Infrastructure Support Engineers – L2 & L3

We are seeking L2 and L3 Infrastructure Support Engineers to join our projects team delivering a large-scale enterprise virtualisation transformation for a major Singapore banking client. This programme centers on VMware to Hyper-V migration, datacentre transformation, and building secure, compliant infrastructure for mission-critical workloads.

We're hiring across two levels:

L3 Senior Technical Architect / Infrastructure Engineer

Lead design, provide technical authority, and own complex workstreams end-to-end. You'll shape architecture decisions, mentor engineers, and act as final escalation for the project.

L2 Infrastructure Engineer

Execute migration and implementation activities under L3 guidance. You'll be hands-on with day-to-day delivery, troubleshooting, and operational handover while growing toward senior capability.

Key Responsibilities

• Provide technical oversight of implementation and deployment activities across enterprise virtualisation platforms. Act as the senior escalation point for complex L3 infrastructure issues throughout the project lifecycle.
• Contribute to technical governance, architectural review boards, risk assessments, and change advisory processes. Mentor and guide junior engineers, providing technical direction and supporting their professional development. Collaborate closely with project managers, vendors, customer architects, and security teams to ensure aligned delivery. Support pre-sales activities including solution scoping, effort estimation, and technical proposal contributions where required.

L2 Engineer:

• Support customer workshops and assist with technical discovery and requirements gathering. Execute infrastructure migration activities from VMware to Hyper-V under senior guidance. Carry out implementation and deployment tasks across enterprise virtualisation platforms. Investigate and resolve L2 infrastructure issues, escalating complex problems to L3 engineers with clear diagnostics.
• Contribute to technical documentation including implementation plans, migration runbooks, and operational handover documents. Support change management activities and follow established governance processes. Work collaboratively with project teams, vendors, and customer stakeholders.
