Sr. Communication Systems Engineer

About the Role

Be part of the team defining the overall communication system and architecture of Amazon Leo’s broadband wireless network. This is a unique opportunity to innovate and define groundbreaking wireless technology with few legacy constraints. The team develops and designs the communication system of Leo and analyzes its overall system-level performance, such as throughput, latency, system availability, and packet loss. This role will lead integration, verification, and testing efforts, particularly focusing on MAC and higher-layer testing, while also developing and testing advanced L1/L2/L3 concepts to enhance the LEO network’s performance and reliability.

Responsibilities

• Work within a project team to take responsibility for Leo’s communication system design, integration, and verification.
• Build a suite of system and network simulation services using Matlab, C++, or Python.
• Develop requirements from system level to HW/SW level and define associated test cases.
• Identify additional HW and SW needed for verification and guide HW/SW development teams.
• Collaborate with implementation teams to simulate system-level performance and provide feedback on improvements.
• Write scripts/code for specific simulation, testing, and verification of RF systems.

Qualifications

• Master’s degree in Computer Science, Computer Engineering, or Electrical Engineering, or equivalent experience in electrical engineering.
• 7+ years of experience in wireless systems design and/or RF design implementation.
• Experience in wireless system design, architecture, integration, and RF system analysis.
• 7+ years of experience developing code in Matlab, C, C++, or Python, with knowledge of industry-standard coding and regression practices.

Preferred Qualifications

• Experience with information theory and network coding.
• Experience with mobile mesh networks.
• Experience in modeling and performance analysis of LEO Satellite Networks.
• Simulation experience with RF standards like 4G/5G, 802.11, DVB-S2/DVB-C, or similar broadband wireless standards.
• Wireless communications system design with emphasis on L1 and L2 layers.
• System and link-level simulation of wireless networks, including capacity, performance, and interference analysis.
• Development of advanced physical layer and MAC layer techniques for wireless networks.
• Understanding of advanced information theory and network coding concepts.
• Excellent analytical, problem-solving, and communication skills.
