Full-time.\nAbout the role\nWe 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.\nThis is a role for a strong embedded Linux developer who wants to become a switching specialist.\nPrevious switch silicon experience is not required. What we need is depth in embedded C on\nLinux, a real understanding of networking, and the appetite to learn quickly - the specialist\nknowledge is what the senior developers on the team will teach you.\nWhat you will do\nImplement and maintain switching features on our Linux-based NOS - VLANs, link aggregation, spanning tree, QoS, access lists, multicast snooping, DHCP relay.\nWrite drivers and platform code against switch ASIC and PHY SDKs.\nBuild and debug images for our switch platforms, and diagnose failures on real hardware in the lab.\nWrite test cases and automation that prove a feature works and keep it working.\nInvestigate and resolve defects reported from customer networks.\nDocument what you build, including build and debug procedures.\nWhat we offer\nStructured 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.\nRequirements\n3-6 years of embedded software development, primarily in C.\nSolid embedded Linux experience: cross-compilation, kernel modules or drivers, user-space system software, and a build system such as Yocto, Buildroot or equivalent.\nNetworking knowledge - the OSI model in practice, Ethernet framing, VLANs, switching versus routing, TCP/IP. Hands-on with Wireshark or equivalent.\nAbility to work from a datasheet and a register map, and to debug on hardware with a serial console and JTAG.\nVersion control (Git; SVN useful) and a disciplined approach to code review.\nWorking English, at least in reading and writing.\nBachelor's degree in Computer Science, Electronics, Telecommunications or equivalent experience.\nNice to have\nExposure to switch or router software, or to an ASIC/NPU SDK.\nTelecom or networking equipment background - OLT, DSLAM, CPE, base station, enterprise switching.\nScripting for test automation (Python).\nL2 protocol implementation experience of any kind.\nFamiliarity with SNMP, CLI frameworks, or NETCONF/YANG.","description_format":"text","description_chars":2505,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Vietnam","iso":"VN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Telecommunications","Broadband"],"lifecycle":[{"event":"open","at":"2026-10-09T18:18:06Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:3","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/zhone-embedded-software-developer-mid-level-network-switch","json_url":"https://alion.io/job/zhone-embedded-software-developer-mid-level-network-switch.json","meta":{"generated_at":"2026-10-11T21:32:08Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":10493,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2152358},"rest":"https://alion.io/mcp/rest/get_company?id=2152358"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzhone-embedded-software-developer-mid-level-network-switch"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fzhone-embedded-software-developer-mid-level-network-switch"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fzhone-embedded-software-developer-mid-level-network-switch"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/zhone-embedded-software-developer-mid-level-network-switch\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzhone-embedded-software-developer-mid-level-network-switch"}]}
