Join a new Generative AI Innovation Lab as a Senior AI Engineer, building and deploying LLM-powered systems with a focus on tone and style alignment, RAG, and multimodal AI including audio and voice. This is a zero-to-one opportunity to shape cutting-edge AI initiatives within a small, highly skilled team. You will fine-tune large language models, design datasets, and develop evaluation frameworks. The role is hybrid, based in the UK, with a salary of £100,000 – £140,000 per annum.

• Fine-tune large language models for tone, style, and domain-specific applications.
• Design, curate, and manage high-quality datasets for fine-tuning, including annotation, versioning, and data preparation workflows.
• Build, optimise, and evaluate retrieval-augmented generation (RAG) pipelines using structured and unstructured data.
• Prototype and test text-to-speech (TTS) and speech-to-text (STT) pipelines using technologies such as ElevenLabs, OpenAI TTS, and Whisper.
• Collaborate with engineering, infrastructure, frontend, and design teams to develop innovative AI-powered tools and applications.
• Develop and own evaluation frameworks using BLEU, ROUGE, custom metrics, and human-in-the-loop feedback.
• Support experimentation with real-time generation, summarisation, personalisation, and intelligent content delivery.
