Senior Data Scientist

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.
