Remote Senior Machine Learning Engineer

Salary: £64,000 - 104,000 per year

Requirements

• Production ML experience, with a track record of deploying ML systems that handle messy data, fail gracefully, and require monitoring
• Strong ML fundamentals, including the ability to reason about practical trade-offs, explain feature importance versus model selection, and make sound judgment calls when unexpected issues arise
• Client-facing deployment experience, having personally owned an ML deployment end-to-end and being comfortable on calls with non-technical stakeholders
• Strong programming skills in Python, including the ML and scientific Python stack such as numpy and scikit-learn
• Daily use of AI development tools such as Claude Code, Cursor, Copilot, or equivalent as a standard working mode
• Experience in forecasting, time-series, or demand-planning would be an advantage
• Familiarity with our stack: Python, scikit-learn, MLflow, Docker, and GCP would be an advantage
• Experience working in a small team where ownership is broad and context switching is normal would be an advantage

Responsibilities

• Own client launches end-to-end, including validating data, selecting models, running UAT, going live, and monitoring performance afterwards
• Join client calls, build relationships, and understand what matters on the ground for our customers
• Work closely with our industry experts to understand client businesses and the realities of frontline operations
• Help scale our production forecasting system from a handful of clients to hundreds
• Deliver practical machine learning solutions with a focus on business outcomes, not just model accuracy
