Platform9: Private Clouds Made Easy

Platform9 is the leader in simplifying enterprise Private Clouds. Founded by a team of VMware cloud pioneers, we are dedicated to transforming IT operations. Our flagship product, Private Cloud Director, turns your existing hardware into a full-featured, future-ready private cloud. We innovate across what we build and how we deliver it, staying focused on a next-generation, open private cloud while holding ourselves to one standard: exceptional customer outcomes.

Enterprises are selecting Platform9 to replace legacy virtualization because it eliminates operational risk and complexity. Private Cloud Director is designed for the experienced infrastructure team, offering a familiar GUI experience for managing VMs and containers, seamless integration with your existing hardware and third-party storage, and critical enterprise features (HA/DR, scale, reliability) built-in. This enables IT teams to gain robust API control and a user experience they trust—rooted in customer obsession and an owner's mindset. We share context quickly and candidly to keep decisions moving.

With over 30,000 nodes in production at some of the world's largest enterprises, including Cloudera, EBSCO, Juniper Networks, and Rackspace, Platform9 is the proven path to achieving true vendor independence and operational consistency. We are an inclusive, globally distributed company backed by prominent investors, supported by a partner ecosystem of resellers, systems integrators, MSPs, and technology vendors committed to driving private cloud innovation and efficiency. Our values—innovation, customer obsession, ownership, radical candor, and excellence—guide how we build and support every deployment.

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. You will manage virtual switching platforms, overlay networking, and L2/L3 dynamic routing to ensure seamless connectivity and robust security across our private cloud infrastructure.

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.
• Self-starter with strong problem-solving skills, analytical thinking, and excellent written/verbal communication in dynamic environments.

To succeed in this role, you will need to be a team player with a strong sense of ownership for your work and a passion for working in a data-driven organization.
