About the Role

We’re partnered with a fast-growing tech startup focused on how brands and retailers use data. Their AI platform brings together data science, immersive visualisation, and large-scale machine learning to optimise product ranges, plan shopper journeys, and drive smarter commercial decisions.

They’re now looking for a Senior ML & AI Engineer to join their lean, high-impact engineering team. This is a pivotal role at the intersection of ML engineering, backend systems, and LLM integration - ideal for someone who thrives in fast-paced, hands-on environments where ML systems are core.

Responsibilities

• Design, build, and maintain scalable backend systems that power advanced ML and LLM applications.
• Develop and manage end-to-end MLOps pipelines with automation, reproducibility, and scalability at their core.
• Deploy and monitor machine learning and LLM models in production, identifying model drift and performance issues.
• Drive research and development in modern ML, AI, and LLM approaches, applying SOTA techniques in a real-world setting.
• Champion clean, maintainable, and well-documented code following best engineering practices.

What We’re Looking For

• Strong academic background in Computer Science, ML, AI, or a related field.
• Deep hands-on experience with Python and ML frameworks (PyTorch, TensorFlow, Hugging Face).
• Proven background in MLOps, including model versioning, CI/CD for ML, and production monitoring.
• Experience building robust backend systems and APIs to serve ML models at scale.
• Strong understanding of big data technologies and data orchestration tools (Airflow, DBT).
• Familiarity with LLM integration and optimisation in production environments.
• Excellent problem-solving, analytical, and communication skills.
• Experience fine-tuning LLMs (e.g. Unsloth, cloud-based methods).
