Information Technology - Lead Systems Engineer, IT Network Comms (Core DC)

Role purpose

Guided by overall objectives of operational reliability, speed, and cost efficiency, you will be responsible for the architecture, design, implementation and day-to-day operations of the SIA Group’s core Data Centre network, keeping mission-critical services highly available, performant, and secure. This engineering role requires an analytical mindset, good awareness and appreciation of operational practices, and strong expertise in automation and AI-enabled operations in order to reduce toil, improve incident response, and strengthen resilience at scale.

What you will do

1) Service Operations & Reliability

•Provide operational support for core DC networking (routing/switching, segmentation, connectivity)

•Drive Incident, Problem, Change, and Configuration MANAGEMENT to meet service targets and standards

•Serve as technical lead during major incidents, performing deep-dive troubleshooting, RCA, and driving corrective/preventive actions

•Plan and execute complex changes with risk assessment, readiness checks, back-out planning, and post-change validation

•Maintain high-quality configuration and operational documentation; continuously improve runbooks/SOPs

2) Operational Automation & AI-enabled Ops

•Design and build automation to improve BAU consistency and efficiency (e.g.,config deployment/validation, compliance, health checks, reporting)

• Use Ansible, Python, and APIs to standardize operational workflows.

• Apply AIOps/AI-assisted operations (event correlation, anomaly detection, noise reduction, and predictive alerting) to reduce MTTR

• Scale automation patterns

3) Security Operations & Zero Trust

•Operate and improve the security posture of DC network infrastructure

•Support micro-segmentation and Zero Trust-aligned controls within the datacenter network

•Proactively identify resiliency and security gaps and drive remediation through engineering changes and automation

4) Vendor & Service Delivery Management

•Collaborate with vendors and stakeholders to ensure service availability and timely issue resolution

•Track incidents/problems/tickets to ensure SLA adherence, quality updates, and timely closure

•Participate in service delivery reviews and drive actions that improve outcomes

5) Continuous Improvement & Technology Refresh (Ops-led)

•Identify operational pain points and implement improvements across process, tooling, monitoring, and automation

•Participate in POCs/lab validations to improve operability, reliability, and automation

What we are looking for

•~6+ years of hands-on network operations/engineering experience in a multi-vendor environment.

•Strong DC networking fundamentals (routing/switching, troubleshooting, complex change execution).

•Experience with operational practices: incident/problem/change management,RCA, and service reliability.

•Experience implementing process re-engineering and automation to improve processes.Strong problem-solvingskills with the ability to isolate and resolve issues in complex environments.

•Excellent team player; ability to manage conflicts to achieve common goals.

•Strong communication skills; comfortable engaging technical and non-technicalstakeholders.

Good to have

•Experience in two or more of: core DC networking, security, networkautomation.

•Working knowledge of Ansible/Python/APIs (or motivation to build thiscapability quickly).

•Familiarity with segmentation/micro-segmentation and operational securityhygiene.

•Certifications such as Cisco/F5/Palo Alto/Check Point (or equivalent).

•Awareness of AIOps/AI trends and ability to apply them pragmatically.
