Due to applicable export control laws and regulations candidates must be a U.S. citizen or national U.S. permanent resident (i.e. current Green Card holder) or lawfully admitted into the U.S. as a refugee or granted asylum.
Key job responsibilities
As a Digital RF Systems Engineer working on the DBF Platform Software team you will be implementing validating and testing end-to-end system models including fixed point DSP blocks RF impairments of the radio phased array antenna and satellite channel. You will be involved in novel techniques to estimate and correct RF impairments that will be implemented in HW and FW. Based on the system level constraints such as low power and cost you will develop validation techniques and optimized solutions to support high throughput for our customers.
You will engage with an experienced cross-disciplinary staff to conceive and design innovative product solutions. You will work closely with internal inter-disciplinary teams such as ASIC/RFIC designers FW/SW engineers design verification engineers. You will support validation of the silicon in the lab and optimize RF performance via algorithms.
