About the Job

Requirements

A Master's degree or PhD in Electronic Engineering, Microelectronics, Telecommunications Engineering, or a related technical field.
Strong hands-on laboratory experience working directly with electronic or radio-frequency 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 or high-frequency measurement equipment, such as oscilloscopes, network analyzers, signal generators, and related radio-frequency test equipment.
A 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.
A basic understanding of digital signal processing and signal analysis.
A basic understanding of firmware/software interfaces used to control and test hardware.
Fluent written and spoken English.
German language skills may be expected depending on team requirements.
Strong analytical and problem-solving skills, and the ability to work effectively with international engineering teams.

Responsibilities

Perform hands-on laboratory testing and characterization of high-speed ADCs and DACs.
Set up, operate, and optimize high-frequency/radio-frequency test and measurement equipment, including oscilloscopes, network analyzers, signal generators, and related laboratory equipment.
Execute measurements on ADCs and DACs 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 laboratory.
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.

Desired Qualifications

Experience with very high-frequency/radio-frequency measurements, particularly in millimeter-wave or above-100-GHz environments.
Experience with ADCs/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.

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.

About the Company

Nokia

Makes network gear for carriers and data centers

Nokia makes the equipment and software that mobile carriers, cloud companies, and businesses use to run networks, from cell-tower radios to fiber links between AI data centers. From 1998 to 2011 it was the world's largest mobile phone maker; it sold that business to Microsoft in 2014, and HMD Global, a separate company, makes Nokia-branded phones under license. Its network unit sells optical systems that send data over fiber, internet routers, and broadband gear, and its mobile unit sells radios and the core software that runs 5G networks. Nokia earns money from equipment and service contracts and from licensing its patents to phone makers and carmakers. It was founded in 1865 as a wood pulp mill and is based in Espoo, Finland.
