Optical Systems Engineer
Lausanne, Switzerland
vor 8 Std.

ViaSat builds high-capacity satellite networks across the world, challenging the notion that broadband connectivity only happens on terrestrial networks.

To keep up with growing broadband demand we are continuously innovating in all the components of a satcom system, from the ground segment, the satellite and the user terminals.

The engineering group in Lausanne is involved in many innovation activities that require a system vision and an advanced understanding of radiocommunication systems and signal processing.

In particular for this position we are looking also at knowhow and experience in the field of optical communication and photonics integration technology.

Job Responsibilities

As an Optical Engineer, you'll collaborate with the innovation / engineering team from various Viasat locations to brainstorm and design innovative communication systems potentially applicable to our future satellites.

The work will encompass also the design of testbeds to validate design assumptions and variations. In this role you will deal with system conception driven by the optimization of the full satcom chain with respect to major parameters like performances, cost, power consumption and system complexity on ground and in space.

You will also contribute to build analysis tool to perform analysis and trade-offs.

We encourage learning through osmosis, ensuring no one is confined to their specific area of work. Similarly, we value ability and willingness to learn, over experience in a particular area.

This isn't to say we don't value expertise and mastery of a subject, rather we recognize the need for evolution of knowledge in our rapidly changing field.

We are looking for individuals who are excited by challenging problems and love to dive into new technologies to solve them.
