Senior Support Engineer - Linux

U.S. Citizens or Green Card Holders Only (No Sponsorship Available)

Are you a Linux expert who enjoys solving complex production issues and leading technical teams?

We're partnering with a global software company that delivers mission-critical communications platforms to organizations where reliability is essential. They're looking for a Lead Support Engineer to provide technical leadership while supporting enterprise Linux-based applications in production.

This is a hands-on role for someone who excels at root-cause analysis, troubleshooting across multiple technology layers, and mentoring engineers. Rather than building software or administering infrastructure, you'll focus on identifying why production applications fail and driving issues to resolution.

What You'll Do

• Lead and mentor a team of Application Support Engineers
• Serve as the senior technical escalation point for complex production issues
• Troubleshoot Linux-based applications using command-line tools, logs, and system traces
• Perform root-cause analysis across application, operating system, network, and infrastructure layers
• Investigate SIP/VoIP and communication platform issues
• Analyze network traffic using Wireshark
• Partner with customer engineering teams to resolve critical issues
• Collaborate with development teams by documenting defects and technical findings
• Develop Methods of Procedure (MOPs) for upgrades, maintenance, and production changes

What We're Looking For

• 7+ years supporting enterprise applications in Linux environments
• Strong hands-on experience with Red Hat Linux or similar distributions
• Advanced Linux troubleshooting and command-line expertise
• Experience analyzing logs, traces, and application performance
• Solid networking knowledge (TCP/IP, DNS, routing, troubleshooting)
• Experience supporting SIP or VoIP technologies
• Ability to interpret Wireshark captures
• Excellent communication skills and experience working directly with customers
• Previous technical leadership or mentoring experience

Preferred Qualifications

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

If you're looking for a role where you can combine deep Linux troubleshooting expertise with technical leadership while supporting mission-critical communication systems, we'd love to hear from you.
