Develop procedures for scaling in-house opto-mechanical build processes from prototype to volume production.
- Integrate high power lasers and high-speed camera solutions.
- Design mechanical solutions to integrate optical design with precision and repeatability.
- Create drawings specifically to opto-mechanical GD&T standards.
- Establish and own the precision alignment process including method, procedure, and software used.
- Perform test and characterization of optical performance including process, equipment selection, and passing criteria.
- Work closely with process engineering team to solve physics-based interdependencies.
- Work closely with mechanical, electrical, and software engineering teams to develop a robust and scalable system architecture.
Basic Qualifications:
- Bachelor’s degree in Optics/Optical Engineering, Mechanical Engineering, or Physics, and 2 years of hands-on professional experience; or a Master's degree in one of these disciplines and at least one hands-on opto-mechanical internship.
- Hands-on experience with opto-mechanical systems (build, assembly, alignment, etc.).
- CAD experience, including GD&T and detailed drawing documentation as it relates to opto-mechanics.
- Strong mechanical engineering and physics fundamentals.
Nice to Have:
- Master’s degree in optical engineering or mechanical engineering.
