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.
• Integrate the link-layer with simulation infrastructure and work closely with implementation teams to determine external technology suppliers.

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.

• Experience with industry standard coding and regression practices for modeling and validating MAC protocols.
• Experience in wireless standards like 3GPP 5G/LTE/4G/3G, DOCSIS, WiFi/ 802.11, Wimax, DVB-S2 / DVB-C, OR similar broadband wireless standards focusing on Layer-2/MAC layer and experience in writing Layer-2 protocol specifications for either wireline or wireless broadband communication systems.
• Wireless communication experience with the emphasis on L2 data plane and control plane protocols (i.e. MAC, RLC, PDCP, SDAP, RRC ).
• Capacity, performance, latency and overhead analysis of wireless networks.
• Knowledge of IP, UDP, TCP, HTTP protocols, 3GPP NTN knowledge is a plus.
• Broad spectrum of knowledge to be able to understand end-to-end network system architecture from wireless physical layer all the way up to application end-point.
• Excellent analytical, problem solving, and communication skills.
