Sr. System Development Engineer, Antenna System Validation

Amazon Leo is a long-term Amazon program to increase global broadband access through a constellation of satellites in Low Earth Orbit (LEO); providing low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. Direct-to-Device (D2D) is Leo's initiative to enable standard smartphones and IoT devices to connect directly to satellites, filling coverage gaps in remote areas. As a System Development Engineer, you will design and develop hardware, firmware, and/or software solutions for antenna systems supporting both our current production satellites and new programs including D2D and our next-generation satellite constellation. You'll work closely with hardware, RF, and software teams to bring up, test, and ship systems that combine custom hardware, FPGAs, and embedded firmware and see your work in the lab or in orbit. Export Control Requirement: 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 - Own design and implementation of hardware, firmware, software, or FPGA components for antenna systems - Collaborate with systems architects and cross-functional hardware, firmware, and software teams to define, implement, test, and release new antenna hardware and software capabilities - Support bring-up, characterization, and validation of antenna subsystems in the lab and on test hardware - Troubleshoot and resolve hardware, firmware, and software issues found during development, integration, or production testing - Contribute to design reviews and technical documentation for new hardware, firmware, and software A day in the life Most days, you're working with cross-functional teams talking through requirements with antenna and hardware engineers, sketching out designs, and writing documentation others will rely on. Some days you're in the lab instead, hands on the hardware.

Our team validates payload phased arrays. The antennas we work with are packed with many processors and hundreds/thousands of individual elements working in sync. We test designs, find what breaks, and build the tools that make that possible. We partner closely with antenna, hardware, and firmware engineers. We take pride in catching problems before launch since once it's in orbit, there's no fixing it by hand.
