Job Summary

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.
