Senior Network Engineer – Infrastructure, Security & Cloud Integration

Roles & Responsibilities

Job Summary :

We are seeking a seasoned Senior Network Engineer with extensive experience in designing, implementing, and maintaining mission-critical network infrastructure across hybrid environments. The ideal candidate will have deep technical expertise in enterprise routing and switching, network security, cloud-based networking (AWS / Azure / GCP), automation (Ansible, Python), and next-generation firewalling. This role demands a proactive and strategic thinker capable of delivering low-latency, high-availability network solutions while ensuring scalability and compliance with global security standards.

Responsibilities :

• Architect and implement highly available, scalable, and secure Layer 2 / 3 network solutions across multiple data centers, branch locations, and cloud environments.
• Lead the migration of on-prem infrastructure to cloud-native networking architectures (e.g., AWS VPC, Transit Gateway, Azure VNets, etc.).
• Design and optimize BGP / OSPF / MPLS / EVPN-based topologies for multi-homed ISP connectivity, WAN edge, and internal traffic engineering.
• Provide Tier 3 / 4 level escalation support for complex networking incidents involving switching loops, asymmetric routing, DNS failures, etc.
• Analyze pcap dumps, NetFlow, SNMP, and syslogs to perform deep-dive root cause analysis.
• Perform regular network performance assessments and latency optimization across global circuits.
• Design and enforce zero-trust network access (ZTNA) and microsegmentation policies using tools like Cisco ISE, Palo Alto, or Fortinet.
• Collaborate with SecOps to implement network access controls, IDS / IPS, VPNs, and Next-Gen Firewalls.
• Maintain compliance with regulatory standards such as ISO 27001, PCI-DSS, SOX, and HIPAA, including network audit preparation and documentation.
• Automate network provisioning and configuration using Ansible, Python (Netmiko / NAPALM), or Terraform.
• Integrate network telemetry with monitoring systems (e.g., SolarWinds, Zabbix, Prometheus, Grafana) for proactive alerting and capacity planning.
• Develop custom scripts and playbooks to streamline repetitive tasks and enforce configuration compliance.
• Work closely with cross-functional teams including CloudOps, DevOps, Security, and Application teams to ensure seamless connectivity.
• Contribute to the development of network engineering standards, runbooks, and architectural documentation.
