We are currently working with a leading hedge fund who are looking to hire an experienced AI/ML Engineer to join their growing technology team

.

This is an opportunity to work on some interesting AI/ML projects, with a particular focus on Generative AI, large language models and multi-agent systems.

You'll be involved in building and deploying AI solutions from the ground up, working with open-source models and developing intelligent systems that can integrate with internal data, applications and business workflows. The focus is on creating secure, scalable solutions that can be deployed within a private environment.

The Role

• Design, develop and deploy AI/ML solutions, with a particular focus on LLMs and Generative AI.
• Work with open-source foundation models such as Llama, Mistral, Qwen, DeepSeek and similar technologies.
• Build and improve RAG pipelines, embedding models, vector databases and semantic search capabilities.
• Develop AI agents and multi-agent systems to support automated task execution and complex workflows.
• Work with agent frameworks such as LangGraph, LangChain, LlamaIndex, AutoGen or similar.
• Fine-tune, evaluate and optimise models for different use cases.
• Improve model performance and inference across GPU infrastructure.
• Build monitoring, evaluation and security processes to support reliable production deployments.
