Dear Candidate,

Movate is seeking experienced Network Support Engineers for the support operation in Chennai. The role requires strong 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 practical technical context.

1. 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.

1. GOOD TO HAVE Preferred / Trainable

These are differentiators, not entry barriers for candidates with strong Must Have networking fundamentals. 4.1 SD-WAN / Enterprise WAN
- SD-WAN architecture, edge devices, controllers and orchestrators.
- Underlay/overlay, tunnel establishment, overlay routing and IPsec fundamentals.
- Application-aware routing, path selection, SLA measurement and failover.
- Latency, jitter, packet loss, path conditioning and WAN/ISP troubleshooting.

4.2 Satellite / RF / Telecom
- LEO/MEO/GEO satellite architecture and Ku-/Ka-band awareness.
- RF fundamentals: frequency, wavelength, bandwidth, power, gain, attenuation,



noise and interference.
- Antenna gain, beamwidth, radiation pattern, polarisation, alignment and line of sight.
- Link-budget concepts, free-space path loss, fade margin and SNR.
- Obstruction, weather, installation, cabling, connectors and terminal status.

4.3 AWS / Cloud Networking-Good to have
- AWS VPC, subnets, route tables and network segmentation.
- Transit Gateway attachments, route tables and route propagation.
- Direct Connect and private connectivity concepts.
- BGP-based hybrid/cloud routing and basic cloud connectivity troubleshooting.

4.4 Security
- IPsec VPN fundamentals and tunnel symptoms.
- TLS basics, certificates and encrypted sessions.
- Firewall rules, ACLs, ports and protocol-based filtering.

1. Key Responsibilities

- Troubleshoot customer LAN, routing, WAN/ISP and, after training, SD-WAN, satellite access and cloud connectivity.
- Investigate BGP/OSPF reachability within defined L1 scope.
- Analyse packet captures, monitoring data, logs and device outputs.
- Recognise potential terminal, antenna, RF and satellite-link symptoms and follow diagnostic procedures.
- Maintain incident timelines, evidence, technical notes and customer updates.
- Escalate complex incidents with problem statement, impact, tests performed and findings.
- Participate in training, knowledge checks, lab exercises and production-readiness assessments.

1. Scalability and Growth Potential

- Learning agility: absorbs unfamiliar technologies through structured training and independent study.
- Cross-domain reasoning: correlates RF/satellite, IP networking, routing, SD-WAN and cloud symptoms.
- Complexity progression: potential to move from standard L1 triage to deeper L1/L2 investigation.
- Independent problem-solving: forms hypotheses, tests them and interprets evidence.
- Knowledge contribution: documents repeatable fixes, explains findings and supports peer learning.
