This position offers the opportunity to work on cutting-edge AI infrastructure projects while partnering with engineering teams, customers, and data center operations personnel to deliver reliable and repeatable deployments.
Responsibilities
- Perform cluster bring-up activities using approved deployment methodologies, automation workflows, and configuration standards.
- Design and validate large-scale Ethernet fabrics utilizing CLOS and leaf-spine architectures.
- Develop IP addressing plans and validate network topology, connectivity documentation, and infrastructure designs.
- Build, provision, test, and validate network switch configurations in lab and production environments.
- Configure and troubleshoot inter-node networking, including RoCE-enabled environments.
- Develop automation scripts and tooling using Python and Ansible.
- Troubleshoot network, hardware, cabling, and configuration issues during deployment and operational support activities.
- Partner with data center technicians and remote-hands teams to coordinate remediation efforts.
- Document incidents, troubleshooting findings, root cause analysis, and deployment outcomes.
- Create deployment records, configuration artifacts, validation reports, and operational handoff documentation.
- Communicate project status, risks, blockers, and technical updates to stakeholders and cross-functional teams.
Required Qualifications
- 7+ years of experience with Ethernet switching, routing, and TCP/IP networking.
- Expert-level experience designing, implementing, and troubleshooting data center leaf-spine/CLOS architectures.

Requirements
Sr. Network Automation Engineer - Hybrid on site 2 days/week Santa Clara, CA About the Role We’re seeking a hands-on Infrastructure Systems Developer who thrives in building full-stack systems with a focus on network automation. This is not your traditional network engineering role — we’re looking for someone who comes from the DevOps or systems development world and has ventured into networking by building tools, platforms, and automation frameworks that interact with network infrastructure. You will own the architecture and development of a full-stack system that ingests, stores, and acts on network telemetry and configuration data — from backend frameworks to frontend UI to device interaction and automation. Key Responsibilities Design and architect an end-to-end automation system for network configuration and telemetry. Choose and implement the right technologies: Database: SQL, NoSQL, or MDM SQL solutions. Backend: Python (FastAPI, Flask), Go, or similar. Frontend: React, Vue, or modern JS framework. Build integrations with CI/CD pipelines (e.g., Jenkins). Implement configuration management and telemetry collection using Ansible, SaltStack, or similar tools. Create APIs and services to interface with network devices. Ensure scalable data storage and retrieval for network metadata and telemetry. Collaborate with network engineers, DevOps, and security teams. Requirements Strong programming skills in Python, Go, or equivalent languages. Experience designing and building production-level infrastructure systems. Deep understanding of system architecture and software lifecycle. Familiarity with network automation concepts and tools, even if not a traditional network engineer. Hands-on experience with: CI/CD: Jenkins or equivalent. Config Management: Ansible, Salt. Database systems: SQL and NoSQL (MongoDB, PostgreSQL, etc.). Frontend frameworks: React, Vue, or similar. Comfort working across the full stack and owning the entire lifecycle of a system. Nice to Have Exposure to network protocols and device-level APIs (e.g., NETCONF, RESTCONF). Experience in telemetry collection, parsing, and visualization. Contributions to open-source DevOps or automation tools. Experience with MDM/metadata modeling.
