AI agents are only as good as the data they can reason over. Poorly structured, stale, or inconsistently governed data is the most common reason enterprise AI products fail to deliver value — not model capability, but data readiness. The AI Data Engineer at Temasek is responsible for building the data foundations that make Temasek's agentic AI systems trustworthy, accurate, and capable of reasoning over the complex, heterogeneous data environment of a global investment institution.

This role sits at the intersection of data engineering and AI systems engineering — responsible for designing and building the data architectures, pipelines, and quality frameworks that allow AI agents to retrieve, reason over, and act on Temasek's investment data. You will work across structured investment data (portfolio positions, financial statements, market data), unstructured data (research reports, company filings, meeting notes, news), and real-time data streams — making all of it accessible, reliable, and AI-readable.Responsibilities Agent-ready data architecture

• Design and build data architectures optimised for AI agent consumption, including structured stores exposed via APIs, vector databases for semantic retrieval, graph databases for relationship reasoning, and hybrid retrieval systems combining keyword, semantic, and structured queries.
• Own the data layer for RAG pipelines: document ingestion workflows, chunking strategies, embedding generation and refresh, metadata tagging, and vector index management across domains (e.g., company research, market intelligence, portfolio data, regulatory filings).
• Establish ontology and schema standards to ensure AI-accessible data is consistent, well-documented, and interpretable without custom parsing logic.
• Architect real-time and near-real-time data feeds (e.g., market data, news, portfolio events), defining and enforcing latency and freshness SLAs.

Enterprise data quality and governance

• Define and implement data quality standards (completeness, consistency, freshness, anomaly detection) with automated quality gates to prevent degraded data entering AI systems.
• Build end-to-end data lineage tracking across AI pipelines, enabling traceability from source to AI consumption for debugging and audit requirements.
• Partner with AI Security & Governance and enterprise data teams to ensure compliance with data classification, access control, and cross-border handling requirements (including China-related workflows).
• Design and operate data observability tooling covering pipeline health, data drift, schema changes, and SLA monitoring, giving product teams visibility into data reliability.
• Run regular da
