Critical Infra Controls Field Engineer

Our client

Our client is a leading global technology organisation operating large-scale, mission-critical infrastructure. Its Field Engineering team supports the safe, reliable operation and continuous improvement of a data-centre portfolio.

The role

This initial 12-month contract will provide coverage within the Field Engineering team. You will act as a technical escalation point for complex controls issues, moving from field evidence to root cause and from root cause to practical, repeatable engineering improvements.

Based primarily at data-centre locations across Sydney, you will work at the intersection of controls software, networking, mechanical systems, electrical systems and critical-facility operations. The work is varied and may also involve desktop-based reviews and technical guidance for stakeholders across APAC.

Key responsibilities

• Investigate complex controls incidents using trend data, alarms, event logs, code, system evidence and field observations.
• Review controls logic, function blocks and approved Sequences of Operations to identify faults, risks and opportunities for improvement.
• Troubleshoot BMS, EPMS, PLC, SCADA, controllers, field I/O, sensors, actuators and controls networks.
• Complete code reviews and contribute to reusable templates, controls standards, test scripts and engineering playbooks.
• Support controls retrofit designs, legacy system updates and first-of-kind pilots from technical review through validation.
• Prepare clear root-cause analyses, technical reports and recommendations for engineering and operational stakeholders.
• Partner with operations, commissioning, deployment, design, cybersecurity, product teams and vendors to resolve technical issues.

Skills and experience

• Hands-on experience designing, programming, commissioning, servicing or optimising BMS, EPMS, PLC, SCADA or comparable controls systems.
• Ability to review controls code, logic or function blocks and conduct structured fault-finding and root-cause analysis.
• Experience interpreting or developing Sequences of Operations, ideally for cooling systems, pumps, air-handling units, chillers or similar mechanical equipment.
• Strong understanding of controllers, field devices, network infrastructure and industrial protocols such as BACnet or Modbus.
• Clear written and verbal communication, with the autonomy, ownership and curiosity to work through unfamiliar technical problems.
• Experience in data centres is advantageous but not essential. Candidates from building automation, industrial controls, controls commissioning, manufacturing, robotics, critical facilities or controls-focused reliability engineering backgrounds are encouraged to apply.

Benefits and additional information

• Initial 12-month contract.
• Sydney-based role, the location may vary according to operational requirements.
• Monday to Friday, generally 8.00am-4.00pm or 9.00am-5.00pm, with no regular weekend work or standard out-of-hours requirement.
• No regular travel is expected. Any occasional travel requirement would be discussed in advance.
• Exposure to complex, large-scale infrastructure and changing technical challenges across a regional environment.
