Embedded Software Developer (Mid-Level) - Network Switch

Embedded Software Developer (Mid-Level) - Network Switch

Location: Hanoi, Vietnam. Full-time.

About the role

We are building a new switching software team in Hanoi to own the network operating system on Zhone's carrier Ethernet switches. These are products running in live operator networks in Europe.

This is a role for a strong embedded Linux developer who wants to become a switching specialist.

Previous switch silicon experience is not required. What we need is depth in embedded C on

Linux, a real understanding of networking, and the appetite to learn quickly — the specialist

knowledge is what the senior developers on the team will teach you.

What you will do

• Implement and maintain switching features on our Linux-based NOS — VLANs, link aggregation, spanning tree, QoS, access lists, multicast snooping, DHCP relay.
• Write drivers and platform code against switch ASIC and PHY SDKs.
• Build and debug images for our switch platforms, and diagnose failures on real hardware in the lab.
• Write test cases and automation that prove a feature works and keep it working.
• Investigate and resolve defects reported from customer networks.
• Document what you build, including build and debug procedures.

What we offer

Structured mentorship from senior switching developers and a deliberate path from general embedded work into a specialism that is scarce in the market. You will work on hardware you can hold, in networks carrying real subscriber traffic.
