Description

As a Senior Research Engineer at 3M, you will have the opportunity to tap into your curiosity and collaborate with some of the most innovative and diverse people around the world.

You will develop new optical inspection and metrology methods for optics-related parts used in advanced product and process applications.

Key responsibilities include:

  • Designing, building, and validating benchtop inspection systems to detect, characterize, and quantify critical defects and quality attributes.
  • Creating inspection approaches for a broad range of defect modes, including scratches, chips, cracks, inclusions, contamination, edge defects, coating defects, cosmetic defects, and dimensional variation.
  • Applying optical engineering, imaging, and machine vision principles to develop robust methods using transmitted light, reflected light, bright field, dark field, polarization, structured illumination, and other contrast mechanisms as appropriate.
  • Developing image acquisition, analysis, and data interpretation workflows to improve defect detection sensitivity, repeatability, and overall method capability.
  • Partnering closely with R&D, process development, product development, quality, manufacturing, and equipment teams to define inspection requirements and translate technical needs into scalable solutions.

The expected compensation range for this position is $124,127 - $151,710, which includes base pay plus variable incentive pay, if eligible.
