Column Case Management is looking for a senior, hands-on IT infrastructure and application performance expert who can troubleshoot intermittent large-file upload and video download issues across the entire stack rather than focusing on only one component. This Candidate should have a solid understanding of the following Technologies listed below.  Tools: WireShark tcpdump Cisco Firewalls Windows Server & Linux PostgreSQL  browser developer tools (HAR analysis) Useful Knowledge: Hostname-versus-Direct-IP Differences ISP or Carrier-Level Throttling (Traffic Shaping) General computing knowledge which would help diagnose the issue TCP/IP performance analysis TLS/HTTPS The issue is intermittent, which has made it difficult to reproduce consistently: the same files may complete normally during one test and take 20–60 minutes or more during another, while one reported a one-hour transfer dropped to approximately 10 minutes when the user accessed the application through the direct public IP instead of the DNS hostname. We need someone capable of leading a coordinated end-to-end test with an affected user, browser HAR capture, client and server packet captures, Cisco firewall captures, Linux/server performance monitoring, application logs, storage metrics, and ISP-path validation collected during the same good and bad test windows, then correlating the evidence and identifying exactly where the delay begins.
