Summary of the role:
Generative AI
ML/Data Science
Full time, permanent
3 days onsite, London
We are looking for a highly capable and innovative Data Scientist with experience in Generative AI to join our Data Science Team. You will lead the development and deployment of GenAI solutions, including LLM-based applications, prompt engineering, fine-tuning, embeddings, and retrieval-augmented generation (RAG) for enterprise use cases.
As part of your duties, you will be responsible for:
- Design and build Generative AI solutions using Large Language Models (LLMs) for business problems across domains like customer service, document automation, summarization, and knowledge retrieval.
- Fine-tune or adapt foundation models using domain-specific data.
- Implement RAG pipelines, embedding models, vector databases (e.g., FAISS, Pinecone, ChromaDB).
- Collaborate with data engineers, MLOps, and product teams to build end-to-end AI applications and APIs.
- Develop custom prompts and prompt chains using tools like LangChain, LlamaIndex, PromptFlow, or custom frameworks.
- Evaluate model performance, mitigate bias, and optimize accuracy, latency, and cost.
- Stay up to date with the latest trends in LLMs, transformers, and GenAI architecture.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Qualifications and experience we consider to be essential for the role:
- 5+ years of experience in Data Science / ML, with 1+ year hands-on in LLMs / GenAI projects.
- Strong Python programming skills, especially in libraries such as Transformers, LangChain, scikit-learn, PyTorch, or TensorFlow.
- Experience with OpenAI (GPT-4), Claude, Mistral, LLaMA, or similar models.
- Knowledge of vector search, embedding models (e.g., BERT, Sentence Transformers), and semantic search techniques.
- Ability to build scalable AI workflows and deploy them via APIs or web apps (e.g., FastAPI, Streamlit, Flask).
- Familiarity with cloud platforms (AWS/GCP/Azure) and MLOps best practices.
- Excellent communication skills with the ability to translate technical solutions into business impact.
