Optical Engineer
Apply physics principles to design reliable systems and products.
What is an Optical Engineer?
Optical engineers design, develop, and test optical components and systems, such as lenses, mirrors, fiber optics, lasers, and imaging devices. They apply principles of physics, particularly optics and electromagnetism, to create solutions for a wide range of industries including telecommunications, medical devices, manufacturing, and defense.
You spend days in environmentally controlled labs designing and integrating imaging and electro‑optical sensing systems: choosing components, running targeted tests to establish functionality and limits, and documenting design processes. Work is collaborative — face‑to‑face planning, emails, and team integration — and alternates between prototype experiments and gradual adaptation toward production readiness.
