Senior Principal Developer

About this opportunity

At 5G Cloud RAN Distributed Unit, our main task is to systemize, design, test and deliver RAN Layer 3, Layer 2 and parts of Layer 1 product for Cloud Deployment cementing Ericsson as the front-runner in the market.

We are now looking for a Senior Principal Developer Position Baseband Layer 2 Implementation for Cloud Deployments that will join our excellent team in Kista. This is a key Position to ensure the vital technical leadership for the domain. The challenges to be handled includes (but is not limited to):

• Understand customer expectations on resilience and elastic scaling. Together with the many deployment configurations the implementation will require a dynamic and adaptable thread and process model
• Industry COTS HW offers evolves in a fast pace and the implementation must balance flexibility and portability with performance and utilization to maintain relevancy and technical leadership
• The real-time behavior in the L2 part of the RAN application concerning latency require overcapacity when it comes to inter process communication and thread and memory allocation
• The heterogenous properties of cloud infrastructure with respect to number of cores, clock frequency, memory and instruction set architectures imposes challenges to find balance between computing parallelization and serialization
• The L2 solution will need to run on different HW that may use different NICs and HW accelerators. This must be considered in the choice of architecture.
• The effective run to completion property and vector processing with COTS/Linux gives flexibility and scalability to the system since it is possible to take advantage of system information from users/cells previously scheduled. This allows for new types of algorithms to handle, e.g., interference management, carrier aggregation, and beamforming.
