Optical Test Engineer at Covesion Ltd.

January, 2023: The successful candidate will join Covesion’s Delivery Team and will undertake assembly and characterisation of waveguides, waveguide modules, and other optical components and systems.  Working in an applied production/research environment producing PPLN devices for commercial sales, the primary responsibility of the role is to assist with optical production and quality assurance of the devices prior to customer shipping. 

Contribution to some areas of our research and development activities will also be required.  The role holder will be work within a production optical characterisation facility which includes optics and sources on the bench scale within a controlled test environment. Although primarily an optical test and assembly role, additional familiarity associated processes such as cleaning, dicing and polishing optical chips will be an advantage, however training can be given in this area if necessary.  Some general administration will be required as part of the role.
