Nokia

Nokia is a Finnish telecommunications equipment company founded in 1865 as a paper mill, which became the world's largest mobile phone maker in the 1990s before selling that business to Microsoft in 2014. It now supplies network infrastructure to operators and enterprises, covering radio access equipment for mobile networks, optical and IP routing for transport networks, fixed broadband access, and a technologies division that licenses its cellular patent portfolio. Headquartered in Espoo and listed in Helsinki and New York, it runs Nokia Bell Labs as its research arm and has been expanding into data centre networking as operator spending has slowed.

We are seeking a highly skilled and experienced Engineer with a strong background in telecommunications networking. The ideal candidate will possess deep expertise in data plane software development for PHY, PCS, MAC layers, transceivers, and IEEE 802.3 standards, coupled with robust C/C++ programming skills. This role is crucial for developing and optimizing high-performance carrier-grade hardware products.

NIFN2026

  • Develop and optimize data plane software for high-performance, carrier-grade networking hardware, focusing on PHY, PCS, MAC, and transceiver layers that comply with IEEE 802.3 standards.

  • Design, implement, and maintain low-level drivers and HALs for ASICs and optical transceivers, working closely with Broadcom, Marvell, and in-house chipsets.

  • Analyze and troubleshoot packet forwarding paths to diagnose complex Layer 1 and Layer 2 networking issues, ensuring optimal throughput and reliability.

  • Collaborate with hardware and system teams to derive software requirements from schematics, datasheets, and hardware documentation, validating designs through lab testing.

  • Debug, profile, and optimize embedded software running on RTOS environments (e.g., VxWorks), ensuring performance, stability, and carrier-grade quality.

You Have:

  • Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field. 4+ years of relevant experience in embedded or networking software development.

  • Proficiency in C, C++, and Assembly programming.

  • Experience with RTOS concepts and VxWorks development.

  • Experience working with Broadcom, Marvell, or custom ASIC chipsets. Strong background in HAL development for ASICs and transceivers.

  • Familiarity with SFF, MSA, and CMIS 5.2 specifications for optical modules.

  • Solid understanding of SerDes fundamentals (FFE, DFE, insertion loss, signal integrity).

  • Good experience with Layer 1 and Layer 2 networking protocols.

  • Deep knowledge of IEEE 802.3 Ethernet standards (PHY, PCS, MAC).

  • Hands-on experience with packet forwarding analysis and troubleshooting.

It would be nice if you also have:

  • Direct hands-on experience with Broadcom and/or Marvell SDKs and chipsets.

  • Proficiency with protocol analyzers and debugging tools (e.g., Wireshark).

  • Experience with hardware simulation or emulation environments.

  • Familiarity with QEMU, automated test frameworks, and lab validation setups.

  • Exposure to large-scale system integration and field issue debugging in telecom environments.
