Senior Wireless Communications Systems Engineer

E-Space•Arlington, TX

49d•Onsite

About The Position

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. Weâre intentional, weâre unapologetically curious and weâre 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life. As a Senior Wireless Communication Systems Engineer, you will be responsible for modeling, simulating, and designing the physical layer modem for a LEO satellite constellation communication network. This role is critical for ensuring reliable and efficient data transmission in advanced satellite communication systems. In this role, you will leverage your expertise in system analysis, modem design, including time/frequency unite, FEC design, modulator, and demodulator in an advanced wireless communication system. This position will report to the Sr. Director of Product and System Integration, Silicon and you will work closely with systems, software, hardware, and test teams that are responsible for delivering the communications payload. This position is based in our Arlington, TX office.
