Salary: £24,000 - 59,000 per year
Requirements
- We seek a highly skilled and experienced Senior Architect/Consultant with deep understanding of Generative AI, Agentic AI, LLMs, RAG, machine learning, and modern interoperability standards such as MCP.
- We expect proven experience architecting and implementing innovative, enterprise-scale solutions.
- We require in-depth knowledge of modern Generative AI techniques and foundation models, including transformer-based LLMs, diffusion models, multimodal models, GANs, and VAEs.
- We look for hands-on experience with advanced prompt engineering, structured outputs, function/tool calling, and orchestration frameworks such as LangChain, LangGraph, LlamaIndex, and Semantic Kernel.
- We require exposure to both API-based and open-source LLM solution design.
- We seek deep expertise in designing autonomous and multi-agent systems, including agentic design patterns and agent frameworks.
- We require strong working knowledge of the Model Context Protocol and related interoperability standards.
- We look for experience extending agent capabilities through modular, reusable skills, custom tools, connectors, and standards.
- We require expertise in RAG and knowledge-grounded systems, including chunking, embeddings, vector databases, hybrid search, reranking, and retrieval evaluation.
- We expect experience operationalizing LLM and agentic systems at scale, including evaluation, observability, guardrails, red-teaming, and continuous optimization.
- We require a strong understanding of machine learning principles, algorithms, frameworks, model design, and training pipelines.
- We seek proficiency in Python, TensorFlow, PyTorch, or similar tools, along with modern LLM and agent frameworks.
- We value experience with cloud AI platforms, vector databases, Docker, Kubernetes, and distributed computing.
- We require the ability to design end-to-end Generative and Agentic AI architectures.
- We value familiarity with the relevant industry domain, data engineering practices, and AI governance, security, and responsible AI considerations.
