Platform AI Security Architect at ncs3 – Singapore | Jobyssey

As a Platform AI Security Architect, you will be part of the AI Center of Excellence (AI COE), a centralized platform team responsible for building, operating, and evolving enterprise-grade AI and data platforms consumed by multiple internal engineering project teams.

The AI COE operates as a platform product organization, not a project delivery or system integration team. It owns shared capabilities end-to-end, including integration services, AI enablement, developer tooling, observability, and governance. Success is measured by platform adoption, usability, reliability, and long-term value, rather than one-off delivery milestones.

What will you do?

Define and govern AI security architecture: Establish and maintain the AI platform security architecture aligned with enterprise and telco standards, reviewing and approving security designs for platform components and high-risk AI use cases.
Embed security-by-design across AI lifecycles: Apply Zero Trust and secure-by-design principles across infrastructure, integration, data, application, and AI layers, leading threat modelling and AI-specific risk assessments.
Ensure compliance and continuous risk remediation: Partner with Enterprise Architecture and Group Security to balance compliance and innovation, and guide remediation of findings from audits, penetration tests, and security assessments

The ideal candidate should possess:

8-12+ years of experience in security architecture, enterprise security, or platform security
Experience working across Agile and Waterfall delivery environments
Ability to manage multiple complex security engagements in parallel
Relevant security certifications (e.g. CISSP, CISM, CCSP, cloud security certifications) are a plus
Strong expertise in security architecture, including:
- Zero Trust architecture
- Micro-segmentation
- Identity and Access Management (IAM)
Strong Experience in AI and GenAI security, safety and threat protection
- Responsible AI
- Prompt Injection and other GenAI threats
- Guardrails and GenAI redteaming
Experience in cloud and platform security (AWS, Azure, GCP, containers, Kubernetes)
Hands-on experience with threat modelling and security-by-design practices
Knowledge of industry frameworks and standards such as NIST CSF, CIS benchmarks, ISO/IEC 27001
Familiarity with security tooling (IAM, WAF, SIEM, vulnerability scanning, SAST/DAST)
Strong stakeholder management and communication skills
