Machine Learning Engineer - Defence in Aberdeen

Our client is a specialist technology consultancy delivering high-impact engineering across defence and complex environments, supporting organisations operating in secure, mission-critical settings. The focus is on solving complex problems through advanced machine learning and AI capabilities within constrained and high-assurance environments.

This role offers the opportunity to work on cutting-edge machine learning and large language model (LLM) systems, contributing to impactful solutions where performance, reliability, and security are critical.

You will have the opportunity to:

• Design and develop machine learning and LLM-based solutions
• Work on advanced AI systems within secure and constrained environments
• Apply deep technical knowledge across ML, statistics, and optimisation
• Contribute to real-world AI applications in defence and high-assurance settings
• Collaborate with engineers and clients to solve complex challenges
• Take ownership of delivery within high-impact projects

Your Responsibilities:

• Develop and deploy machine learning models and LLM-based systems
• Apply knowledge of transformer architectures and LLM principles
• Optimise model performance, inference, and efficiency
• Evaluate model behaviour using established performance frameworks
• Contribute to solutions deployed in edge, constrained, or air-gapped environments
• Apply best practices in AI safety, explainability, and robustness
• Collaborate with engineering teams to integrate ML systems into production environments

Key Requirements:
