Our client is a global software company that develops communication platforms used in mission-critical environments. Their customers include public safety organizations, transportation companies, utilities, defense organizations, and large enterprises where reliable communication is essential.

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

Required Qualifications:

  • 7+ years of experience supporting production applications in Linux environments
  • Strong hands-on experience with Red Hat Linux or similar Linux operating systems
  • Advanced Linux command-line troubleshooting skills
  • Experience analyzing logs, traces, and system performance issues
  • Strong networking fundamentals (TCP/IP, DNS, troubleshooting)
  • Experience with SIP or VoIP technologies
  • Ability to analyze Wireshark captures
  • Strong customer-facing communication skills
  • Previous experience as a Lead Engineer, Technical Lead, or mentor preferred

Preferred Experience:

  • Telecommunications, VoIP, IMS, or carrier-grade communication platforms
  • Linux scripting
  • VMware vSphere
  • Diameter protocol
  • Cisco IOS
