Voice AI Integration Lead (SIP / Telephony)

Connected IT has exclusively partnered with a pioneering technology scale-up that builds enterprise Voice AI systems. Their cutting-edge platform connects AI agents and agent-assist technologies directly into real contact-centre voice environments. They are currently undergoing significant growth and are expanding their dedicated engineering hub in Manchester.

The Role Our client is seeking a senior, hands-on Voice AI Integration Lead to act as the technical bridge between complex enterprise telephony systems and production AI.

This is not a traditional telecoms engineering / operations job, a generic PBX administration role, or a software developer position. You will lead the design, build, and troubleshooting of integrations that make real-time AI voice services function seamlessly in customer environments. Beyond project delivery, you will dedicate a portion of your time to internal platform engineering, using what you learn from deployments to help ensure a resilient, highly reusable, and exceptionally low-latency real-time voice infrastructure.

Key Responsibilities

• Lead technical discovery sessions and design SIP/SIPREC and direct integration approaches for enterprise contact-centre environments.
• Act as the senior technical escalation point to diagnose and resolve complex SIP, RTP/media, SBC, TLS/SRTP, NAT/firewall, and interoperability issues.
• Represent the business credibly in technical design workshops and production readiness discussions directly with external enterprise client teams.
• Drive continuous improvements across the media path to reduce end-to-end latency, optimising transcoding, jitter buffering, and AI-agent response times.
• Convert one-off customer integrations into reusable platform capabilities, adapter patterns, and automated diagnostics.

What You Need to Succeed (Core Requirements)

• Deep, practical knowledge of SIP signalling and troubleshooting (e.g. SDP negotiation, codec negotiation, packet loss, and jitter).
• Hands-on experience integrating, configuring, and operating Session Border Controllers (SBCs) such as AudioCodes, Ribbon, Oracle, or Cisco CUBE.
• Proven experience working with voice platforms such as Cisco, Avaya, Alvaria, Genesys, NICE, or Amazon Connect.
• Confidence reading and diagnosing network issues using packet captures and traces via tools like Wireshark, SIPp, Homer, or vendor trace tools.
• Full right to work in the UK (no sponsorship is available), the ability to pass a DBS check, and the ability to travel to UK / Ireland on occasion for work purposes without visa restrictions.
• Excellent communication skills and the ability to engage with both technical and non-technical stakeholders.

Nice to Haves (Training Provided)

• Previous exposure to AI, LLMs, STT/TTS, or voicebots. Our client highly values deep, real-time voice and telephony expertise over day-one AI knowledge; they will provide comprehensive training on their AI stack.
• Experience implementing SIPREC in live contact-centre environments.
• Scripting or automation experience (e.g., Python, Node.js, Bash, Terraform).
