At H&F; Communicatrions, inc, we build and maintain reliable voice communication systems that our customers can depend on. As a Senior VoIP PBX Engineer, we focus on designing, implementing, and operating our PBX and VoIP infrastructure end-to-end-helping ensure high availability, secure integrations, and consistent call quality. You will own key projects across SIP trunking, call routing, voicemail/IVR, conferencing, and integrations with existing telephony services, while improving monitoring, troubleshooting workflows, and platform resilience for production environments.

Apply to this job opportunity at getonbrd.com.

Functions

In this role, we want you to lead the engineering and operational work that keeps our VoIP PBX environment stable, secure, and scalable.

- Design, deploy, and maintain VoIP PBX solutions (e.g., SIP-based systems), including core call flows, routing, and dial plans.
- Configure and manage SIP trunks, inbound/outbound calling, number normalization, and carrier interop.
- Implement and tune voicemail, IVR, conferencing, hunt groups,



call queues, and call recording workflows (where applicable).
- Ensure reliability by building and refining monitoring, alerting, and log/trace practices for call quality and uptime.
- Troubleshoot production issues end-to-end (SIP signaling, RTP/media flow, codecs, NAT/firewalls, latency, and configuration drift).
- Collaborate with networking, security, and application stakeholders to integrate PBX services with external systems.
- Harden systems through secure configuration baselines, access controls, and vulnerability awareness.
- Document architectures, runbooks, and standard operating procedures to improve team velocity and reduce outages.
- Mentor team members and contribute to technical design reviews and best-practice improvements.

Description

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.

Desirable

- Experience with additional telephony/communication tooling such as SBCs, SIP proxies, or related mediation components.
- Knowledge of security best practices for voice systems (SRTP/TLS usage, certificate management, and hardened configuration strategies).
- Familiarity with automation or infrastructure-as-code approaches for repeatable deployments and configuration management.
- Experience collaborating with cloud or hybrid environments for identity, integrations, or monitoring.

Benefits

Benefits and work arrangements will be discussed during the interview process.
