Antenna Design Engineer

Job Description

Description

This engineering position supports the Survivability Solutions branch within the Advanced Sensing and Emerging Technologies division at Leidos Innovations Center (LInC) based in San Diego, CA.

As a member of the Survivability Solutions branch you will collaborate with a multi-discipline team to cultivate high impact discriminating solutions for our growing customer base ranging from concept development, rapid prototyping, laboratory and field testing, and final integration. Our cross-functional team offers many opportunities for skillset development across a range of technologies in a fast-paced environment that rewards technical creativity and applied theoretical knowledge of mechanical, electrical, and RF engineering concepts.

Primary Responsibilities :

• Hands-on design and realization of both front and back-end antenna systems and integration focused on individual antennas, phased antennas, RF circuits, passive RF components, and RF systems.
• Use of computational electromagnetic software to design and predict performance on various types of antennas and apertures (HFSS, COMSOL, FEKO, SENTRI, CST, etc.).
• Development of antenna link budgets to define system requirements, estimate expected gain and losses over bandwidth, determine operating link margin, and performing optimizations in consideration of project constraints.
• Design and integration of frequency selective surfaces (FSS) for use with a variety of radomes and radiating aperture designs.
• Low observable design implementing various techniques including materials, shaping, etc. for RCS mitigation where necessary.
• Investigation of new technologies and applications for radiating apertures, antennas, and RF systems.
• RF hardware testing of required performance metrics : VSWR, insertion loss, gain, polarization, radar cross-section (RCS), etc.
• Collaboration with a multi-disciplinary team to perform requirement evaluation, initial concept trade studies, in-house and customer presentations.
• Provide technical input to support proposals and new business opportunities.
• Provide direct engineering support for customers to end-users.

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
