An RF Communications Design Engineer participates in the full product development lifecycle, from inception and supports new and current customers with the evolution of wireless standards and their measurements.

Key responsibilities include:

• Primary development in C++ under Linux environment.
• Designing and developing digital signal processing algorithms for RF waveform design and analysis.
• Developing DSP algorithms for measurement of wireless communication standards such as Wi-Fi (802.11), cellular (LTE, 5GNR), and IoT standards (NB-IoT, LTE-M, Zigbee, and Bluetooth).
• Deploying DSP algorithms in Cohu’s Modulation library for use in our proprietary operation environment.
• Conducting performance analysis and optimization of DSP algorithms implemented in FPGAs and other DSP ICs.
• Implementing and maintaining RF waveform software tools for waveform design and measurement.
• Providing technical guidance for Applications Engineers and Software Engineers to define and implement diagnostic C++ programs for the generation and analysis of Wireless Communication Standards.
• Root cause analysis, debugging, and problem resolution for customers using our Wireless Communication Libraries.
• Remaining abreast of the latest advancements in digital signal processing, wireless communication standards, and related technologies.
• Collaborating within the software organization to identify and address process issues.
• Mentoring junior software engineers working in the same discipline.

Education and Experience/Skills Required:

• Bachelor's Degree in Computer Engineering, Electrical Engineering, or a related field with software experience-required. Master's or Doctorate Degree- preferred.
• 5-15 years of experience in the field or in a related area.
• Strong proficiency in C++ and Object-Oriented Programming.
• Solid understanding of digital signal processing fundamentals, algorithms, and implementations.
• Strong analytical and problem-solving skills with the ability to debug and troubleshoot complex RF communication systems.
• Familiarity with wireless communication protocols (e.g., 5G NR, LTE, Zigbee, Bluetooth) is required.
• Experience with developing calibration algorithms and real time processing strategies for both source and measurement solutions (Equalization, Predistortion, IQ Alignment).
• Prior experience in RF waveform design, optimization, and measurements for communication standards is highly desirable.
• Working knowledge of Analog, Digital, and RF circuit design is desirable.
• Experience implementing Signal Processing Algorithms in FPGAs is desirable.
• Experience or familiarity with radio frequency devices and/or systems is desirable.
• Exposure to LINUX workstations and associated software applications preferred.
• Effective verbal and written communication skills.
• Ability to work collaboratively with other functional teams.
