Job description

Job Summary

We are looking for a hands‑on Senior Network Engineer with a minimum of 5 years of experience. The ideal candidate should have worked as a Network Engineer for an IT infrastructure service provider or IT solutions integration company in the past. The candidate is expected to understand customer requirements and pain areas through call, email, or meeting, develop an innovative Network/Network Security solution, conduct onsite or remote POC, and pitch to different customers as required. After acceptance, the candidate should implement the plan, train the client team, coordinate with the client, build or polish documentation, and hand over the setup. The candidate should also train internal team members, grow the internal knowledge base, and lead the Network Practice for the company. In simplest terms, imagine visiting one of 600+ customers when a customer is facing a problem they cannot resolve internally: understand the problem, pitch a solution, implement it, and move on to the next problem. You will encounter different problems, devices, and architectures at each client, providing unparalleled learning and growth with fellow passionate team members.

• Deal with all types of network‑related incidents to ensure that Service Level Agreements with customers are met.
• Build and maintain working relationships with key interconnect partners and customers.
• Provide 24×7 support on request from the customer as an exception; this support may require travel to customer locations, with ad‑hoc calls minimal and most calls planned for down‑time or maintenance.
• Prefer strong working knowledge in vulnerability assessment, network audits, and throughput testing.
