If you want to make a big impact with a small team and are looking to expand your skill set, this is the place.

As a Wireless System Engineer, you will be working in a design engineering team in modeling 5G Tx/Rx PHY Tx/Rx blocks.

Key Responsibility:

  • Evaluate various algorithms and architectures by implementing Matlab models and analyze performance trade-offs
  • Collaborate with design engineers on microarchitecture and generate test vectors for design verification
  • Work with design engineers to come up with comprehensive test plans and debug issues.
  • Design and develop signal processing/communication algorithms for wireless MIMO system in 5G ORAN
  • Modeling of baseband/passband DSP blocks in floating and fixed point formats for optimum performance/area trade-offs
  • Integrate IP models at SOC level and conduct C/C++ and Matlab simulations to study system performance
  • Generate reference model and test vectors in cycle true & bit accurate format for digital IP and SOC verification
  • Work closely with the digital designer with implementation that meets system requirements
  • Work with digital design engineer to debug issues found in verification
  • Define IP functional requirements and specifications at system level
  • Participate in post-silicon bring-up, performance characterization and optimization
  • Field testing and verify product performance using lab instruments
