• Execute feasibility studies.
• Understand the background of the standards and application scenarios for system implementation.
• Break down the RF and DBB specifications, develop high level models, and run high level verification simulations.
• Review and optimize existing modem algorithms and implementations.
• Verify the functionality and performance of the proposed modem solutions in simulation environments or using fpga test platforms.
• Evaluate the modem solutions in the lab and fine-tune the configuration of the modem towards an optimum system performance and system power consumption balance.
• Support the HW/SW development for evaluation, characterization, and testing.
• Troubleshoot design and architectural issues.
• Document all development / design issues.
• Work closely with multidiscipline team members, and contribute to datasheets, architectural spec’s and development plans.
• Support DFT strategy and implementation.
• Support test development and ramping up production.
• Participate and have a consulting function in reviews of designs, of radio low level driver firmware, as well as of test results from evaluation, characterization, and production testing.
• Function as lead engineer in complex projects.
• Schedule tasks and report progress to project leader; identify project problems.

Guide other engineers.
