The Sr. Signal Integrity Engineer - Serdes, Satellites (Starlink) joins the Payload Engineering team to provide signal and power integrity ownership for hardware enabling broadband internet connectivity. This role involves managing the full product life-cycle, from early silicon architecture IP evaluation and stackup material selection to PCB layout oversight, troubleshooting, and qualification. You will specify, simulate, and verify advanced satellite hardware, including wireline and electro-optical communication systems with 10 to 112+ Gbps SERDES, DSPs, and high-bandwidth memory interfaces like DDR4 and LPDDR5. Key responsibilities include designing power delivery networks for ASICs and defining simulation workflows. Required expertise includes 3D EM simulation tools such as CST, HFSS, or ADS, along with proficiency in Python and C/C++ to solve complex high-speed digital design and power integrity challenges.
Specify, design, simulate, and verify SI and PI aspects of advanced satellite hardware.
Architect and optimize high-speed wireline communication systems and memory interfaces.
Design and optimize power delivery networks (PDNs) for associated ASICs.
Derive top-level specifications for PCB materials and channel subcomponents.
Root cause and fix issues found in PCB manufacturing, PCBA test, or satellite integration.
Define simulation workflows, test methodologies, and signoff criteria for satellite payloads.
Perform package performance evaluation and stackup material characterization during the design cycle.
What we're looking for
Bachelor’s degree in electrical engineering, computer engineering, or physics.
5+ years of industry experience designing circuits, electronic products, or hardware.
2+ years of experience using 3D EM simulation tools and high-speed digital channel simulators like CST, HFSS, or ADS.
2+ years of research or industry experience with high-speed digital design or power integrity.
Master’s degree or PhD in electrical engineering or computer engineering with emphasis in electromagnetic theory, transmission line theory, wireline transceivers, or power integrity (preferred).
5+ years of experience designing hardware from concept through production with a focus on full life-cycle development (preferred).
5+ years of experience architecting, implementing, and debugging cutting-edge DSP based SERDES products (preferred).
U.S. citizen, national, lawful permanent resident, refugee, asylee, or eligible to obtain required authorizations from the U.S. Department of State.
