Open Networking Support Specialist

PLVision seeks an Open Networking Support Specialist to work directly with enterprise, hyperscaler, telco, and data center customers running SONiC and SONiC Lite-based network operating systems.

The role lives at the intersection of networking, Linux systems, and product engineering. You will work on real production networking issues, collaborate closely with L3 and engineering teams, and help improve product quality and stability.

This is an L2+ advanced networking engineer position (not a call center) – technically demanding and focused on root cause analysis, structured troubleshooting, and continuous product improvement.

At PLVision, we lead meaningful technical projects that significantly impact the open networking industry, helping you build a brighter future. With over 18 years of expertise and a highly skilled, recognized, and supportive team, we are deeply committed to engineering excellence. We provide a rewarding environment where you can thrive and transform your ideas into impactful software solutions and products.
