About The Position

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.

As a Satellite RF/Microwave Design Engineer, you will engage with an experienced
cross-disciplinary team to design innovative product solutions. You will work
closely with colleagues throughout Amazon Leo’s inter-disciplinary team in order
to drive key aspects of product definition, execution and optimization. You must
be responsive, flexible and able to succeed within a collaborative and
fast-paced environment.

As a member of the team, you will be responsible for designing microwave/RF
subsystems for use in space. Must be able to work effectively cross-functionally
with multiple disciplines.
In this role you will:
• Decompose system level requirements into realizable hardware requirements.
• Design and develop a solution that meets these requirements.
• Design, develop, and optimize millimeter wave radio hardware for use in space.
• Simulate and optimize RF circuits, perform schematic capture, and oversee PCB
layout.
• Build up test bench for design verification.
• Evaluate and optimize design in the lab to demonstrate solution meets all
requirements.
• Work with RF system, power, software, mechanical thermal, reliability and
compliance teams to ensure solution integrates with overall platform
requirements.

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.

Requirements

• Experience with RF measurement equipment, including: power meters, spectrum analyzers, vector signal generators, network analyzers, oscilloscopes
• Bachelor's degree in Electrical Engineering specializing in RF/Microwave design or equivalent.
• 4+ years of experience in RF / microwave hardware design to component level, such as power amps, LNAs, mixers, and block down-converters, block up-converters, and etc. for commercial or military communication receivers, transmitters and subsystems up to 50 GHz.
• In depth knowledge of radio architectures.
• Experience with RF/ microwave design expertise in Power, Low Noise and Driver Amplifier design for commercial or military communications receivers, transmitters and sub-systems up to 50 GHz.
• Experience with RF simulation software ADS, HFSS, AWR Microwave Office.
• Experience with analog, digital and mixed mode circuit design and layout.
• Excellent math aptitude, written and communication skills.
• Ability to work in a fast-paced environment.

Nice To Haves

• Master's degree or PhD in electrical engineering and 7 years of industry experience in RF/microwave circuits or communication theory
• Experience performing analysis and simulation of communication systems including link budgets
• Thorough understanding of RF passive and active components and circuitry
• Knowledge of digital communication systems, spread spectrum, forward error correcting codes (FEC), single and multi-carrier techniques, modulation types such as PSK, APSK, QAM, OFDM
• Understanding of electromagnetic propagation and antenna systems
• Experience with the design and integration of RF systems consisting of radio transmitters and receivers, LNAs, PAs, couplers, filters, etc.
• Comfortable communicating deeply technical topics to a wide variety of audiences .
• Working knowledge of space environments and the process to space qualify a communication flight unit.
• Familiarity with hybrid microelectronics for space applications and MIL-PRF-38534

Responsibilities

• Will work cross-functionally on collaboration to fluently engage with diverse engineering disciplines, effectively advocate for RF system requirements, and ensure alignment for overall system success.
• Design of high-performance millimeter wave frequency converters, LNAs and SSPAs.
• Develop Microwave and millimeter wave RF hardware requirements.
• Work closely with the production test team to define DVT, Qualification and production test requirements
• Develop, designs, and test of high-power RF/microwave components, subsystems and systems.
• Derive RF HW specifications for the RF system and RF blocks/circuits
• Performs root cause analysis on products, technical problems, processes and documentation.
• Assess feasibility of various designs in support of architectural definition
• Participate in subsystem design and prototyping, schematic capture, prototype bring-up and debugging, hardware bug tracking, functional verification, and signal characterization
• Evaluate and characterize new technology, prototypes and RF components
• Evaluate systems and directs design modifications.
• Troubleshoots and repairs circuits and fixtures.
