Senior SoC/FPGA Engineer

Job Description

The NOKIA Optics Subsystems group develops the front-ends for coherent optical long-distance transmission modules to interconnect network nodes and data centers. We are expanding and looking for highly motivated and experienced engineers to join us to develop the next generations of transmission systems.

Within Optics Subsystems, the SoC (System-on-Chip) team members architect, specify, design and test the ASICs for the optical modules. Our main goal is to extend the optical reach and transmission bandwidth and at the same time reduce the power and floorspace needs by using the latest chip technologies.

How You Will Contribute And What You Will Learn

• Contribute to the end-to-end architecture and implementation of high-performance DSP/FEC for coherent optical ASICs, turning advanced theory into silicon-proven capability.
• Develop, simulate, and validate new DSP and FEC algorithms (floating‑point and fixed‑point) to enhance performance, expand functionality, and reduce power consumption.
• Assess end‑to‑end link performance through system‑level simulations and practical measurements in optical transport environments.
• Partner with ASIC design teams to integrate DSP algorithms into coherent modem architectures.
• Prototype, test, and tune algorithms on hardware; reconcile lab results with pre‑silicon simulations.
• Analyze transceiver module performance and refine system models and simulation environments to align with requirements.
• Monitor algorithm performance continuously and share insights with cross‑functional teams.
• Coordinate with the firmware teams on feature implementation and software/hardware co‑design.
