Initial 6 Month Contract

We are looking for a Senior AI Voice Engineer to help build and scale a production-grade AI voice platform for a major UK financial services organisation.

This is not a proof-of-concept role.

The business has already built initial Python-based prototypes and is now looking for an experienced contractor to take the solution into production, helping define the architecture, challenge technical decisions, and build a scalable platform capable of handling real customer interactions.

You'll work directly with senior stakeholders and have significant influence over both the technical direction and implementation approach.

• Designing and building production-grade AI voice agent solutions

• Developing scalable Python services and APIs

• Working with speech-to-text (STT), large language models (LLMs) and text-to-speech (TTS) technologies

• Evaluating and recommending architecture decisions across voice AI platforms

• Building resilient, low-latency conversational systems

• Integrating AI voice capabilities into existing customer service workflows

• Defining monitoring, observability and performance standards

• Helping transition existing prototypes into a secure, scalable production platform

We're particularly interested in engineers with commercial experience of one or more of:

• Azure Voice Live

• ElevenLabs

• Deepgram

As well as:

• Expert Python development

• Real Time AI systems

• LLM-powered applications

• Conversational AI platforms

• API design and integration

• Cloud-native architecture

• Production deployment and scalability

• Voice, speech or contact centre technology

You may have worked as:

• AI Voice Engineer

• Conversational AI Engineer

• Speech AI Engineer

• AI Platform Engineer

• Senior Python Engineer

• Applied AI Engineer

Most importantly, we're looking for someone who has built and deployed AI voice solutions before and can help shape the architecture rather than simply implement requirements.

• 1/2 stage interview - Depending on manager availability

• Immediate start available
