In an increasingly connected world, the pandemic has highlighted just how essential telecom networks are to keeping society running. The Network Infrastructure group is at the heart of a revolution to connectivity, pushing the boundaries to deliver more and faster network capacity to people worldwide through our ambition, innovation, and technical expertise

Join Optical Networks division, where innovation meets scale in the AI-driven data center era. With the recent acquisition of Infinera, we’ve united two industry leaders to create an optical networking powerhouse—combining cutting-edge technology with proven leadership to redefine the future of connectivity.

Nokia's Optical Networks division pioneers high-performance optical networking solutions, essential for powering the AI super cycle and the evolving cloud-networked economy. As High-Speed Converters Test and Validation Engineer, you will play a pivotal role in this mission, directly contributing to the development of coherent Digital Signal Processors (DSPs) and Transmission Modules – the intelligent core of our optical transmission products.

Our ASIC/SoC team manages the complete lifecycle of ASICs for optical modules, from architectural definition and specification to implementation and testing. Our primary objective is to push the boundaries of optical reach and transmission bandwidth, while simultaneously achieving significant reductions in power consumption and physical footprint through state-of-the-art chip technologies.

• Master’s degree or PhD in Electronic Engineering, Microelectronics, Telecommunication Engineering or similar.

• Deep knowledge of ADC and DAC technology and designs; strong practical experience with associated measurement methodologies.

• Proficiency regarding high-frequency measurement equipment (Sampling and Real-Time Scopes, Network Analyzers) in frequency ranges above 100 GHz

• Good knowledge about lab setups in general, test equipment control, DUT control using scripts and FW/SW modules, esp. for ADC/DACs, standalone or embedded in DSP ASICs

• Proven experience in writing Python code for lab automation is a must. Experience with Matlab is an additional asset.

• Basic understanding of (digital) signal processing and signal analysis.

• Basic understanding of firmware development, software structures and methods (C/C++, development of drivers and APIs for the design blocks)

• Good communication skills, fluent written and spoken English (required) and German (expected), with a strong interest to collaborate with international partners.

Nice to have

• Knowledge of coherent optical transmission systems and their components, transmission theory and algorithms, modulation formats and respective implementations

• Knowledge of device packaging technologies, package characterization and de-embedding

• Knowledge of LINUX-based systems IT infrastructure management

• Inter-disciplinary and inter-cultural collaboration experience

Nokia is a global leader in connectivity for the AI era. With expertise across fixed, mobile and transport networks, powered by the innovation of Nokia Bell Labs, we’re advancing connectivity to secure a brighter world.
