The role reports into the Senior Director – Group Strategy, Engineering, and Innovation (GSEI) / Network Services Development (NSD). It plays a pivotal role in shaping Singtel Group’s AI-driven network, Autonomous Networks (AN), OSS and CPaaS architecture strategy.

The role defines and governs the Group Network AI and AN architecture, framework, and roadmap, while guiding OpCos on AI/AN use cases and aligning OpCo roadmaps with Group strategy and AN maturity targets.

The role focuses on enabling the transition from traditional network operations to AI-enabled and autonomous operating models, spanning network, OSS and IT domains, while ensuring architectural consistency, scalability, and long-term sustainability across the Group.

Make an Impact by

Network AI / AN Strategy and Architecture

• Define the Group Network AI and Autonomous Networks (AN) architecture, framework, and roadmap aligned to Singtel28 and TM Forum AN maturity models (L3/L4).
• Develop and maintain AN reference architectures, architectural guardrails, and best practices to guide OpCo implementations.
• Work with network domain experts to align AI/AN adoption across RAN, Mobile Core, Transport, Fixed Access, OSS, and Network Operations.

OpCo Engagement and Alignment

• Partner with OpCos to identify AN use cases, assess architectural readiness, and identify gaps across network, OSS, and IT layers.
• Provide architectural advisory support to OpCos to guide roadmap definition and prioritisation toward AN maturity targets.
• Ensure alignment of OpCo AN initiatives with Group architecture and strategy

OSS Strategy & Transformation

• Provide architectural leadership and guidance on OSS transformation initiatives, including platform strategy, AI enablement, and alignment with AN L4 objectives.
• Support and align Group and OpCo OSS-related decisions, including tender evaluations, vendor assessments, and strategic direction (e.g. agentic AI on existing OSS platforms versus platform replacement).
• Work with OpCos and vendors to ensure OSS solutions support AI-driven service assurance, closed-loop automation, and future AN L4 evolution.
• Engage stakeholders during tender specifications, vendor clarification workshops, and solution evaluations to ensure alignment with Group AN architecture and roadmap.

CPaaS Architecture & Enablement

• Provide Group-level architectural guidance for CPaaS initiatives, ensuring alignment with Network architecture, and digital service exposure strategies.
• Work with OpCos to align CPaaS architectures, API exposure models, and integration patterns with Group standards.
• Support CPaaS tender specifications, vendor evaluations, and clarification workshops, ensuring scalable, secure, and future-ready solutions.

Technical Leadership and Governance

• Provide technical leadership on AI, automation, closed-loop control, intent-based operations, A2A-T, MCP and agentic AI within network environments.
• Engage vendors and partners to evaluate AI/AN, OSS, and CPaaS solution architectures, influencing product direction and roadmap alignment.
• Support architecture governance forums to drive consistency, reuse, and scalability across the Group.
• Contribute to industry engagement and standards activities related to Autonomous Networks, AI, and network automation where applicable.

Skills for Success

• Bachelor’s degree in computer science, Engineering, or a related field.
• 15+ years of experience in telecommunications with deep expertise across network, OSS, and IT architecture, including large-scale transformation initiatives in complex telco environments.
• Proven track record in defining and governing network and IT architectures, translating strategy into executable technical roadmaps across regional operating companies.
• Hands-on experience designing and governing end-to-end Network AI and Autonomous Network architectures, including telemetry ingestion, AI/ML inferencing, automation, orchestration, and closed-loop control.
• Experience integrating AI-driven capabilities across OSS, network, and IT layers, alongside hands-on work with automation and AI/ML platforms and AI-enabled OSS.
• Experience engaging and working with major telecommunications vendors across architecture and solution discussions.
• Deep expertise in telecommunications network and OSS architectures, covering RAN, Core, Transport, Service Assurance, and Network Operations domains.
• Strong technical capability in Network AI, automation frameworks, and Autonomous Networks (AN) architecture, including AI-assisted and closed-loop operational models.
• Hands-on familiarity with TM Forum AN frameworks, Open Digital Architecture (ODA), and AN maturity models (L1–L4).
• Proven ability to translate strategic intent into practical, implementable architecture designs, reference architectures, and roadmaps.
• Strong technical leadership and consultancy skills, with the ability to govern architecture, conduct design reviews, and align solutions across complex, multi-vendor environments.
