Sr Power Electronics Engineer, Amazon Leo Government (ALG)

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.

The mission of Amazon Leo Government (ALG) team is to leverage existing Kuiper technology and provide high speed, low latency, and secure satellite broadband services to the United States and our allied government customers.

The Senior Power Electronics Engineer will play a pivotal role in the team delivering innovative and fast-paced analysis and design solutions, focusing on satellite and ground system design and analysis as well as on the design of the various communication and control needs (compute, storage, data transfer, etc.) of the power electronics sub-systems. They will be expected to lead a variety of tasks, from schematic design and component selection, circuit analysis and simulation, to layout review and board bring-up and test. They will work across teams and support fellow engineers with design reviews and the preparation of joint reports and proposals. The candidate will have a sharp focus on the specific needs of the customer and be able to conduct trades and analyses to show that proposed solutions will meet the customer's goals.

The successful candidate will have demonstrated experience working on complex programs with a diverse set of talented individuals, as well as with partner organizations (including government agencies). The candidate will exhibit the potential to lead small sub-teams of electrical engineers, and be able to prepare easy-to-read and technically compelling written reports.

"This position requires that the candidate selected be a U.S. Citizen in order to comply with U.S. government-imposed requirements related to the nature of the work and/or where it will be performed."

Key job responsibilities

• Interact directly with customers to understand technical requirements, and translate them into technically robust solutions backed by data and analysis.
• Responsible for electrical power circuit design (including digital and analog power) for hosting sensitive RF and communications payloads including processing, memory, and communication buses.
• Strong technical background and work experience designing electronic circuits including Analog Power circuits for power and delivery with filtering, voltage/current protection, and IR drop considerations.
• Experience designing both isolated and non-isolated power conversion circuits with multiple energy storage (inductor, transformer, etc) topologies.
• Strong technical background and work experience designing electronic circuits including switch mode power supplies (SMPS), buck/boost converter, linear regulators, AC/DC and DC/DC converters.
• Design using different DC/DC converter topologies including: buck, boost, flyback, current-mode, voltage-mode and various feedback mechanisms.
• Analyze designed circuits using software tools for performance and characterization including Power Integrity (PI) and Power Distribution Networks (PDN) on fabricated Printed Circuit Board (PCB) designs.
• Identify top level customer requirements and ensure high quality and innovative designs are pursued.
• Perform electrical design and layout trade studies for electrical and power sub-systems contributing to overall system architecture including inputs and requirements from cross discipline teams.
• Facilitate cost trades on multiple parallel configurations for cost/manufacturability vs design uncertainty.
• Deliver well-written documentation, reports, and presentations for technical design reviews and as part of proposal efforts.
• Design and support test campaigns, both development and qualification/acceptance, for space hardware.
• This position requires the candidate be a US Citizen.
