Senior Data Scientist position at Hyre AI Limited in London, UK. Salary: £75,000 - £95,000 per year. Requirements: Strong experience shipping applied ML into production (not just experimentation). Strong Python ability to write maintainable, tested code. Strong SQL and comfort working directly with messy, high-volume data. Solid modelling judgement including calibration, leakage, bias, thresholding, and cost trade-offs. Experience building decisioning systems where reliability, latency, and explainability matter. Experience in fraud/scams, payments, risk, or trust sectors preferred.
