An interest in Artificial Intelligence, Large Language Models (LLMs) and AI-augmented software development.
Familiarity with Git-based version control and an appreciation for testing, code reviews and software quality practices.
A proactive, can-do attitude, strong learning agility, and the resilience and ownership mindset needed to thrive in a fast-paced environment.
Excellent collaboration and communication skills, coupled with a genuine enthusiasm for learning about metals markets, commodities trading and the wider energy sector .
