  • Collaborate across Python and C/C++ codebases to maintain and enhance the call-handling engine.
  • Integrate and maintain components via cmake/make; manage AIB (Application Interface Binary) builds and packaging.
  • Troubleshoot OS-level dependency and build failures on RHEL8; ensure continuous delivery of release artifacts.
  • Monitor and debug SIP signaling interactions with SBC, including call drops and negotiation errors.
  • Validate end-to-end voice call flows across cloud, OS, and telephony layers.
  • Support infrastructure automation workflows, CI/CD pipelines, and production debugging.
  • Collaborate with telephony engineers, DevOps, and product teams to ensure high rise-time connector stability.
  • Communicate clearly and effectively with technical and non-technical stakeholders.
