What we are looking for:

We are looking for a principal developer for Radio System-on-Chip (SoC) system design within Product Development Unit Radio at Ericsson.

  • You will collaborate with relevant software and hardware architects to explore SoC performance and power trade-offs. Your key responsibilities will include architecting future SoC designs and contribute to SoC roadmap definition.
  • You will be part of our world-class team developing and will be building new tools and methodologies for analyzing and improving SoC designs for radio products in a pre-silicon environment. Simulation, emulation, and hardware profiling will be used to build compelling analysis of new SoC designs. As part of this work, you will participate in the development of best-in-class technology in our RBS products.
  • In addition you are expected to participate to the Ericsson technology edge by filing associated patents.



The principal developer for Radio System-on-Chip system responsibility is to

  • Drive the radio product level functionality and features into Radio SoC requirement and take scoping decisions. The radio requirements include functionalities, features, performance, configurations, capabilities and characteristics.
  • Take technical decisions for structuring and break-downs of radio requirements into each of SoC sub systems as system design solutions.
  • Drive radio SoC architectural and interface design in the SoC development.
  • Drive radio SoC development strategy for various radio product segments in terms of the selection of ASIC implementation or soft DFEs or combinations of them, based on radio SoC requirements.
  • Perform make/buy analysis of SoC chipset solutions.
  • During the pre-silicon process, device tests are needed in a virtual environment with sophisticated simulation, emulation, and formal verification tools. In contrast, post-silicon validation tests occur on actual devices running at-speed in commercial, real-world system boards.
  • Drive pre-silicon performance simulation and post-silicon performance validation for radio product system level evaluation.
  • Develop the system concept of tools to automate test suites and improve the efficiency of functional and performance simulator.


In addition, the position will have the responsibility to

  • Generate IPR’s and drive patent applications in the Radio SoC system design.
  • Guide and coach the SoC system design organization as mentor.


Required qualifications

  • MS degree in Engineering Physics/Mathematics, Electrical Engineering.
  • Minimum 5 years of work-experience in relevant fields of responsibility areas.
  • Experience reading and writing code in Spice, Matlab, C/C++, System C, Verilog and/or VHDL.
  • Experience in SoC architecture performance analysis, tools, and simulators at different abstraction levels.
  • Experience analyzing workloads on SoC development and knowledge of hardware performance monitors or profiling.


Preferred qualifications

  • PhD or Post doc in Engineering Physics/Mathematics/Electronics Engineering.
  • 10-15 years of work-experience in relevant fields of responsibility areas.
  • Experience in SoC architecture performance analysis, tools, and simulators for heterogenous systems
  • Hands-on experience with SoC’s implementing monolithic integration of CPU, GPU, HW accelerators, FPGA fabric and mixed signals
  • Experience designing/implementing or validating RTL for HW accelerators, CPU, GPU, Fabric, Memory
  • Domain knowledge in one or more of these areas: Signal processing for radio front-end, Beamforming, Algorithms for DPD, PIMC, Antenna Calibration
