About the role

Key responsibilities & impact

Define target-state and reference architectures for APAC network services across data centre, campus, branch, WAN/SD-WAN, Internet gateways, cloud connectivity, wireless, remote access, network security, load balancing, and core network services.
Produce and govern high-level and low-level designs, engineering standards, approved technology patterns, configuration baselines, and lifecycle roadmaps.
Lead design reviews and provide technical assurance for strategic projects, major changes, new site onboarding, technology refreshes, migrations, and service introductions.
Define network SLIs, SLOs, error budgets, reliability KPIs, and service-health measures.
Architect end-to-end telemetry, dashboards, alerting, dependency visibility, baseline performance, and early-warning thresholds.
Own technical reliability reporting and prioritise engineering improvements using service-performance, incident, capacity, and availability evidence.
Design and develop automation for provisioning, configuration validation, compliance checks, inventory, software lifecycle, change checks, backup, recovery, and operational reporting.
Build reusable automation and Infrastructure-as-Code patterns using Python, Ansible, APIs, Git-based workflows, and orchestration platforms.
Engineer closed-loop or human-approved auto-remediation with security controls, auditability, rollback, and exception handling.
Perform reliability and failure-mode analysis; design and validate high-availability, disaster-recovery, failover, redundancy, traffic-engineering, and service-continuity patterns.
Lead capacity planning and optimise routing, switching, wireless, security-policy enforcement, application delivery, and network performance.
Act as the L3 architecture and engineering escalation point for complex, recurring, or cross-domain network reliability issues.
Lead root-cause analysis and blameless post-incident reviews, converting findings into durable improvements.
Partner with Network Operations, Regional NOC, Security, Infrastructure, Application, Cloud, and vendor teams to resolve dependencies and corrective actions.
Embed security-by-design, least privilege, segmentation, secure management access, configuration compliance, logging, and resilience controls.
Support technical risk assessments, audit responses, exception reviews, remediation plans, and lifecycle governance.
Mentor network engineers and SRE practitioners; define playbooks, templates, checklists, test plans, and operational acceptance criteria.
Facilitate architecture forums, technical reviews, proof-of-concepts, and knowledge-sharing sessions; engage vendors and stakeholders on solutions and roadmaps.

Requirements

What you’ll need

Bachelor’s degree in Computer Science, Information Technology, Engineering, Telecommunications, or a related discipline.
Minimum 8–12 years of experience in network architecture, network engineering, infrastructure/platform engineering, Site Reliability Engineering, or network operations, including substantial experience in complex enterprise environments.
Demonstrable experience designing resilient data centre, campus, branch, WAN/SD-WAN, Internet, cloud connectivity, wireless, and network-security solutions.
Strong knowledge of routing and switching, BGP, OSPF, QoS, multicast, high availability, network segmentation, VPN, DNS/DHCP/IPAM, load balancing, and network access control.
Hands-on automation experience using Python, Ansible, REST APIs, Git, data formats such as JSON/YAML, and Infrastructure-as-Code or orchestration practices.
Strong experience with observability, telemetry, SNMP, syslog, flow analytics, synthetic monitoring, dashboards, alerting, SLIs/SLOs, error budgets, and capacity engineering.
Experience with enterprise network and security technologies such as Cisco, Palo Alto Networks, Fortinet, F5, Meraki, Zscaler, and Cisco ISE, or equivalent platforms.
Strong problem-management, troubleshooting, packet-analysis, RCA, post-incident review, risk assessment, and technical documentation capabilities.
Experience in banking, financial services, or another regulated environment preferred; knowledge of MAS TRM and relevant regional regulatory requirements is advantageous.
Preferred certifications include CCNP/CCIE, vendor security or cloud-networking certifications, Python/Ansible automation credentials, SRE/DevOps qualifications, and ITIL.
