Sr. Power Electronics Engineer, Amazon Leo Customer Terminal

Amazon Leo 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. On the CT Power Team, you will design the power delivery systems enabling the next-generation Amazon Leo Customer Terminal portfolio.

About the role

You'll own point-of-load regulator design, power distribution network (PDN) analysis, and converter development for products that span high-volume consumer terminals and low-volume high-performance platforms. Your designs go from simulation to bench to production.

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.

Responsibilities

• Own power delivery design end to end: regulator selection, PDN design, control loop compensation, prototype build, characterization, and validation.
• Lead power architecture trades that balance efficiency, cost, thermal, and performance across both high-volume/cost-sensitive and low-volume/high-performance designs. Your recommendations determine what gets built.
• Perform DC drop and AC PDN impedance analysis. Define decoupling strategies, remote sensing solutions, and validate power delivery meets Silicon requirements.
• Collaborate with Silicon teams to track power budgets, model power system needs, and ensure the PDN supports all terminal use cases.
• Design, simulate, and build prototype converters and power systems. When something doesn't behave, get to the bottom of it and fix it.
• Own power telemetry solutions and their digital interfaces (I2C, PMBUS, SPI).
• Lead design reviews and set the technical bar for power delivery across terminal products.
• Work closely with silicon, RF, antenna, thermal, mechanical, and systems teams to close budgets and solve problems within real-world constraints.

Requirements

• Bachelor's degree in Electrical Engineering or related field.
• 5+ years of experience designing linear and switching DC-DC Converters for SOC/ASIC/CPU applications.
• Experience with PDN analysis tools (Sigrity, Ansys SIwave, or similar).
• Experience with measurement and debugging of power electronics and PDNs.
• Experience taking power electronics from concept through production.
• Experience in developing functional specifications, design verification plans, and functional test procedures.

Preferred Qualifications

• Master's degree in electrical engineering, computer engineering, or equivalent.
• Experience working with interdisciplinary teams to execute product design from concept to production.
• SI/PI co-simulation experience for mixed signal applications.
• Experience designing power systems for custom ASICs or SoCs.
• Experience designing products to meet EMI/EMC standards.
