Amazon.com Services LLC - Redmond, WA

Employment Type : Full-Time

  • Bachelor’s degree in Electrical Engineering or related discipline, or equivalent experience.
  • Wireless Communications System design and development experience.
  • 5+ year’s professional experience working in Layer-2 Protocol, Media Access Control (MAC) layer.
  • 5+ years of experience developing code in NS3, OPNET, Matlab, C, C++, or Python.
Project Kuiper 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 Wireless Systems Engineer – Layer 2/ MAC layer, you will work with a wide variety of functional groups and will be deeply involved in system requirements and modeling traffic flow scenarios to validate the design.

In this role you will:
  • Be part of the team defining the system design, architecture of Project Kuiper’s broadband wireless Layer-2 MAC (Data path and control path) system design and architecture from customer end points via Low Earth Orbit Satellites
  • Create the systems specification/documentation for technical-focused implementation such as Layer-2 standards published for 3GPP, WiMAX, DOCSIS, WiFi etc
  • Work as a part of the team with customer & business requirements to define the throughput / availability of network resources, assignment of resources to each customer area and develop algorithms for optimal radio resource allocation and coordination mechanisms.
  • Work as a part of the team in building a suite of system and network simulation environment in NS3/ Matlab / C++ / Python.
  • Work as a part of the team drives trade-off analysis to benefit customer experience and optimization of resources (costs, power, latency, spectrum efficiency, etc.) and develop packet queuing and scheduling algorithms.
  • Drive various system level optimizations.
  • Work as a part of the team to work closely with hardware and software implementation teams to evaluate and simulate expected system level performance and provide quick feedback on potential improvements.
  • Work as a part of the team to work with the Test teams to seamlessly test and validation of System Design and performance evaluation.
  • Work as a part of the team to work with the Physical layer and Network layer teams to seamlessly integrate the link-layer within the Network stack.
