This is a highly hands-on role where you'll work across LLM orchestration, prompt and agent design, model integration, evaluation and voice AI.

• Experience integrating and optimising LLMs for production environments, balancing latency, cost and accuracy
• Experience building or improving AI evaluation and benchmarking frameworks
• Strong software engineering background with the ability to turn ambiguous product problems into robust technical solutions
• Comfortable working across experimentation and production delivery
• Strong communication skills, with the ability to explain complex AI concepts to both technical and non-technical audiences
• Experience mentoring engineers and contributing to technical direction and architecture decisions

Nice to Have:

• 5+ years' software engineering experience, including 2+ years working directly with LLMs/NLP in production
• Experience with LangChain, LlamaIndex or similar LLM orchestration frameworks
• Experience designing and implementing RAG architectures
• Experience with voice AI, ASR/TTS or multimodal systems
• Understanding of AI compliance considerations, including GDPR
• Experience working within a startup or fast-paced commercial R&D environment
• PhD or equivalent research experience

If you're an experienced AI Engineer who wants to work on genuinely production-focused AI, autonomous agents and voice technology, this could be a great opportunity to have a real impact as the platform scales.
