Description
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.

Responsibilities
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.

Qualifications
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).
- Valuable experience with Layer 1 and Layer 2 networking protocols.
- Deep knowledge of IEEE 802.3 Ether
