Senior AI Engineer

The AI Engineer will be a key contributor to HEINEKEN's Global GenAI Lab in Singapore, responsible for designing, developing, and deploying end-to-end AI solutions that deliver measurable business value across the organization. This role combines deep expertise in Generative AI, Machine Learning, and Software Engineering to build scalable, secure, and production-ready AI applications.

As part of a fast-moving and innovative team, you will operate with the agility of a start-up while leveraging the scale and reach of a global enterprise. You will work with cutting-edge AI technologies to solve complex business challenges and accelerate HEINEKEN's digital transformation journey through impactful GenAI solutions.

The ideal candidate is a highly adaptable engineer with a strong technical foundation, curiosity to learn new domains, and the ability to translate emerging AI capabilities into practical business outcomes. You will be expected to take ownership of solutions end-to-end, collaborate closely with business stakeholders, and contribute to the evolution of the lab's engineering, MLOps, and DevOps capabilities.

Key Responsibilities

AI Solution Development
Design, build and operate production-grade GenAI systems in Python: agents and tool use (MCP, function calling), RAG backends, document parsing pipelines, APIs and containerised services on Azure.
Define and implement evaluation and observability for everything the lab ships; make quality measurable and reportable to stakeholders.
Build end-to-end AI solutions that integrate seamlessly with existing enterprise systems and workflows.
Create functional demonstration interfaces and prototypes.

GenAI Devops and ML Ops
Manage and own cloud infrastructure
Advise the team on best practices for implementing cloud architecture for AI solutions
Collaborate with the organization to set standards on AI enabled engineering

Software Engineering & API Development
Drive engineering standards (code review, SDK packaging, documentation on Confluence/DevOps).
Build robust, scalable APIs and microservices that serve AI models in production environments.
Develop containerized applications using Docker and orchestration platforms for reliable deployment.
Create and maintain clean, well-documented code that follows best practices for enterprise software development.
Implement proper error handling, logging, and monitoring for AI applications.

Data Pipeline Engineering
Design and implement robust data pipelines for preparation, cleaning, and integration of diverse data sources.
Handle enterprise data challenges including Excel files, PowerPoint presentations, and Office 365 integrations.
Build ETL processes that ensure data quality and consistency for AI model training and inference.
Implement data processing solutions that scale efficiently with growing data volumes.
Develop data validation and monitoring systems to maintain pipeline reliability.

Enterprise Integration & Deployment
Lead technical scoping with product owners; convert ambiguous business asks into defined user stories, inputs and expected outputs; hold scope on POCs.
Integrate AI solutions with existing business systems, databases, and enterprise applications.
Navigate complex enterprise environments and work with legacy systems and data formats.
Implement security best practices and ensure compliance with enterprise governance requirements.
Manage model lifecycle including version control, A/B testing, and performance monitoring.

Research & Innovation
Track and evaluate emerging models, frameworks and tooling; run structured bake-offs and recommend what the lab adopts.
Conduct applied research to solve novel business problems using state-of-the-art AI techniques.
Evaluate and benchmark different AI models and approaches for specific use cases.
Contribute to the lab's knowledge base and share learnings across the team
