AI / LLM Engineer

Permanent | Up to £140,000 + benefits

London | 5 days on-site

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 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.

Role Responsibilities

Design, build, and deploy AI and LLM-based solutions into production environments

Work with large models, prompt engineering, orchestration, and evaluation

Integrate AI solutions into existing trading, analytics, and operational platforms

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

Package

Salary around £140,000, dependent on experience

Competitive benefits package

Onsite (5x week in London)
