AI Engineer, Manager - Technology Consulting

About the role

EY DnA is the data and advanced analytics capability within EY Asia-Pacific, with over 500 specialist employees working across multiple industry sectors. We implement information-driven strategies, data platforms and advanced data analytics solution systems that help grow, optimize and protect client organizations. We go beyond strategy and provide end to end design, build and implementation of real-life data environments and have some of the best architects, project managers, business analysts, data scientists, big data engineers, developers and consultants in the region. We seek a AI Engineer Manager to lead the design and delivery of advanced AI solutions for clients in a consulting environment. This role is hands-on and client-facing, focused on building specialized AI systems (e.g., custom LLM-powered applications, semantic search engines, knowledge graph platforms) and ensuring successful implementation across multi-industry use cases. As a technical leader, you will bridge cutting-edge AI engineering with business needs, mentor junior engineers, and drive delivery excellence in a fast-paced forward-deployed practice. The scope spans end-to-end solution development from architecture to deployment with an emphasis on LLM fine-tuning, AI infrastructure optimization, and quality outcomes for clients. Your key responsibilities AI Solution Design & Development: Architect and build specialized AI systems tailored to client requirements, including custom NLP/LLM solutions, computer vision or data science pipelines, and retrieval-augmented generation (RAG) workflows for knowledge-intensive applications. Support the production of scalable and optimised AI or machine learning (ML) models. Focus on building algorithms for the extraction, transformation and loading of large volumes of real-time, unstructured data to deploy AI or ML solutions from theoretical data science models. Run experiments to test the performance of deployed models, and identifies and resolves bugs that arise in the process. LLM Customization & Fine-Tuning: Fine-tune and adapt large language models to client-specific domains and tasks, leveraging open-weight models (e.g. Mistral, Llama2, Qwen) or proprietary APIs as needed. Optimize prompt designs and training workflows to maximize model performance while ensuring responsible AI usage. Work with the relevant software platforms in which the models are deployed. Semantic Search & Knowledge Integration: Implement semantic search solutions and vector database integrations (e.g. FAISS, Pinecone) to enable intelligent retrieval for AI applications. Develop knowledge graphs, ontologies, and semantic layers to enrich AI systems with domain context and support reasoning. Infrastructure & Performance Optimization: Manage and optimize GPU/accelerator infrastructure (on cloud platforms like AWS, Azure, GCP or on-prem NVIDIA clusters) to support high-performance model training and inference. Drive token efficiency, latency reduction, and cost optimization in AI pipelines (through techniques like model quantization, batching, and caching). Client Project Delivery: Lead day-to-day project execution for AI engagements across multiple industries (e.g. finance, healthcare, manufacturing, public sector). Collaborate with client stakeholders to gather requirements and define technical solutions. Ensure on-time delivery of high-quality results that meet business objectives. Technical Leadership & Collaboration: Provide hands-on technical leadership to a cross-functional delivery team (data engineers, ML engineers, developers). Perform code reviews, troubleshoot complex issues, and enforce best practices in software engineering, MLOps, and DevSecOps. Coordinate with data scientists, cloud architects, and industry SMEs to integrate AI solutions within broader client architectures. Work in a team setting and apply knowledge in statistics, scripting and programming languages required by the firm. Quality Assurance & Governance: Implement robust testing, validation, and monitoring for AI solutions (model performance, data quality, bias/fairness checks). Run experiments to test the performance of deployed models and identifies and resolves bugs that arise in the process. Ensure compliance with data privacy/security and Responsible AI guidelines throughout solution design and deployment. Proactively address technical risks and maintain documentation and standards for reproducibility. To qualify for the role, you must h
