Optical Systems Engineer - Optical Transmission

Molex possesses a rich heritage in the optical industry.

We provide the highest performing and field-proven optical solutions from components, modules to integrated line-cards.

We provide cutting edge wavelength management and amplifier technologies.

Our comprehensive optical, mechanical, electrical and software integration capabilities enable us to serve the needs of high-density, high-bandwidth, and flexible optical networks.

Our team in Fremont is hiring an Optical System Engineer to join our optical transmission team.

We develop cutting edge network components and modules, such as high speed Optical Transceivers, DWDM/WDM Filters, Optical Amplifiers, Raman Amplifiers, Dynamic Gain Equalizer (DGE) and Wavelength Selective Switch (WSS).

In this role, the Engineer will be responsible for developing optical transmission system and sub-system simulations and define inputs for system design and performing system validation.

The engineer will build and manage system test beds and support customer needs throughout the development process.

The main focus of the role will be development optical transition system simulations and work with colleagues in various geographic sites to develop optical network products that meet our customers needs.
