Your role

• Build AI-enabled applications using generative AI, machine learning, natural language processing, document intelligence and intelligent automation.
• Develop assistants, copilots, semantic search, recommendation, classification, document-analysis and workflow-support solutions
• Build RAG pipelines using enterprise documents and data, with traceable sources and appropriate access controls
• Integrate models with web applications, APIs, databases, Microsoft 365, SharePoint, ERP, CRM and client systems
• Write clean, modular, tested and documented production code; participate in code reviews and collaborative engineering practices.
• Implement prompts, structured outputs, validation, guardrails, model routing and fallback mechanisms
• Prepare and transform structured and unstructured data for retrieval, evaluation and application development
• Evaluate accuracy, relevance, groundedness, hallucination, latency, cost, robustness and reliability
• Support secure cloud, hybrid or client-managed deployment, including logging, tracing, monitoring and incident resolution
• Apply privacy-by-design, security-by-design and responsible-AI principles throughout development
• Contribute to internal LBC solutions, reusable components, technical standards, accelerators and AI-enabled products
• Participate in client workshops, demonstrations, proposals, knowledge transfer and adoption support

The AI Engineer will design, develop, integrate and deploy AI solutions for LBC’s clients and for LBC’s own transformation into an AI-powered organisation. You will work in multidisciplinary teams with AI engineers, data scientists, software developers, architects, business analysts, consultants, designers and governance specialists. This is a hands-on engineering role for someone who can turn business requirements, models and data into reliable applications. You will contribute across the full lifecycle: discovery, solution design, development, testing, deployment, monitoring and continuous improvement.
