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
As an AI / LLM Engineer, you will be responsible for building, deploying, and optimising AI and large language model solutions that support trading, risk, operations, and decision-making workflows. You will work closely with engineers, traders, and senior stakeholders to translate real business problems into scalable AI systems.
This is a hands-on engineering role, with a strong focus on production deployment, cloud infrastructure, and real-world model usage rather than pure research.

- Build scalable pipelines and services across multi-cloud environments (AWS, GCP, Azure)
- Collaborate closely with engineering, data, and business teams to deliver real commercial impact
- Develop and integrate intelligent AI agents / agentic workflows that act autonomously to solve key problems across the firm
- Ensure reliability, performance, and security of AI systems in a regulated financial environment
- Continuously improve model performance, cost efficiency, and scalability
Essential Skills & Experience
- Proven experience as an AI Engineer, Machine Learning Engineer, or LLM-focused Engineer
- Hands-on experience building and deploying LLM-powered applications
- Strong multi-cloud experience across AWS, GCP, and/or Azure
- Background in financial services, ideally within trading, capital markets, commodity trading, or large enterprise banking
- Strong software engineering skills with a focus on production systems
- Comfortable working in fast-paced, high-pressure environments
- Ideally looking for practical experience building or deploying intelligent AI agents / agentic systems that automate workflows in production - whether custom‐built or via frameworks like AI‐Gentic and similar platforms

- Salary around £130,000, dependent on experience
- Competitive benefits package
- Onsite (5x week in London)
