  • Improving real-time performance and reducing latency
  • Designing lightweight orchestration (simple, deterministic flows over complex prompt chains)
  • Integrating customer/internal data using RAG approaches
  • Optimising cost, reliability, and system efficiency
  • Building and maintaining API/SDK-based voice pipelines
  • Supporting secure handling of sensitive/PII data

What we're looking for:

  • Strong experience building voice AI or real-time speech systems
  • Hands-on experience with speech-to-text and text-to-speech APIs
  • Proven ability to deliver production-grade AI systems
  • Good understanding of latency and performance optimisation
  • Experience with RAG and data-driven AI architectures
  • Strong API integration skills and practical engineering mindset
  • Comfortable working with sensitive data in production contexts
