Be a Part of Something BIG!

The role reports to the Senior Director – Group Strategy, Engineering, and Innovation (GSEI) / Network Transmission.

The Senior Engineer contributes to the definition and evolution of Singtel Group’s IP Transport architecture, supporting the development of standards, roadmaps, and reference designs. The role works closely with domain architects, OpCos, and vendors to ensure architectural alignment, technical soundness, and smooth implementation across a multi-vendor environment.

The role focuses on both architectural design and practical implementation considerations, supporting the migration from legacy transport networks toward modern IP architectures, including Segment Routing (SR-MPLS / SRv6), EVPN, automation, and controller-based networking models. The role also drives the evolution of Transport Networks as an Autonomous Domain within the Group’s Autonomous Networks (AN) architecture, enabling higher levels of automation, closed-loop assurance, and domain intelligence aligned with AN maturity target.

Make an Impact by

IP Transport Architecture & Design

• Contribute to the development and continuous improvement of the Group IP Transport architecture principles and 3–5 year roadmap.
• Develop detailed high-level designs (HLD) aligned with Group reference architectures.
• Support the evolution toward Segment Routing, EVPN-based architectures, traffic engineering, and automation-enabled operational models.
• Ensure designs meet carrier-grade requirements for scalability, resiliency, security, and operational simplicity.
• Work closely with Transmission, Optical, Core, and Access teams to ensure cross-domain design alignment.

Technology Evaluation & Implementation Support

• Evaluate emerging IP technologies including SRv6 enhancements, EVPN use cases, network disaggregation, telemetry, and automation frameworks.
• Participate in proof-of-concept (PoC) activities, lab validations, and interoperability testing across multi-vendor environments.
• Produce technical evaluation reports, design recommendations, and migration strategies.
• Support standardization and documentation of best practices across OpCos.

OpCo Collaboration & Advisory

• Work with OpCos to review existing IP Transport designs and provide technical recommendations aligned to the Group future-state architecture (FSA).
• Support OpCos during architecture reviews, solution design discussions, and vendor evaluations.
• Facilitate knowledge-sharing sessions and workshops to promote engineering best practices and consistent design approaches.

Governance & Documentation

• Support architecture governance processes through structured design reviews and compliance checks.
• Maintain architecture documentation, design guidelines, and technical standards.
• Provide periodic updates on technical progress, risks, and implementation challenges.

Skills for Success

• Bachelor’s degree in Telecommunications, Computer Engineering, or a related field.
• 5-10 years of experience in IP networking, with strong exposure to service provider transport networks.
• Hands-on experience designing and implementing IP Transport solutions using IS-IS, OSPF, BGP, MPLS, EVPN, and Segment Routing.
• Experience in core and metro IP network design, migration planning, and large-scale deployment environments.
• Experience working with major telecommunications vendors in technical solution discussions.
• Strong expertise in IP Transport technologies including L2/L3VPN, traffic engineering, fast reroute (FRR), and high-availability design principles.
• Good understanding of automation concepts, controller-based networking, and network programmability (e.g., APIs, model-driven telemetry).
• Strong analytical and troubleshooting skills with the ability to translate architectural intent into implementable designs.
• Ability to work effectively in a matrix organization across multiple OpCos and cross-functional teams.
• Clear and structured communication skills, with the ability to present technical concepts to both engineering and management stakeholders.

Rewards that Go Beyond

• Flexible work arrangements
• Full suite of health and wellness benefits
• Ongoing training and development programs
• Internal mobility opportunities
