NCS; Singapore; On-site; SGD 180,000 - 260,000; Full time

Job summary

NCS, a leading AI Tech Services company, seeks a GenAI Platform Architect to join the AI Centre of Excellence in Singapore. You will define the target architecture, guardrails, and governance for the GenAI platform, guiding engineers to scalable, production-ready solutions.

The role spans architecture across applications, infrastructure, and security, requiring collaboration with security, data, and application teams to deliver a robust, enterprise-grade GenAI platform.

Qualifications

• 8+ years in software, platform, or AI / data engineering roles, with a clear progression toward architecture.

• Design multi-tenant platform capabilities that are safely and efficiently consumed by multiple AI projects.
• Establish architectural standards, design patterns, and non-functional requirements (security, isolation, scalability, cost, observability).
• Review and guide technical designs produced by Platform AI Engineers; act as escalation point for complex platform decisions.
• Partner with the Engagement Solution Architect to convert recurring AI project needs into platform roadmap items.
• Balance innovation with operability — make pragmatic trade-offs between ideal architecture and delivery reality.
