High-Speed Converters Test and Validation Engineer

Join Nokia’s Optical Networks division and contribute to the development and validation of advanced high-speed converter technology used in next-generation optical transmission systems.

We are looking for a High-Speed ADC/DAC Test Engineer with strong hands-on laboratory experience. This is a practical, lab-focused engineering position for someone who is comfortable working directly with high-frequency test and measurement equipment and has experience characterizing Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs).

The successful candidate will spend a significant part of their time working in the lab, setting up and executing measurements, analyzing results, troubleshooting issues, and improving test methodologies for high-speed converter technologies.

As a High-Speed ADC/DAC Test Engineer, you will

• Perform hands-on laboratory testing and characterization of high-speed ADCs and DACs.
• Set up, operate, and optimize high-frequency/RF test and measurement equipment, including oscilloscopes, network analyzers, signal generators and related laboratory equipment.
• Execute measurements on ADCs and DACs, both as standalone devices and when integrated into DSP/ASIC solutions.
• Develop, improve and maintain automated test setups and measurement scripts, primarily using Python.
• Analyze measurement results and identify performance limitations or unexpected behavior.
• Troubleshoot hardware, test setup and measurement issues in the lab.
• Work closely with ADC/DAC designers, ASIC/DSP teams and other hardware development teams to explain test results and support debugging.
• Improve test methodologies to increase measurement accuracy, repeatability and efficiency.
• Support the transition of test methodologies from development into manufacturing and volume testing.
• Collaborate with engineering teams across international Nokia locations.
• We are looking for candidates with:
• Master’s degree or PhD in Electronic Engineering, Microelectronics, Telecommunications Engineering, or a related technical field.
• Strong hands-on laboratory experience. Candidates should have spent significant time working directly with electronic/RF test setups and equipment.
• Practical experience testing and characterizing Analog-to-Digital Converters (ADCs) and/or Digital-to-Analog Converters (DACs).
• Experience with high-speed/high-frequency measurement equipment, such as oscilloscopes, network analyzers, signal generators and related RF test equipment.
• Good understanding of ADC/DAC performance and measurement methodologies.
• Experience building, configuring and troubleshooting complex laboratory test setups.
• Python programming experience for test automation and laboratory equipment control.
• Basic understanding of digital signal processing and signal analysis.
• Basic understanding of firmware/software interfaces used to control and test hardware.
• Fluent written and spoken English. German language skills are an advantage/expected depending on the requirements of the team.
• Strong analytical and problem-solving skills and the ability to work effectively with international engineering teams.

Nice to have

• Experience with very high-frequency/RF measurements, particularly in mmWave or >100 GHz environments.
• Experience with ADC/DACs integrated into DSPs or ASICs.
• MATLAB experience.
• Knowledge of coherent optical transmission systems.
• Experience with device/package characterization and de-embedding.
• Linux experience.
• Previous experience working in multidisciplinary hardware development teams.
