Job Description

As a Process, Voltage, and Temperature (PVT) Characterization Engineer, you will be responsible for conducting automated measurement over different conditions for QFN samples on operational mode. The following will be your core responsibilities:

• Collaborate with the internal design team/product management team to meet specifications and measurement requirements effectively.
• Develop and execute SoC PVT characterization test plans in Python to measure the performance of GNSS receiver.
• Collect and organize data to verify RF performance across different operating conditions, such as temperature, voltage, and process corners.
• Utilize Python language including SQL for data management, Jupyter for data visualization and PyQt for creating GUI.
• Debug and troubleshoot issues that arise during testing, including debugging circuits, analyzing data, and proposing solutions in collaboration with design, application and software teams.
• Document test procedures, results, and specifications for datasheet.
• Develop and configure test equipment (hardware/software/automation) in support of performance characterization.

Requirements

Qualinx is looking for a result driven and conscientious Post-Silicon Validation/Characterization Engineer. Someone who thrives in an environment where your proactive and can-do attitude is highly appreciated. The ideal candidate for this role should have:

• BSc or MSc in Electrical Engineering degree.
• In-depth knowledge and experience with RF circuits including digital PLL and oscillators (Crystal & TCXO.
• Experienced in PVT characterizing mixed signal devices with firmware, including automated test management, integration, and lab failure troubleshooting.
• Experienced in data management and data visualization.
• Experience conducting large-scale automation lab testing across multiple products concurrently.
• Experience in working with Lab equipment, including PXIe, Spectrum analyzers, Network analyzers, Digitizing Oscilloscopes, Signal generators, DMMs, and programmable power supplies.
• Familiar with Arm Cortex microcontroller, with knowledge of peripheral interfaces and their integration into embedded systems.
• Proficiency in version control software like GIT.
• Fluency in English, both written and spoken.
• Having knowledge of GNSS and IoT protocols would be considered a bonus point.
• Having the ability to characterize SPI/I2C/UART digital interface would be nice.
• IC design experience is beneficial.
