Position Overview

Movate is seeking experienced Network Support Engineers for the support operation in Chennai. The role requires robust IP networking fundamentals, practical routing knowledge and structured, evidence-led troubleshooting. Engineers will investigate connectivity incidents across customer networks and, following training, SD-WAN, satellite access and cloud connectivity. Candidates must analyse packet-level evidence, document findings, communicate clearly and escalate incidents with useful technical context.

2. Experience:(Any one)

- 3-5 years of relevant technical experience in network support, enterprise networking, ISP, NOC or managed network services.
- Pathway A: CCNP-level networking capability, including routing, troubleshooting, SD-WAN, BGP and OSPF.
- Pathway B: CCNA-level networking capability, including networking fundamentals, troubleshooting, BGP and OSPF.
- Pathway C:CCNA/CCNP: RF/satellite, Vsat,Satellite communicaton
- CCNA/CCNP certification preferred; practical competency demonstrated in interview is essential.

3.1 Core Networking Fundamentals

- OSI/TCP-IP models, encapsulation/decapsulation and end-to-end packet flow.
- IPv4/IPv6 addressing, subnetting, CIDR, route summarisation and longest-prefix match.
- Routing and switching, VLANs, access/trunk ports and inter-VLAN routing.
- ARP, ICMP, DNS, DHCP, NAT, default gateways and basic ACL concepts.
- TCP/UDP, ports, three-way handshake, MTU, MSS, fragmentation and Path MTU Discovery fundamentals.
- Interpret interface status/counters, routing tables, logs and network diagrams.





3.2 OSI-Layer Troubleshooting

- Structured, evidence-led fault isolation from Layer 1 through Layer 7.
- Validate physical connectivity, power, cabling, interface errors and link status.
- Investigate VLAN, MAC learning, ARP and Layer 2 forwarding issues.
- Validate addressing, gateway reachability, routing, NAT and ACL behaviour.
- Investigate TCP establishment, retransmissions, resets, DNS and application reachability.
- Differentiate LAN, customer edge, WAN/ISP, satellite access, cloud and application fault domains.
- Document tests, observations, evidence, impact, likely fault domain and next action.

3.3 BGP and OSPF

- BGP architecture, AS numbers, eBGP/iBGP and neighbour relationships.
- BGP state machine and troubleshooting failed or unstable peerings.
- Route advertisement/withdrawal, prefix filtering, propagation and best-path fundamentals.
- BGP attributes including local preference, AS path and MED.
- OSPF neighbour formation, adjacency states, areas, router ID, network types and cost.
- OSPF LSA and link-state database concepts at troubleshooting level.
- Investigate missing routes, route selection, reachability and convergence.

3.4 TAC / Customer Handling

- Explain incident investigation and gather relevant evidence.
- Communicate technical findings clearly and professionally.
- Maintain accurate incident notes, timelines, actions and handover details.
- Understand prioritisation, escalation and service-level discipline.
- Follow runbooks and security policies in the agreed 247 operating model.
