The ideal candidate will design, deploy, operationalize, and maintain high-performance Software-Defined Network (SDN) architectures, bridging deep data center networking expertise with modern cloud-native telemetry, microservices, OpenStack environments, and Kubernetes-native application development.\n\nRoles and Responsibilities : \n\nSDN & Virtual Switching : \n\n- Architect, maintain, and optimize Open Virtual Switch (OVS) and Open Virtual Network (OVN) dataplanes. Manage OpenFlow pipelines and SDN controllers for automated flow control.\n\nCloud Infrastructure & Kubernetes : \n\n- Deploy and operationalize OpenStack networking services (Neutron, Metadata Service) using OpenStack Ansible. Contribute to the development of cloud-native networking products, microservices, and controllers for our Kubernetes product ecosystem.\n\nOverlay & Underlay Networking : \n\n- Design, optimize, and troubleshoot overlay tunnels (VxLAN, GENEVE) and virtual networks (VLAN 802.1Q) running over high-throughput physical fabrics (L3 CLOS, LACP, MCT/vLAG).\n\nL2/L3 Routing & Switching : \n\n- Implement and manage dynamic routing protocols (BGP, EVPN, OSPF) for WAN/DC interconnects, ECMP load balancing, and VRRP gateway redundancy.\n\nNetwork Security : \n\n- Secure network traffic across untrusted boundaries using IPsec VPNs (IKEv2, ESP). Configure stateful firewalls, connection tracking (Conntrack), and NAT rules using IPTables/Netfilter and NFTables.\n\nAutomation, Telemetry & Lifecycle Management : \n\n- Build, test, and validate network topologies locally using Vagrant and hypervisors (KVM/QEMU) prior to production rollouts. Develop resources to handle platform upgrades, real-time streaming telemetry architectures (gRPC, ProtoBuf, Kafka), and network lifecycle management.\n\nTechnical Requirements & Skill Stack : \n\nCloud & Virtualization Platforms : \n\n- OpenStack (Neutron, Nova, Metadata Service), OpenStack Ansible, KVM/QEMU, DevStack\n\nSoftware-Defined Networking (SDN) : \n\n- Open vSwitch (OVS), Open Virtual Network (OVN), OpenFlow, SDN Controllers\n\nOverlay & Encapsulation : \n\n- VxLAN, GENEVE, VLAN (802.1Q)\n\nL2/L3 Protocols & Data Center : \n\n- BGP, EVPN, OSPF, ECMP, VRRP, IPv4/IPv6, ARP/NDP, Ethernet (802.3), STP/RSTP, L3 CLOS, LACP, MCT/vLAG\n\nCloud-Native & Telemetry : \n\n- Kubernetes, Docker, Kubernetes Controllers, Operator SDK, CRDs, gRPC, Protocol Buffers, Kafka, Numaflow\n\nSecurity & Packet Inspection : \n\n- IPsec (IKEv2, ESP), IPTables/Netfilter, NFTables, Conntrack\n\nDevOps, Automation & Languages : \n\n- Golang (Go), Python, C, Vagrant, Ansible, Linux CLI, Bash, CI/CD (Jenkins, Git), OpenAPI / REST APIs\n\nPreferred Qualifications : \n\n- Bachelor's degree in Computer Science or a related field with 8 - 15 years of software development and infrastructure experience across cloud engineering, telecommunications, or large-scale data center environments.\n\n- Deep expertise in Linux networking concepts, packet path traversal, and kernel-level networking subsystems.\n\n- Proven track record with production OpenStack deployments using OVN/OVS as the default networking backend.\n\n- Strong proficiency in Golang, Python, or C with hands-on experience in white-box switch network management applications.\n\nBenefits and Perks : \n\n- Competitive Compensation and Equity\n\n- Medical Healthcare for you and your family\n\n- Hybrid Work Model\n\n- Wellness Benefits\n\n- Professional Development/Global certifications\n\n- Reward and Recognition Programs\n\n- Team Building Activities\nSkills\nNetwork Infrastructure, Network Component, Network Protocols, SDN, Kubernetes, Routing & Switching, Network Security, IT Automation, Virtualization, Datacenter, Cloud Infrastructure","description_format":"text","description_chars":3778,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Hybrid work","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-12T12:29:15Z"}],"visa":[],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":0.85,"p_active":0.809,"p_room":0.75,"age_days":20,"expected_fill_days":28,"reasons":["seen:20","win:late"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/subir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer","json_url":"https://alion.io/job/subir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer.json","meta":{"generated_at":"2026-11-02T12:07:02Z","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":16622,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":4424175},"rest":"https://alion.io/mcp/rest/get_company?id=4424175"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsubir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer"},{"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%2Fsubir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer"},{"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%2Fsubir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer"},{"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/subir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsubir-sinha-hr-corporate-advisory-senior-cloud-network-infrastructure-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2345593}},{"tool":"search_jobs","arguments":{"company":"subirsinha1811.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2345593},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
