Optical Imaging Engineer Job Descriptions, Average Salary, Interview Questions

Optical engineers are responsible for the research, design, and testing of devices that use cameras, lasers, microscopes, and refractometers. The devices they design and test are found in many of our modern technologies, including smartphones and computers. They control and manipulate light to use in high-tech devices. Optical imaging engineers work in agriculture, aerospace, lighting, textiles, and design. They design devices used in scientific instruments or optomechanical equipment. Some work with observatories, maintaining telescopes and other astronomical instruments. Optical imaging engineers must have excellent written and verbal communication skills as they write and communicate detailed procedures for operations and equipment use. 

Optical imaging engineers should have in-depth knowledge of the properties of light and optics, and a strong background in mathematics and physics as pertains to light and refraction. Exceptional problem-solving abilities and excellent working knowledge of relevant software programs, such as MATLAB, CAD, GIS, DFMA, R Language, and C are crucial for this position. Optical imaging engineers need to stay current on new trends, technologies, and innovations regarding the principles of light.
