Signal Integrity Engineer, Amazon Devices
Amazon Lab126 is an inventive research and development company that designs and engineers high-profile devices like the Kindle family of products. Lab126 began in 2004 as a subsidiary of Amazon.com, Inc. Since then, we have worked to produce best-selling e-readers and tablets, as well as new inventions like the Echo line of products, Fire TV and Fire phone.
What will you help us create?
As a Signal Integrity Engineer, you will be part of the Validation team that is exploring new hardware designs to improve our devices. In this role, you will be responsible for Signal Integrity aspects, compliance, and interoperability of package substrate, PCB, cable solutions and system-level SI for interfaces like PCIe, DDR, and clocks. You will also contribute to package and platform design guideline development.
You will work closely with multi-disciplinary groups including Board Design, System Architects, IP developers, and Design Engineering to verify and deliver complex, high-volume SoCs that enable the development of world-class hardware devices. In this role, you will be:
Responsible for defining the design guidelines for internal and external design teams and delivering reference simulation docs for customers;
Performing modeling of package substrate/PCB channel elements in 3D/2D EM simulation tools;
Working with silicon designers, platform designers, package designers and electrical validation teams to support interconnect and interface performance requirements;
Reviewing and evaluating package and board designs and providing review feedback;
Responsible for providing power delivery solutions across platform, package and SOC level;
Defining worst-case currents and voltage drop scenarios, MIM/decoupling allocation, grid choices and analysis, droop control, SOC ESD compliance, on-die droop detectors, and usage of on-die delivery solutions like VR, LDO, and Power gates.
Basic Qualifications
Bachelor's degree in Electrical Engineering or a related field;
High-speed serial interface analog building blocks, protocols, specifications and test methods;
Familiarity with simulation tools (ADS, HFSS, PowerSI, PowerDC, Hyperlynx) to execute SI-PI simulations;
Experience performing measurements and correlating measurements to simulations;
Experience modeling and simulation of high-speed interface interconnects/channels;
Excellent analytical and problem-solving skills.
Preferred Qualifications
Master’s degree in Electrical or Communications Engineering or a related field;
Experience coding, scripting, and automating in at least one language (e.g., Python, C, C++, Java, Ruby, or PowerShell);
Understanding of Power & signal integrity concepts such as differential impedance, jitter, insertion loss, return loss, termination, etc.;
Experience in Analog IP Characterization (SerDes, PLL, DDR) is desirable;
Good understanding of high-speed analog/digital circuits, VLSI, and semiconductor physics.
Our inclusive culture empowers Amazonians to deliver the best results for our customers.
