Data Architect, People Team

Why this role matters If you enjoy designing, implementing, and sustaining data systems that turn data from multiple sources into something people can trust, use, and build on – this role is for you. This role sits within Changi Airport Group’s (CAG) human resource function and our mission is to attract and retain talents, build sustained capabilities and create an inspiring workplace.

This role balances strategic vision with hands-on execution. You’ll define the long-term data architecture roadmap aligned to our Digital Employee Experience (DEX) vision, while also rolling up your sleeves to solve complex integration challenges, improve data quality at the source, and ensure our HR technology ecosystem is scalable, secure, and future-proof. You’ll also lead a small specialist team and work closely with HR, IT, and business stakeholders to deliver reliable, accessible people data and data services for our internal customers .

• Establish and enforce robust data management and governance practices across all People systems
• Put in place clear quality checks, validation rules, reconciliation processes, and monitoring controls so that data is clean, accurate, and consistent throughout the data pipeline.
• Work with Data Owners to define standards (e.g. employee IDs, job functions, employment information)
• Educate stakeholders to ensure privacy, security, and compliance are baked in – not added later
• Partner with Data Owners and CAG’s Enterprise Data Science & Management Center of Excellence to define and uphold standard data definitions and taxonomies (e.g. consistent usage of employee IDs, job codes, organisational hierarchies across systems).
• Drive change management by educating stakeholders on new data tools and processes, promoting data literacy within the People Team, and ensuring organisation-wide buy-in for data initiatives.
• Provide data & data services to enable reporting, analytics, and AI
• Ensure high-quality data is ready for dashboards, workforce insights, and decision-making
• Provide & manage the data pipelines, models, and connections needed for chat-enabled data analytics & queries, transactions, and future AI agents
• Enable self-service analytics by curating clean, standardised datasets and establishing semantic layers (data marts or models) for tools like Power BI and Microsoft Fabric.
• Grow our People data capability
• Lead and mentor your People Data Architecture team in developing data pipelines, integration solutions, and analytics capabilities.
