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.
