Job summary

NKT Photonics is seeking an optical engineer to join our team in Denmark. You will support the development, assembly, and test of custom laser systems and optical subsystems, collaborating with senior engineering staff.

The role emphasizes hands-on work with free-space optics and fiber coupling, experience with ultrafast or high-power sources, and using Zemax for optical layouts; you will document experiments and contribute to product transfer.

Qualifications

Background in optical engineering, physics, or closely related discipline.
Hands-on experience with laser systems, ideally including ultrafast and/or high-power CW laser sources.
Understanding of optical modes in fibers and their impact on coupling and system performance.
Hands-on work with free-space optics, including alignment and coupling light into optical fiber.
Optical test and measurement capability, including laser and beam characterization.

Responsibilities

Support the development, assembly, and test of custom laser systems and optical subsystems, working closely with senior engineering staff.
Design and execute experiments to evaluate new laser and optical system concepts and architectures.
Characterize and test laser systems and fiber-optic assemblies to quantify performance and validate designs
Support high-power laser testing of optical assemblies and subsystems
Document experimental setups, test results, and assembly procedures to support product development and transfer
Contribute to the development of optical prescriptions and layouts using optical design tools (e.g., Zemax)
