GRS Recruitment is excited to announce an excellent opportunity for a Wireless Communications Engineer to join our esteemed client in Nicosia. This role is ideal for professionals with a solid background in Telecommunications who are looking to advance their career in a dynamic environment. We are seeking a highly skilled Wireless Communications Engineer with expertise in cellular communication systems, Software-Defined Radios (SDR), and RF front-end integration. The ideal candidate will be responsible for integrating physical layer (PHY) stacks on SDR platforms and configuring RF chipsets, such as those from Analog Devices (AD936x, etc.). If you feel you have the necessary skills, please apply today for this Nicosia based role.
MAIN DUTIES AND RESPONSIBILTIES
- Integrate and optimize the physical layer stack (LTE/5G NR) on SDR boards.
- Implement algorithms for signal processing, including synchronization, channel estimation, and demodulation.
- Configure and optimize RF front-end chipsets (e.g., Analog Devices transceivers: AD9361) for various cellular frequencies and bandwidths.
- Work with tuning parameters like LO frequency, gain control, and filters to meet system performance requirements.
- Develop and integrate drivers and firmware for SDR boards to communicate with RF front-end chipsets.
- Collaborate with software teams to optimize PHY performance.
- Conduct lab testing and validation of SDR-based PHY layer solutions.
- Utilize test equipment such as spectrum analyzers, signal generators, and vector network analyzers (VNAs) for RF performance tuning.
- Perform over-the-air (OTA) testing and analysis.Analyze system-level performance, including signal quality, throughput, and latency.
- Optimize RF front-end configuration for different environmental and operational conditions.
- Provide comprehensive technical documentation, including design specifications, test reports, and user guides.
- Maintain system configuration and troubleshooting records.
CANDIDATE PROFILE
- Bachelor’s degree or higher in Electrical Engineering, Telecommunications, or a related field.
- 3+ years of hands-on experience in cellular communications, SDR development, and RF front-end configuration.
- Experience integrating PHY layers for LTE, 5G NR, or similar wireless standards.
- Proficient in working with SDR platforms (e.g., USRP, LimeSDR, Xilinx Zynq-based boards).
- Strong understanding of RF front-end devices like Analog Devices AD9361, etc.
- Expertise in signal processing concepts (OFDM, MIMO, beamforming, etc.).
- Programming skills in C/C++, Python, or MATLAB for system implementation and testing.
- Experience with RF test and measurement tools.
- Knowledge of cellular communication protocols: LTE, 5G NR, and GSM.
- Familiarity with OpenAirInterface or similar open-source cellular frameworks is a plus.
- Strong analytical and problem-solving abilities.
- Excellent communication and teamwork skills.
- Experience with FPGA-based PHY implementations.
- Knowledge of RF design principles, impedance matching, and antenna systems.
- Familiarity with embedded systems and real-time software environments.
