Role Overview:
We are seeking a highly skilled Firmware Wireless Communications Engineer to join the existing team, the engineer should have 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.). This role requires a deep understanding of wireless communication protocols, PHY layer development, and hands-on experience with RF hardware.
Key Responsibilities:
- PHY Layer Integration: Configure and optimize RF front-end chipsets (e.g., Analog Devices transceivers: AD936x) for various cellular technologies, frequencies and bandwidths, to be able to configure and control other on-board capabilities, such as, PLLs, clocks, I2C peripherals, etc.
- Testing and Validation: Conduct lab testing and validation of SDR-based PHY layer solutions, Utilize test equipment such as spectrum analyzers, signal generators, and vector signal analyzers (VSAs) for PHY and RF performance tuning, Perform over-the-air (OTA) testing and analysis.
- System Optimization: Analyze system-level performance, including signal quality, throughput, and latency. Optimize RF front-end configuration for different environmental and operational conditions.
- Documentation: Provide comprehensive technical documentation, including design specifications, test reports, and user guides. Maintain system configuration and troubleshooting records.
Qualifications & Experience:
- Education: Bachelor’s degree or higher (preferably) in Electrical Engineering, Telecommunications, or a related field.
- Experience: 5+ 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.
- Technical Skills: Proficient in working with SDR platforms (e.g., USRP, LimeSDR, Xilinx Zynq-based boards). Strong understanding of RF front-end devices like Analog Devices AD936x, etc. Expertise in signal processing concepts (OFDM, MIMO, beamforming, etc.). Strong programming skills in C/C++, preferable Python, or MATLAB for system implementation and testing. Experience with RF test and measurement tools.
- Additional Skills: 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.
