This is not a general IT support role - you'll be diagnosing complex SIP signaling issues, call flow problems, and Linux-based VoIP services under real production conditions. If you enjoy digging into packet captures, tracing call failures, and working at the intersection of Linux, networking, and voice, this role is built for you. What You'll Do * Troubleshoot SIP call flows, registration issues, and signaling failures * Analyze pcap/Wireshark captures to isolate VoIP and network issues * Investigate incidents across Linux OS, VoIP applications, and network layers * Work directly in production to resolve service-impacting voice issues * Collect and analyze logs, traces, and system metrics from Linux servers * Support and maintain SIP-based communication platforms * Implement config changes, patches, and system updates * Partner with engineering to identify defects and improve platform stability * Document root cause analysis, fixes, and operational procedures * Participate in maintenance windows and production changes ## Related Videos - [How I saved 200K/yr in direct costs writing 0 code lines in K8s](https://www.wearedevelopers.com/videos/1055-how-i-saved-200k-yr-in-direct-costs-writing-0-code-lines-in-k8s) - [WebAssembly: The Next Frontier of Cloud Computing](https://www.wearedevelopers.com/videos/972-webassembly-the-next-frontier-of-cloud-computing) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Getting under the skin: The Social Engineering techniques](https://www.wearedevelopers.com/videos/38-getting-under-the-skin-the-social-engineering-techniques) - [Generating code with Angular schematics](https://www.wearedevelopers.com/videos/129-generating-code-with-angular-schematics) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [How to Ensure a Reasonable Salary Before an Interview](https://www.wearedevelopers.com/magazine/322-how-to-ensure-a-reasonable-salary-before-an-interview) - [Tips on mastering remote job interviews](https://www.wearedevelopers.com/magazine/23-tips-on-mastering-remote-job-interviews)
