You will be responsible for resolving complex issues, leading optimization efforts, and driving automation and documentation practices to ensure reliable and secure operations.

Responsibilities

• Design and validate Layer 3 network topologies, addressing schemes, and route policies.
• Lead troubleshooting of routing issues involving BGP, OSPF, MPLS, and multicast.
• Monitor network health using telemetry, SNMP, and flow-based tools; respond to anomalies.
• Implement change requests, maintenance windows, and upgrades with minimal service impact.
• Automate recurring network tasks (e.g., provisioning, config backups, audits) using Python, Ansible, or other tools.
• Collaborate with IP architects and security teams to align on policies, segmentation, and access control.
• Participate in capacity planning, traffic analysis, and latency optimization efforts.
• Maintain technical documentation, network diagrams, and SOPs for internal use.
• Mentor junior engineers and contribute to internal knowledge sharing.
• Coordinate with cross-functional teams to support network integration for new services or infrastructure rollouts.

• 6+ years of experience in IP networking and infrastructure support, with at least 4 years in reliability-focused roles.

• Expert-level knowledge of routing protocols (BGP, OSPF, IS-IS) and transport protocols (TCP, UDP, ICMP).
• Proficient in infrastructure automation tools (Ansible, Terraform, Python scripting).
• Experience managing observability platforms (Grafana, Prometheus, ELK, SNMP traps).
• Strong familiarity with network design principles, IP addressing schemes, NAT, ACLs, and traffic engineering.
• Experience with hybrid infrastructure (on-prem + cloud), microservice architectures, and SDN.
• Certifications such as Cisco CCNP/CCIE, Juniper JNCIP/JNCIE, or equivalent.
• Strong documentation and cross-team leadership skills; able to translate technical needs to non-technical stakeholders.
• Familiarity with CI/CD workflows, Git Ops, or containerized networking (CNI, service mesh).
