Bonus Points: + Carrier Expertise: Direct experience with carrier-to-carrier SIP interconnects and carrier-grade voice network design. + Routing & Databases: Experience with Least Cost Routing and complex routing logic. + Voice Security: Familiarity with TLS, SRTP, and regulatory compliance including STIR/SHAKEN and E911. + Virtualized Infrastructure: Experience deploying voice services in containerized or cloud-native environments. + Networking: Solid knowledge of IP, DNS, and routing protocols. ## Description We are seeking a Senior VoIP Engineer with a modern engineering mindset to join Bandwidth's Network Operations team. While you possess deep expertise in SIP and carrier-grade environments, you view infrastructure through the lens of Software Reliability Engineering (SRE). This role is critical for ensuring reliable, secure, and automated SIP connectivity across multiple carrier platforms and enterprise environments. What You'll Do: + Platform Automation: Design and implement automation to reduce operational burden, replacing manual workflows with scripting and Infrastructure as Code (IaC). + Voice Orchestration: Use tools like Ansible/AWX, Github, and Terraform to automate the provisioning and scaling of voice services and carrier interconnects. + Carrier Interconnect Strategy: Design, deploy, and maintain SIP solutions with global carriers to ensure reliability, compliance, and optimal routing. + Advanced Observability: Act as the highest-level escalation point for complex SIP/RTP problems. Use advanced tools like Empirix, Wireshark, SIPp, and HEPIC to analyze call flows and media streams. + System Integration: Collaborate with R&D teams to integrate SIP services from SBC edge to custom voice core. ## Related Videos - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [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) - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Embracing the Hybrid Cloud: Unlocking Success with Ansible](https://www.wearedevelopers.com/videos/932-embracing-the-hybrid-cloud-unlocking-success-with-ansible) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The CAMARA Project: How Telcos Collaborating Improves Developer Experience](https://www.wearedevelopers.com/magazine/671-the-camara-project-how-telcos-collaborating-improves-developer-experience) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [I have a stream!
