About the job

We are seeking a customer service–oriented Network and Security engineer with 8-10+ years of hands-on experience in enterprise and service provider networking. This role is primarily focused on routing, switching, firewalling, load balancing, virtualized network services, and architect-level design work (HLD/LLD documentation for large-scale enterprise and cloud customer service deliveries).

The successful candidate will be a rockstar in core networking who can both design and operate complex network infrastructures, while also leading customer-facing design discussions and producing professional documentation. Additional exposure to IPv6, VXLAN/NSX-T, and Cisco ACI is considered a strong plus.

Key Responsibilities

  • Architect, design, and document enterprise network solutions with detailed HLD (High-Level Design) and LLD (Low-Level Design) diagrams for large-scale enterprise and cloud customers.
  • Design and implement core network systems by defining configurations, overseeing installation, and enforcing standards.
  • Deploy and manage virtualized network services, including virtual firewalls, routers, and load balancers across private cloud and enterprise environments.
  • Optimize and secure network performance through proactive monitoring, troubleshooting, and upgrades.
  • Collaborate with peers and architects on advanced routing/switching and network optimization strategies.
  • Manage and maintain firewall environments, including segmentation, policies, and threat prevention.
  • Architect and support load balancing solutions for mission-critical workloads.
  • Act as a Tier-2/3 escalation point for complex networking issues.
  • Engage directly with enterprise customers to gather requirements, present designs, and ensure delivery excellence.

Qualifications

  • 8–10+ years of enterprise and service provider networking expertise, focused on routing, switching, firewalling, load balancing, and virtualized network services.
  • Proven ability to produce professional HLD/LLD designs and present them to enterprise/cloud customers.
  • Deep knowledge of routing protocols (BGP, OSPF, static/dynamic routing).
  • Deep knowledge of the TCP/IP stack with the ability to troubleshoot at the packet level using Wireshark or similar tools.
  • Hands-on experience with physical and virtual firewalls (Juniper SRX, Cisco ASA/FTD, Palo Alto, Fortinet).
  • Strong background with physical and virtual load balancers (F5, Citrix ADC/NetScaler, A10).
  • Experience deploying virtual routers in enterprise or cloud environments.
  • Solid understanding of VLANs, trunking, STP, Nexus VPC, and enterprise switching (Cisco Nexus, Arista, etc.).
  • Strong knowledge of VPN technologies (IPSec, SSL VPN).
  • Experience working with global enterprise customers (North America, Europe, or APAC).
  • CCNP required; CCIE strongly preferred.
  • Excellent communication and customer-facing troubleshooting skills.
  • Ability to work independently and as part of a collaborative global team.
  • Good understanding of Azure networking features and platform to maintain current Azure deployments as well as design and deploy new ones.
