Senior Cloud Network Infrastructure Engineer

Position Summary :

We are seeking an experienced Cloud Network Infrastructure Engineer to join our cloud engineering team. 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.

Roles and Responsibilities :

SDN & Virtual Switching :

- Architect, maintain, and optimize Open Virtual Switch (OVS) and Open Virtual Network (OVN) dataplanes. Manage OpenFlow pipelines and SDN controllers for automated flow control.

Cloud Infrastructure & Kubernetes :

- 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.

Overlay & Underlay Networking :

- 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).

L2/L3 Routing & Switching :

- Implement and manage dynamic routing protocols (BGP, EVPN, OSPF) for WAN/DC interconnects, ECMP load balancing, and VRRP gateway redundancy.

Network Security :

- 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.

Automation, Telemetry & Lifecycle Management :

- 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.

Technical Requirements & Skill Stack :

Cloud & Virtualization Platforms :

- OpenStack (Neutron, Nova, Metadata Service), OpenStack Ansible, KVM/QEMU, DevStack

Software-Defined Networking (SDN) :

- Open vSwitch (OVS), Open Virtual Network (OVN), OpenFlow, SDN Controllers

Overlay & Encapsulation :

- VxLAN, GENEVE, VLAN (802.1Q)

L2/L3 Protocols & Data Center :

- BGP, EVPN, OSPF, ECMP, VRRP, IPv4/IPv6, ARP/NDP, Ethernet (802.3), STP/RSTP, L3 CLOS, LACP, MCT/vLAG

Cloud-Native & Telemetry :

- Kubernetes, Docker, Kubernetes Controllers, Operator SDK, CRDs, gRPC, Protocol Buffers, Kafka, Numaflow

Security & Packet Inspection :

- IPsec (IKEv2, ESP), IPTables/Netfilter, NFTables, Conntrack

DevOps, Automation & Languages :

- Golang (Go), Python, C, Vagrant, Ansible, Linux CLI, Bash, CI/CD (Jenkins, Git), OpenAPI / REST APIs

Preferred Qualifications :

- 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.

- Deep expertise in Linux networking concepts, packet path traversal, and kernel-level networking subsystems.

- Proven track record with production OpenStack deployments using OVN/OVS as the default networking backend.

- Strong proficiency in Golang, Python, or C with hands-on experience in white-box switch network management applications.

Benefits and Perks :

- Competitive Compensation and Equity

- Medical Healthcare for you and your family

- Hybrid Work Model

- Wellness Benefits

- Professional Development/Global certifications

- Reward and Recognition Programs

- Team Building Activities
