Job description

Senior Data Scientist (Contract) – Forecasting + Modern NLP (BERT)

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.

You’ll Work On

Applied DS (core)

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

Modern NLP (secondary but required)

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

Tech

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

What They’re Looking For

• 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

Details

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

If you have strong applied DS fundamentals plus hands‑on transformer NLP experience, feel free to apply or message me.
