We are looking for a Senior VoIP PBX Engineer who can confidently own complex telephony environments and drive improvements in reliability, security, and call quality.
Required experience & skills
- Strong expertise in VoIP/PBX engineering and SIP fundamentals (signaling, session behavior, routing, and troubleshooting).
- Hands-on experience administering and supporting PBX systems in production, including configuration, upgrades, and operational hardening.
- Proven ability to diagnose call issues using logs, traces, and network/media analysis (e.g., codec/negotiation, RTP behavior, NAT traversal).
- Solid understanding of networking concepts relevant to VoIP (DNS, TLS/SRTP considerations, firewalls, QoS/latency impacts, and SIP/RTP port flows).
- Experience integrating PBX features such as voicemail, IVR, routing rules, and call handling into real-world workflows.
- Comfort working with incident management: triage, root-cause analysis, corrective actions, and prevention.
Strong traits
- We expect you to communicate clearly with technical and non-technical stakeholders during troubleshooting and change windows.
- We value ownership: you prioritize stability, anticipate failure modes, and follow change management discipline.
- We look for structured problem-solving and good judgment under time pressure.
- We appreciate documentation habits and continuous improvement thinking.
If you’re experienced in building dependable VoIP systems and enjoy hands-on engineering as well as operational excellence, we’d like to meet you.
