A fast-moving, rapidly growing commodity trading firm, and a leading market-maker in energy derivatives, is continuing to scale and is looking for an AI / LLM Engineer to help design and deploy advanced AI-driven solutions across the business. This role is suited to an engineer who enjoys working close to the business, building production-grade AI systems, and operating in a high-performance financial services environment.
 
Overview
