Job summary

Infotree Global Solutions in Austin, TX seeks a senior network engineer to design and evolve network architectures for large-scale Private Cloud OpenStack and HPC environments. You will develop scalable Leaf-Spine designs using BGP, EVPN, VXLAN, and ECMP, and integrate with OpenStack Neutron/OVN/ML2.

The role demands deep expertise in high-performance compute networking, SR-IOV/DPUs, Python/Ansible/Terraform automation, and applying SRE principles for reliable service delivery.

Responsibilities

• Design networking for high-performance compute, storage and latency-sensitive engineering workloads.
• Evaluate technologies including SR-IOV, SmartNICs, DPUs and high-performance Ethernet.
• Integrate physical network infrastructure with OpenStack networking services including Neutron, OVN and ML2.
• Strong experience designing and supporting high-performance or large-scale compute environments using RoCE, RDMA or Infiniband in a Cisco NX-OS and/or Arista EOS.
• Deep understanding of BGP routing and network architectures, Leaf-Spine network, Layer 2 and Layer 3, ECMP, EVPN and VXLAN and network resilience.
• With exposure to newer technologies such as SmartNICs, DPUs & NVMe over-Fabrics.
• Practical experience of OpenStack network services and developing integrated network automation and API driven interfaces.
• Strong HPC network observability, troubleshooting and performance tuning skills.
• Strong Linux knowledge and Kubernetes networking.
• Exposure to SR-IOV and DPDK.
• Demonstrable hands-on Python, Ansible and Terraform experience.
• Using SRE principles in the creation of SLI/SLO and error budgets
