About the Role

We’re seeking a hands-on Network Deployment Engineer to design, implement, and optimize network deployments across enterprise and data center environments. The ideal candidate combines deep routing/switching expertise with modern NetDevOps and automation practices to deliver repeatable, reliable outcomes at scale.

Key Responsibilities

• Plan, build, and deploy network infrastructure across campus, WAN, and data center environments.
• Implement VxLAN/EVPN overlays, spine–leaf architectures, and L2/L3 segmentation.
• Configure and optimize routing & switching (BGP, OSPF, eBGP/iBGP, ECMP, STP alternatives).
• Use NetDevOps practices (Git, CI/CD, testing) to version, validate, and promote network changes.
• Develop and maintain automation (e.g., Python, Ansible, Terraform) for repeatable deployments.
• Integrate with VMware NSX or equivalent SDN for micro-segmentation and overlay networking.
• Create and maintain architecture diagrams, runbooks, and deployment documentation.
• Conduct pre-deployment validations, cutovers, and post-deployment optimization.
• Troubleshoot complex L2/L3/VNI issues and drive root-cause analysis.
• Collaborate with Security, Platform, and Cloud teams to ensure resilient, compliant designs.
• Provide knowledge transfer and support to operations for smooth handover.

Requirements (Must-Have)

• Expert in Routing and Switching (enterprise and data center).
• Strong knowledge of VxLAN and EVPN (control-plane and data-plane, multi-tenancy).
• Proficient in NetDevOps practices (Git workflows, CI pipelines, config-as-code).
• Experience with Automation tools (e.g., Ansible, Python, Terraform) or VMware NSX.

Preferred Qualifications (Nice-to-Have)

• Experience with major vendor ecosystems (e.g., Cisco NX-OS/IOS-XE, Arista EOS, Juniper) and fabric controllers (e.g., NDFC, Arista CVP, Apstra).
• Exposure to observability/telemetry (gNMI, streaming telemetry, NetFlow/IPFIX) and NPM/NDR.
• Familiarity with cloud networking (AWS/Azure/GCP), hybrid connectivity, and SD-WAN.
• Scripting proficiency (Python) for validation, templating (Jinja2), and API integrations (REST/GraphQL).
• Knowledge of network security (ACLs, micro-segmentation, firewalling, zero trust).
• Relevant certifications (e.g., CCNP/CCIE, JNCIP/JNCIE, VCP-NV, Arista ACE).
