Lead AI / ML Engineer

We are seeking a versatile and highly skilled Lead AI/ML Engineer with deep expertise in Generative AI (GenAI) and Large Language Models (LLMs). This role requires a leader who can take full ownership of the AI lifecycle from initial architectural design to final production execution. You will lead the development of scalable AI-powered applications, demonstrating exceptional execution skills and the ability to deliver high-performance results under pressure in demanding production environments.

The candidate will have responsibilities across the following functions:

Machine Learning and LLM Capability:

• End-to-End ML Engineering: Build and manage comprehensive ML pipelines, including data ingestion, preprocessing, training, and evaluation using frameworks like PyTorch, TensorFlow, and Scikit-learn.
• Advanced LLM Systems: Design and implement sophisticated LLM-based applications such as autonomous agents, chatbots, and complex automation tools.
• Generative AI Specialisation: Architect and optimise Retrieval-Augmented Generation (RAG) pipelines using vector databases like FAISS, Pinecone, or Weaviate.
• Model Optimisation: Fine-tune open-source and proprietary models (e. g., LLaMA, GPT) using advanced techniques like LoRA, QLoRA, or instruction tuning.
• Agentic Frameworks: Develop complex agentic workflows utilising frameworks such as LangChain or LlamaIndex.
• Prompt Engineering: Implement expert-level prompt engineering, tool/function calling, and structured output generation.

Project Ownership and Execution:

• Full Lifecycle Ownership: Take complete accountability for the full ML and GenAI lifecycle, spanning data processing, model development, monitoring, and optimisation.
• Architectural Leadership: Drive strategic architectural decisions for AI platforms, ensuring they are modular, scalable, and maintainable.
• Execution Excellence: Write clean, high-performance Python code following strict OOP principles and manage CI/CD pipelines for seamless project execution.
• Leadership and Mentoring: Act as a key technical leader, managing stakeholders and mentoring team members to ensure all project milestones are met with quality.
• System Integrity: Manage model and prompt versioning, experiment tracking, and comprehensive documentation for all pipelines and workflows.

Performance Under Pressure:

• Production Reliability: Ensure all AI systems maintain extreme scalability and performance under heavy production workloads, including both batch and real-time processing.
• High-Pressure Optimisation: Rapidly optimise inference latency and system costs for ML and LLM systems to meet urgent business and technical requirements.
• Proactive Problem Solving: Apply strong analytical thinking to address complex challenges such as system drift, hallucinations, and latency in fast-paced environments.
• Robust Guardrails: Implement and manage strict evaluation frameworks and feedback loops to maintain system quality under stress.

Requirements:

• Bachelor's or Master's degree in Computer Science, AI, ML, or a related field.
• Proven expertise in Python, system design, and scalable AI/ML architecture.
• Deep knowledge of NLP, Computer Vision, and Deep Learning models.
• Hands-on experience with Docker, Kubernetes, MLOps, and major cloud platforms (AWS, GCP, or Azure).
