Senior Software Engineer – Network Automation

Infrastructure Engineer

• Architect and Evolve the Private Cloud: Own the end-to-end architecture of our OpenStack-based private cloud (Nova, Neutron, Cinder, Glance, Keystone, Placement, Octavia, Designate) across multiple regions and data centers.
• Lead Ceph at Scale: Design, deploy, and operate large Ceph clusters, tiering, replication strategy, performance tuning, and lifecycle upgrades.
• Operate Bare Metal as a Service: Architect and operate an Ironic-based BMaaS platform integrated with OpenStack and/or Kubernetes, covering hardware enrollment, inspection, image deployment, network provisioning, and lifecycle management at fleet scale.
• Data Center Expansion: Lead the technical design of new data center buildouts, and bare-metal automation, defining reference architectures, hardware standards, and capacity models.
• Infrastructure as Code: Set the standards for IaC across the platform using Terraform, Ansible, Packer, and configuration management — including OpenStack lifecycle tooling (e.g. Kolla-Ansible, OpenStack-Ansible, Charmed OpenStack, etc).
• Networking Architecture: Define the SDN strategy (OVN/OVS), tenant networking, provider networks, BGP/EVPN integration with the underlay, and high-performance datapaths (SR-IOV, DPDK) for latency- and throughput-sensitive workloads.
• Kubernetes on Bare Metal: Architect Kubernetes platforms running on Ironic-provisioned hardware and OpenStack, including service mesh, CNI selection, and integration with Ceph CSI for persistent storage.
• Performance, Capacity, and Cost: Drive capacity planning, performance benchmarking, and TCO modeling for compute, storage, and bare-metal fleets — ensuring efficient resource utilization and predictable scaling.
• Reliability and Operability: Partner with the SRE team to define SLIs/SLOs for platform services, design failure domains, validate disaster recovery, and ensure operational maturity of every new component introduced.
• Security and Compliance: Work closely with Security to harden the platform end-to-end - secure boot, image signing, IAM (Keystone federation, OIDC, LDAP/AD), tenant isolation, and compliance with CIS, ISO 27001, and GDPR.
• Technical Leadership: Mentor senior and mid-level engineers, lead design reviews, write RFCs and architecture decision records, and represent Infrastructure in cross-functional technical forums.
• Support and Troubleshooting: Act as the deepest escalation point for the platform; participate in on-call for critical incidents, lead complex root-cause investigations across compute, storage, and network layers.
