Senior Data Scientist

Remote (UK / EU) | Outside IR35 | 6 months (likely extension)

A leading UK platform is hiring 2 x Data Scientists to stabilise and improve production ML models while supporting key NLP projects. This is a hands‑on applied DS role, not a generic GenAI / LLM position.

• 
  
• Forecasting (demand / volume)
  
• Propensity, churn, classification
  
• Tree‑based models & classical ML
  
• Handling imbalanced datasets
  
• Debugging, retraining & maintaining 13 production models
  

• 
  
• Transformer‑based text classification (BERT / DistilBERT / RoBERTa)
  
• Fine‑tuning classification heads
  
• Embeddings + cosine similarity search
  
• Supporting LLM‑adjacent work (not deep RAG)
  

• 
  
• Python, sklearn, XGBoost / LightGBM, HuggingFace Transformers, BERT-family models, embeddings, cloud‑based ML, CI / CD awareness.
  

• 
  
• Strong applied DS experience (forecasting + classification)
  
• Real production ownership (maintaining / debugging live models)
  
• Modern NLP experience with BERT-family models
  
• Familiarity with embeddings & similarity search
  
• Able to ramp up quickly and operate independently
  

• 
  
• Outside IR35 / B2B
  
• Remote – UK / EU time zones
  
• One‑stage technical interview (+ short follow‑up)
  
• Start ASAP (December preferred)
