What We Are Looking For:

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 and Terraform to automate the provisioning and scaling of voice services and carrier interconnects.
• Open Source & Interoperability: Conduct detailed interoperability testing between carrier platforms and open-source SIP implementations (e.g., Kamailio, OpenSIPS), resolving signaling mismatches and codec issues.
• Carrier Interconnect Strategy: Design and maintain SIP trunking solutions with multiple 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 Wireshark, SIPp, and HEPIC/Homer to analyze call flows and media streams.
• System Integration: Collaborate with network and security teams to integrate SIP services through proxy servers and modern routing policies.
• Documentation & Mentorship: Maintain "Documentation as Code," including SIP call flow diagrams and interconnect standards, while providing guidance to junior staff on modern troubleshooting methodologies.

What You Need:

• Experience: 5+ years of hands-on VoIP engineering experience, with a heavy emphasis on carrier-grade SIP environments.
• SIP Mastery: Expert-level knowledge of SIP signaling (INVITE, BYE, etc.), SDP negotiation, and RTP/RTCP.
• Automation Toolkit: 3+ years of proficiency in Python, Bash, or Ansible for automating provisioning and troubleshooting workflows.
• Infrastructure as Code: Experience using IaC tools to manage infrastructure at scale.
• SIP Proxies: Hands-on experience with open-source SIP proxies (e.g., Kamailio, OpenSIPS) alongside traditional SBCs (e.g., Ribbon, Oracle/Acme Packet).
• Linux/OS: Strong Linux administration skills for VoIP application performance and system troubleshooting.
• Diagnostics: Proficiency with diagnostic tools such as Wireshark, sngrep, and Homer/HEP.

Bonus Points:

• Carrier Expertise: Direct experience with carrier-to-carrier SIP interconnects and SS7-to-SIP interworking.
• Routing & Databases: Experience with ENUM, LNP, and complex routing logic.
• Voice Security: Familiarity with TLS, SRTP, and regulatory compliance including STIR/SHAKEN and E911.
• Cloud Infrastructure: Experience deploying voice services in containerized or cloud-native environments.
• Networking: Solid knowledge of IP, DNS, and routing protocols.
