What You'll Be Responsible For
Lead
RF / microwave / mixed-signal hardware design
across the full lifecycle Drive
feasibility studies, simulations, and prototyping Own
schematic design, PCB layout collaboration, and production sign-off Perform
board bring-up, RF tuning, and root-cause debugging Define and execute
system validation strategies (EVT / DVT / PVT) Execute
RF calibration and performance optimization
at both module and system levels Troubleshoot
high-frequency performance bottlenecks in dense RF systems Support
NPI, manufacturing scale-up, and production validation Mentor engineers and provide
technical leadership
What Makes You a Strong Fit
Bachelor/Master's degree in Electronics and Communication engineering or a related field 5+ years of experience in
RF / microwave hardware design and productization Strong hands-on expertise in
