Join the Bank of China’s IT team as an Systems Administration Engineer. This is a mid-level technical role for an experienced systems administrator who wants genuine, hands-on ownership of the infrastructure that keeps the business running - not a junior support position, and not a people management role.

This is a broad infrastructure role covering Windows and Red Hat Linux servers, VMware virtualisation, enterprise storage, backup and recovery, and database platforms. You'll maintain a secure, stable and resilient environment while leading infrastructure upgrades, operational improvements and production incident response.

This is a full-time, in office role, with after-hours support required from time to time. You will be remunerated for this in overtime (OT) pay or time in lieu.

- Take full operational ownership of Windows Server 2016+ and Red Hat Linux systems in a production environment, including day-to-day administration and support.
- Manage and maintain enterprise servers, storage, hardware and VMware virtual infrastructure, ensuring availability, stability, performance and capacity.
- Lead server installation, configuration, build, rebuild, upgrade, migration, patching and decommissioning in line with company standards and change procedures.
- Administer SQL Server and MySQL databases, including configuration, parameter management, data/log/temp file management, space monitoring, backup verification and troubleshooting.
- Administer VMware environments end-to-end, including VM provisioning, configuration, resource allocation, performance monitoring, capacity planning, snapshot management, migration and troubleshooting.
- Perform daily system monitoring, health checks, alert review, backup verification,



scheduled job checks and operational housekeeping to maintain infrastructure availability and integrity.
- Own backup, recovery, restoration and disaster recovery operations, including backup monitoring, restore testing and participation in DR exercises.
- Plan and execute regular OS patching, software upgrades and firmware updates, including implementation, validation and post-change checks.
- Diagnose and resolve hardware, operating system, VMware, storage and database infrastructure incidents, including root-cause investigation and remediation.
- Lead production incident response, planned maintenance, system changes and infrastructure improvement initiatives, including after-hours support when required.
- Monitor system performance, resource utilisation, storage capacity and infrastructure health, proactively identifying and addressing potential issues.
- Maintain system configuration records, technical documentation, operational procedures, recovery procedures and troubleshooting guides.
- Partner with application, network, vendor and wider technology teams to resolve production issues and deliver infrastructure projects and operational changes.

What you'll bring

- A bachelor's degree in Information Technology, Computer Science or a related discipline.




- At least 3–5 years' experience in systems administration or infrastructure support, with demonstrated ownership of production environments.
- Strong hands-on experience with Windows Server 2016+, Red Hat Linux and VMware virtual infrastructure.
- Proven experience managing backup and recovery operations, including daily monitoring, health checks, alert review, backup verification and scheduled job checks.
- Working professional proficiency in both Mandarin and English, written and spoken. Native-level proficiency is preferred, as Mandarin may be used internally and with clients or stakeholders.
- Strong troubleshooting, analytical, communication and documentation skills, with the ability to work independently and manage competing priorities.
- Australian citizenship or permanent residency.
- Knowledge of SQL Server and/or Oracle database administration is preferred but not essential.

What's on offer

- A technically broad role with genuine, hands-on ownership of enterprise infrastructure
- A clear technical career path: strong contribution & performance (and depending on the bank's requirements), the next step is typically a Senior Systems Administration Engineer or Senior Manager role
- After 2 years with Bank of China, access to internal vacancies in other teams, such as information security roles as these functions develop - current employees are always considered ahead of external candidates
- Collaborative banking technology environment
- Competitive salary, plus superannuation and allowances
- Staff benefits include meal allowance from commencement, plus additional benefits after Year 1 (commute, health and mobile allowances)
