Senior Network Software Engineer

We are looking for an experienced Software Engineer with strong technical expertise, solid problem-solving skills, and the ability to work effectively in a collaborative environment.

This role involves working on complex networking systems and low-level software for network devices. While the project is based on SONiC (Software for Open Networking in the Cloud), prior experience with SONiC is considered a strong advantage rather than a strict requirement. Candidates without SONiC experience should be open and willing to learn and work with it.

The ideal candidate has a solid background in system-level development, networking fundamentals, and hands-on experience in both software development and testing.

Key Responsibilities & Expertise:

• Develop and maintain software for networking devices using C/C++ and Python
• Work on system-level components including Linux kernel modules and drivers (FPGA, CPLD)
• Participate in SW/HW bring-up and integration of networking platforms
• Develop automated data path tests using Python/Pytest
• Work with hardware interfaces and buses such as I2C and PCIe
• Use tools such as Jenkins, Scapy, and traffic generators/analyzers for testing and validation
• Collaborate using Git/GitHub within modern development workflows

Nice to have:

• Experience with SONiC Networking OS, including porting and integration on Broadcom-based platforms (Tomahawk, StrataXGS)
• Experience with SAI (Switch Abstraction Interface) for Broadcom ASICs

Networking Knowledge:

• Strong understanding of switching and routing concepts
• Solid experience with L2/L3 protocols
• Hands-on experience with link aggregation and LACP
• Familiarity with dynamic routing protocols such as BGP, OSPF, RIP, and IS-IS

The client may require occasional visits to their office (lab) in Wroclaw, so the candidate should be comfortable with traveling there from time to time.
