Job Description
 
The Radio System-on-Chip System Design unit has the systemization responsibility in terms of radio requirement management for radio ASICs (Application Specific Integrated Circuits), FPGA (Field-Programmable Gate Array). The radio System-on-Chip (SoC) is the heart of the Ericsson radio units, which are part of Ericsson’s 2G, 3G, 4G and 5G base stations. The focus area of the organization unit is the systemization of radio features and radio functionalities which are to be implemented on System-on-Chips.
The radio functionalities will be implemented into the architectural functions, the interfaces on control plane and user plane of the radio signal in downlink and uplink, as well as control functions in CPU (Central Processor Unit) sub systems and other sub systems such as DSP (Digital Signal Processing), memory, ROM (Read-Only-Memory) Boot and Security.

 

Responsibilities and tasks

·        Drive systemization of radio unit’s functionalities, features, interfaces, configuration capabilities and subsystems. which are to be implemented in ASIC/FPGAs function blocks

·        Participate or drive technical analysis studies and pre-development in the SoC systemization areas

·        Creating for radio ASICs and FPGAs design and implementation the necessary requirements into requirement specifications

·        Support to design team during development, verification, and validation of the design.

·        Continuously improve and optimize ways of working

 

Qualification Requirements

 

·        Master of Science, Ph.D., Post Doc or similar degrees in Electrical Engineering, Engineering Physics or Computer Science

·        Proficiency within the field of signal processing, telecommunication systems and radio technology

·        Systemization knowledge of combined hardware, firmware, middleware and software domains

·        Radio systemization experience in requirement setting for GSM, WCDMA, LTE and NR

·        Experiences on systemization of radio DPD (Digital Pre-Distortion), PIMC (Passive Inter-Modulation Cancellation), DAC/ADC (Digital-Analog Converter/Analog-Digital Converter) and ORAN (Open Radio Access Network) are preferred

·        Knowledge in embedded systems, system-on-chip, ASIC, FPGA

·        Advanced proficiency level of English language is mandatory, language knowledge in Swedish or Chinese is beneficial.
