Backed by decades of expertise and driven by a culture of continuous learning and innovation, Singtel offers the scale, opportunities and support to help you grow your career while making a difference where it matters most.

How You will Make An Impact

  • Develop and recommend the Network Data & Knowledge architecture and contribute to the roadmap: Develop solution architecture for UDA, data processing, semantic/knowledge services and reusable data products within approved ACE, Autonomous Network and enterprise architecture principles; provide technical recommendations for roadmap evolution.
  • Engineer trusted data ingestion and processing: Design and scale real-time and batch ingestion from NRI, OSS/NMS, probes, telemetry, configuration and operational systems; standardise, transform and enrich data for downstream use.
  • Develop and maintain canonical network data models and semantics: Develop and maintain canonical models, ontology, taxonomies and semantic relationships across resource, service, customer-impact and operational domains within approved architecture and governance standards, aligned where applicable to TM Forum information models and standards.
  • Provide technical leadership for the Network Knowledge Plane: Lead technical design and engineering of graph and semantic capabilities that connect inventory, topology, services, events, incidents, performance, changes and operational knowledge into a reusable knowledge foundation within the approved architecture.
  • Design and deliver reusable network data and knowledge products: Design and deliver reusable data products and knowledge APIs in accordance with agreed ownership, contracts, quality measures, access controls and SLOs for AI, automation, assurance, analytics and application consumers.
  • Establish data governance and trust: Implement metadata, catalogue, lineage, provenance, data-quality controls, retention and access governance so data and knowledge are traceable, discoverable and fit for production use.
  • Enable AI and Autonomous Network use cases: Provide trusted context, retrieval and knowledge services for NAN, service assurance and agentic operations while keeping decision logic and autonomous action ownership with the relevant ACE capability teams.
  • Support platform engineering, performance and cost efficiency: Develop and apply approved technology patterns for scalable data, search, analytics and graph platforms; optimise availability, performance, resilience, security and total cost of ownership within established platform standards.
  • Apply DataOps and engineering excellence: Apply automated testing, CI/CD, schema/data-contract validation, infrastructure/platform automation and controlled release practices in collaboration with PRE and EPE.
  • Support product and stakeholder alignment: Provide technical input to roadmap prioritisation with network domains and ACE teams; translate approved priorities and use-case needs into reusable engineering capabilities and help prevent duplicated point solutions.
  • Support production readiness and service quality: Assess and recommend production readiness against agreed criteria and support achievement of application/platform service quality and data SLOs, working with PRE on observability, incident/problem management, resilience and operational acceptance.
  • Contribute technical input to strategy, investment and capability development: Provide technical input to AOP, business cases, procurement/vendor evaluation, workforce capability building and technology innovation for the Network Data & Knowledge domain.

Skills for Success

  • Bachelor's Degree in Computer Science, Computer Engineering, Data Engineering, Information Systems or a relevant discipline

  • More than 10 years of relevant experience in telecommunications, data/platform engineering or large-scale software/data systems, with proven technical leadership and production delivery experience.

  • Strong telecommunications-domain knowledge with experience in network inventory, topology, OSS/NMS, telemetry and service/resource data.

  • Strong data architecture and engineering experience across streaming and batch ingestion, data modelling, data contracts, lakehouse/data-platform patterns and distributed systems.

  • Hands-on understanding of search, analytical and graph technologies (e.g., Elasticsearch/OpenSearch, ClickHouse, Neo4j or equivalent) and modern lakehouse technologies (e.g., Apache Iceberg, Databricks, HPE Data Fabric or equivalent).

  • Experience in ontology, semantic modelling, knowledge graphs and metadata/catalogue/lineage capabilities.

  • Strong understanding of API/data-product design, data governance, security, quality, provenance and SLO-based service management.

  • Strong cloud-native and container-platform knowledge, including Kubernetes/OpenShift, CI/CD/DataOps and infrastructure/platform automation.

  • Experience translating AI/analytics/automation use cases into reusable data and context capabilities, including RAG/agent context patterns where applicable.

  • Working knowledge of TM Forum ODA/Open APIs and information models, or equivalent telecom standards.

  • Strong technical leadership and ability to influence across teams without relying solely on hierarchy.

  • Strong stakeholder management, facilitation and negotiation skills across engineering, operations, architecture, AI and business teams.

  • Strategic and systems thinking with strong analytical and problem-solving capability.

  • Strong communication and presentation skills, including the ability to explain complex data/knowledge concepts to senior stakeholders.

  • Product mindset, ownership and commitment to developing engineering capability and reusable solutions.

  • Network knowledge plane, ontology/semantic modelling, data-product management, Autonomous Network architecture and responsible use of AI context/data.
