## Job description

About Lumafield:

Lumafield was founded in 2019 to upgrade manufacturing.

We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.

Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.

We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.

Lumafield is headquartered in San Francisco, CA. and has an office in Cambridge, MA.

- Document part and assembly issues, required reworks, and machine configurations for performance traceability
- Provide feedback for improved work instructions and problems found in the manufacturing process
- Test X-ray sources in a Manufacturing Test Bed according to work instructions
- Experience with Hipot and ground continuity testing
- Perform overhead lifting operations using vacuum lifters and gantry cranes, fork lift with provided training
- Crate large scale capital equipment according to work instructions

About you:

- Flexible, Hands-on worker with  strong organizational skills, attention to detail, and ability to work effectively in a team environment
