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:
- ElevenLabs
- Deepgram
As well as:
- 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:
- Conversational AI Engineer
- Speech AI Engineer
- Senior Python 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.
