About the Role

Our client is looking for a Senior AI & Machine Learning Engineer to lead the design, architecture, and deployment of intelligent systems that power personalised learning experiences at scale.

You will drive AI/ML innovation across LLMs, Agentic AI, NLP, recommendation systems, and adaptive learning algorithms. Working closely with product, engineering, and business stakeholders, you will shape technical direction, build reliable production-grade AI solutions, and mentor junior engineers.

This role is ideal for an experienced AI/ML engineer who enjoys solving complex technical challenges and applying advanced AI technologies to real-world educational applications.

Key Responsibilities

• Lead the design, development, and deployment of scalable, production-grade AI/ML models and systems.
• Architect end-to-end AI/ML pipelines covering data ingestion, feature engineering, model training, evaluation, deployment, and monitoring (MLOps).
• Research and experiment with LLMs, Agentic AI, NLP, recommendation systems, and adaptive learning algorithms.
• Develop and optimise LLM/SLM applications, including fine-tuning, RAG pipelines, and intelligent AI agents.
• Design and implement knowledge graphs, graph databases, and domain-specific knowledge structures to support intelligent learning systems.
• Collaborate with product, engineering, and business teams to translate user needs into measurable AI-powered solutions.
• Mentor junior AI/ML engineers and establish best practices for code quality, testing, reproducibility, and responsible AI.
• Monitor and optimise deployed models to ensure performance, reliability, scalability, and continuous improvement.
• Evaluate emerging AI technologies, tools, and frameworks to enhance the platform's capabilities.
• Contribute to technical roadmaps, architectural decisions, and the long-term AI strategy.

Requirements

• Bachelor's or Master's degree in Computer Science, Data Science, Artificial Intelligence, or a related field.
• 5+ years of hands-on experience in AI/ML systems or data engineering, with a proven track record of bringing AI/ML products into production.
• Strong proficiency in Python and experience with ML frameworks such as PyTorch, TensorFlow, and Hugging Face.
• Proven experience fine-tuning and evaluating LLMs/SLMs using domain-specific data, including RAG, prompt engineering, and model benchmarking.
• Strong experience with Agentic AI frameworks and patterns, including multi-agent orchestration, tool use, planning, and expert routing.
• Hands-on experience with knowledge graphs and graph databases, including ontology modelling and schema design.
• Experience with multimodal AI, particularly speech processing (ASR, prosody) and/or computer vision (OCR, handwriting recognition, diagram understanding), is highly desirable.
• Demonstrated ability to mentor engineers and lead technical initiatives from concept to delivery.
• Strong problem-solving, communication, and cross-functional collaboration skills.
• Genuine interest in education and applying AI to improve learning outcomes
