Salary: £90,000 - 120,000 per year Requirements: We are looking for a senior or lead-level Machine Learning Engineer with strong hands-on technical ability. We require experience in machine learning engineering, particularly time-series forecasting. We value experience building scalable ML systems and production-grade machine learning infrastructure. We are looking for experience with feature stores and MLOps in large-scale environments. We would welcome experience in forecasting, recommendation systems, or customer behaviour modelling. We are interested in candidates with exposure to generative AI and LLM-related work, although this is not a pure GenAI role. We want someone who can guide and support more junior engineers while remaining technically hands-on. We value a strong research or engineering background and the ability to contribute to technical direction. We are looking for candidates who are comfortable working in a fast-moving, high-ownership environment. Responsibilities: We build forecasting, recommendation, pricing, and AI-driven decision systems at global scale. We develop machine learning models that influence commercial decisions across a large international dataset. We work on time-series forecasting and other advanced machine learning engineering challenges. We design and maintain scalable ML systems, feature stores, and MLOps workflows. We collaborate on technical decisions and help shape the direction of our AI platform and engineering practices. We stay hands-on with implementation while also supporting and mentoring junior engineers. We contribute to systems that improve pricing, marketing, and customer experience for businesses globally. We may also contribute to selected generative AI and LLM-related initiatives where relevant. Technologies: AI Support LLM Machine Learning Marketing More: We are a high-calibre AI team operating within a larger global business, with the feel of a startup culture combined with the scale and impact of an established company.
