Job description

Description

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. Come work at Amazon!

The Role

As Senior RFIC Design Engineer, you will engage with an experienced cross-disciplinary staff to conceive and design innovative product solutions. You will work closely with an internal inter-disciplinary team, and third party suppliers to drive key aspects of product definition, execution and optimization. You must be responsive, flexible and able to succeed within an open collaborative peer environment.

As a member of the RFIC team, you will be responsible for the architectural definition, design, simulation, layout, and extracted simulation for transmit and receive front-ends from data converters to LNAs and PAs. Strong focus will be on creating power and cost optimized solutions for a given system performance.

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

• Collaborate with communications systems, digital design, and chip implementation teams to specify and implement transceivers and RFIC front-end models which will delight future Kuiper customers.
• Lead implementation of area/power-efficient RFIC chips with multiple transceiver chains with integrated PLLs from concept to production.
• Work closely with packaging/HW/EE/FW teams to ensure seamless system integration providing best value for Kuiper customers.
• Collaborate with the digital design team to define analog/digital boundary requirements for circuit calibration, clock generation, and timing.
• Explore architectures for mm-wave and RF circuits like VCOs, mixers, phase shifters, LNAs, PAs, LO distribution, frequency multipliers and dividers, and envelope/power detectors, and make detailed presentations on power/area/performance trade-offs.
• Design and simulate on-chip inductors, baluns, and power combiners in tools such as EMX or HFSS.
• Perform circuit layout, RLC extraction, and run extracted simulation across various corners to make sure designs are robust and can be taken to volume production.
• Specify bench and production test plans for your designs.

Basic Qualifications

• Bachelor's degree in Electrical Engineering or a related field

• 7+ years of experience in mm-Wave/RFIC design, preferably in an advanced node

• Knowledge of current and upcoming RF standards in cellular (4G/5G NR), WiMAX, 802.11ad, microwave backhaul, or similar broadband wireless standards.

Preferred Qualifications

• Master's degree or Ph.D. degree in Electrical Engineering or related field

• RF transceiver architecture / design for beamforming systems (including zero-IF transceivers, low-IF transceivers, polar transmitters, and RF/LO/Baseband phase shifting).

• Experience leading integrated RF transceiver chipsets containing LNAs, PAs, ADCs, DACs, baseband filters, mixers, etc.

• Millimeter-wave circuit design and layout in FinFET, SOI, BiCMOS, and Bulk CMOS technologies.

• Analog circuit design fundamentals, such as Opamps, precision biasing, and LDOs. Electromagnetics of passive devices and device physics of leading edge silicon and III-V devices.

• Mixed-signal design and verification techniques.

• Hands on experience with RF test equipment such as network analyzers, spectrum analyzers, oscilloscopes, and probe-stations.

• Strong written and verbal skills.
