Summary for Senior RF & Electromagnetic Engineer  

At Optisys this senior engineer will be working with the latest technology everyday. Some people call it magic.

We are looking for an antenna designer who designs antenna components with waveguide technology.

We prefer an expertise in HFSS with recent experience OR an expertise in CST with HFSS experience. 

This role is for an individual who is open to additional learning and would relish the opportunity to immerse themselves in both project work and deeper RF theory to support our extensive IRAD activities.

This is a new role, due to the exponential increase in design work, specifically in electromagnetic antenna design. The successful candidate will directly report to the CTO, Michael Hollenbeck.

The preference is for this role is to work at the Optisys HQ in Salt Lake, to support the day to day running of projects and production, however, part/full time remote working would be considered.

This role is an opportunity to work on the leading edge of metal 3D printed antennas, which are a novel class of antennas that allow for pushing the limits of what physics allows in antenna design. Optisys antennas can be found all around the world and out of this world in space. This position requires creativity and exploration of difficult design challenges to solve problems that have not been encountered before.

Duties and Responsibilities 

Design antenna components and systems to customer requirements on a variety of platforms and environments.

Work primarily in ANSYS HFSS to design, model, and optimize highly integrated antenna assemblies all the way from single components up through multi-thousand component assemblies.

Work closely with Mechanical and Additive Manufacturing engineers to understand the rules for design using Optisys’ proprietary fabrication techniques.

Interact directly with customers to provide updates on program status and reviews.

Be able to independently solve challenging problems that do not have easy answers.

Create novel structures and designs that provide unique RF function.
