Job description

Sr. Communication Systems Design Engineer, Wireless Systems

Amazon Kuiper Manufacturing Enterprises LLC, Austin, TX

Job Description:

Amazon Leo is launching a constellation of Low Earth Orbit satellites to provide high-speed broadband connectivity to underserved communities globally. The Systems Engineer will focus on designing, developing, and integrating communication payload and ground terminal systems for this initiative.

Responsibilities:

• Design advanced L1/L2 algorithms and solutions for the Amazon Leo communication system, particularly Multi-User MIMO techniques.


• Develop proof-of-concepts for critical communication payload components using SDR platforms with FPGAs and general-purpose processors.


• Collaborate with ASIC development teams to create efficient L1/L2 HW accelerators for integration into Amazon Leo SoCs.


• Provide specifications and collaborate with implementation teams on embedded L1/L2 HW/SW architectures.


• Work with multi-disciplinary teams to develop advanced solutions for time, frequency, and spatial acquisition/tracking in LEO systems under uncertainties.


• Develop link-level and system-level simulators and provide feedback on performance improvements.


• Create testbeds with digital, IF, and RF components, considering link-budgets and RF/IF line-ups.


• Assist in system integration and debugging from PHY to network layer, interfacing with flight computer and SDN control subsystems.


• Take ownership of the development process from algorithm specification to integration into the Amazon Leo system.


• Support team members and collaborate with RF, ASIC, SW, Comsys, and Testbed teams to advance development and testing activities.

Qualifications:

• PhD or Master's degree with 5+ years of quantitative field research experience.


• 5+ years of professional experience in wireless communications at the system or implementation level.

Skills:

• Deep understanding of Multiple access systems such as OFDMA, TDMA, CDMA.


• Strong grasp of communication theory and digital signal processing, especially in multi-antenna signal processing and interference rejection.


• Expertise in multi-user MIMO processing, including synchronization and channel estimation.


• Knowledge of modem L1/L2 algorithms and architectures.


• Experience in HW/SW co-design for power/area efficient solutions in heterogeneous computing architectures.


• Proficiency in developing link and system level simulators using Matlab.
