ResponsibilitiesDesign, fine-tune, and hyper-optimise LLMs – adapt state-of-the-art models (e.g., GPT-4o, Llama 3, Mistral) with LoRA / QLoRA, PEFT, DeepSpeed, and targeted hyper-parameter tuning.
Build production-grade RAG pipelines – integrate vector stores (FAISS, Pinecone, Qdrant) with streaming market data to fuel real-time signal generation.
Deploy low-latency inference on MCP – manage and autoscale GPU endpoints with vLLM.
Lead frontier research spikes – benchmark and evaluate emerging stacks (LangChain Agents, LlamaIndex, vLLM).
Collaborate across departments to discover and prioritise business bottlenecks where AI and automation can deliver measurable impact.
Drive solutions from prototype to production while ensuring robustness, reproducibility, and maintainability.
What you bring:
0-2 years building and shipping ML / NLP systems in trading, fintech or other data-driven domains.
Deep grounding in maths, stats and optimisation; fluent in Python + PyTorch / Hugging Face.
Hands-on with vector DBs & RAG frameworks (LangChain, LlamaIndex) and modern prompt-engineering tactics.
Proven track record fine-tuning open-source LLMs (Llama, Mixtral, Mistral).
Rigorous software-engineering habits: clean code, testing culture, secure SDLC.
