## Description

They are seeking a Lead Application Support Engineer with strong Linux expertise to support their communication platform after deployment to customers. This is a hands-on technical leadership role focused on troubleshooting complex production issues, performing root-cause analysis, and guiding a team of support engineers.

The ideal candidate is someone who is highly comfortable working in Linux environments, using command-line tools, reviewing logs and traces, and troubleshooting issues across the application, operating system, and customer infrastructure layers.

This is not a traditional Linux administrator, network engineer, or software development role. This position requires someone who can investigate why a production application is failing and determine whether the issue is within the application, Linux environment, network, or an integrated system.

Responsibilities:

 * Lead and mentor a team of Application Support Engineers while serving as a senior technical escalation point
 * Troubleshoot complex production issues within Linux-based application environments
 * Analyze logs, traces, and system behavior using Linux command-line tools
 * Perform root-cause analysis across application, OS, and networking layers
 * Troubleshoot SIP and communication platform issues
 * Analyze Wireshark traces and network captures
 * Work directly with customer engineering teams to resolve technical issues
 * Collaborate with development teams by identifying bugs and providing technical findings
 * Create MOPs (Methods of Procedure) for production changes, upgrades, and maintenance activities
