Headquartered in Billericay, Essex, United Kingdom, the company operates across key international markets throughout Europe and North America.

Job title - Lead AI Engineer, GenAI & Voice Agents

Client Industry - Technology & Digital Innovation Consulting

Contract Length - 3-4 months (running through year-end, exact end date to be confirmed)

Contract type - Freelance

You’ll join a team building a voice-based AI agent product, combining real architecture ownership with hands-on engineering. This is a hybrid role rather than a purely managerial one: you’ll shape the technical direction of the agent stack while staying directly involved in building it.

Key skills and Experience required

  • Proven track record building GenAI / agentic solutions in production
  • Hands-on experience with agent orchestration frameworks, particularly LangGraph
  • Strong software engineering and technical architecture skills, comfortable owning both design and implementation
  • Experience building voice agents / voice pipelines (e.g. Pipecat) highly valued
  • Real-time voice processing experience a strong plus
  • Familiarity with WebRTC / LiveKit a strong plus
  • Strong product sense - able to anticipate user needs and translate them into sound technical decisions rather than simply executing a predefined spec

If this role is of interest, please apply with an updated CV.
