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.

What You'll Be Doing

• 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

Desired Experience

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

Ideal Background

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.

Interview Process

• 1 / 2 stage interview - Depending on manager availability

• Immediate start available
