Job Description

The 4G/5G/RF Engineer (officially titled Wireless Systems Research Engineer III, IV, or Senior I) works under general direction to manage the department's internal wireless network systems while conducting and supporting basic and applied research in wireless technologies.

This role leverages a strong understanding of existing wireless networks to design, implement, integrate, troubleshoot, and test creative and innovative solutions to emerging challenges in next-generation wireless communications. Areas of focus include:

• 4G/5G wireless network
• Radio access network (RAN) systems (including O-RAN)
• RF fundamentals
• Device-to-Device (D2D) communications
• Vehicle-to-Everything (V2X) communications
• Non-Terrestrial Networks (NTN)
• Cognitive Radio and intelligent wireless systems

This is more than an opportunity to study emerging wireless technologies-it is an opportunity to design, deploy, test, and research them in a real-world environment.

We don't just read about the future of wireless communications. We build and test it.
