We're evolving how we integrate with switches - moving toward more modern network management protocols and a wider range of vendors. You'll own that integration layer end-to-end - backend services and the networking know-how behind them.\nResponsibilities\nDesign and build the software that talks directly to enterprise network switches: real devices, real production networks, real impact.\nPush the boundaries of how we manage devices at scale: new protocols, new vendors, better abstractions.\nBuild the cloud backend that turns raw device data into something powerful (Go/C#, gRPC, PostgreSQL).\nSolve hard, unglamorous distributed-systems problems: concurrency, reliability, scale - with code that ships to production and protects real infrastructure\nRequirements\n3-5 years as a backend engineer, proficiency in at least one of Go/C#/Java/C++.\nNetworking knowledge: L2/L3, VLANs, routing, TCP/IP, ACLs.\nHands-on experience automating network devices - SSH/CLI, NETCONF, RESTCONF, SNMP, gNMI, Netmiko/NAPALM, or similar.\nComfort with concurrent code that has to survive flaky real-world network conditions\nNice to Have\nMulti-vendor network experience (Cisco, Aruba, and others).\nCloud experience (GCP/AWS/Azure) and microservices/gRPC.\nExperience with flow-based telemetry protocols (IPFIX, NetFlow, sFlow).\nTech Stack\nGo, C#, PostgreSQL, gRPC, GCP, microservices, and standards-based network management protocols.","description_format":"text","description_chars":1541,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Biotechnology","Cybersecurity"],"lifecycle":[{"event":"open","at":"2026-10-14T05:26:15Z"}],"visa":[],"liveness":{"score":85,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.896,"p_room":0.945,"age_days":7,"expected_fill_days":22,"reasons":["conf:1","velocity","win:mid"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/zero-networks-backend-engineer-ot-security-team","json_url":"https://alion.io/job/zero-networks-backend-engineer-ot-security-team.json","meta":{"generated_at":"2026-10-21T15:28:40Z","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":22008,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":1896410},"rest":"https://alion.io/mcp/rest/get_company?id=1896410"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzero-networks-backend-engineer-ot-security-team"},{"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%2Fzero-networks-backend-engineer-ot-security-team"},{"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%2Fzero-networks-backend-engineer-ot-security-team"},{"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/zero-networks-backend-engineer-ot-security-team\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzero-networks-backend-engineer-ot-security-team"}]}
