Digital RF Systems Engineer, DBF Platform SW

Digital RF Systems Engineer

Project Kuiper is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. Come work at Amazon! The role: 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. As a Digital RF Systems Engineer, 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. In this role you will:

• Design, model, and test DSP algorithms such as beamforming, MIMO, DPD, CFR, digital cancellation schemes and RF impairment compensation
• Model RF transceivers impairments and develop RF impairment compensation and testing algorithms. Collaborate with RTL/RFIC designers, communication systems and software engineers to drive chip and system specifications.
• Develop and optimize HW/SW calibration algorithms for RF SOC and phased array systems. Architect HW and FW partitioning of calibration algorithms.
• Develop detailed test plans and test procedures for pre-silicon, help with design verification as well as post silicon validation, integration and characterization of RF Wireless SOC performance. Involve in chip bring-up in the lab and optimize conducted and/or OTA throughput performances by collaboratively working with cross functional teams.
