About the opportunity

We’re looking for a proactive Automation Engineer to join our Site Engineering team at our Darnum site.

In this hands-on role, you’ll be responsible for supporting and improving plant automation and control systems to maximise reliability, efficiency, and performance. Working closely with operations, maintenance, and engineering teams, you’ll identify process limitations, implement improvements, and ensure our control systems are maintained, optimised, and fit for purpose.

You’ll play a key role in delivering automation projects, supporting day-to-day plant operations, and contributing to the ongoing development of our PLC and SCADA systems to ensure the site operates safely, consistently, and at scale. Key Responsibilities include:

• Identify process limitations and implement automation and control system improvements
• Maintain, optimise, and troubleshoot PLC and SCADA systems to improve plant reliability and performance
• Design, develop, and deliver automation upgrades and capital projects
• Configure and modify control systems (PLC, SCADA, HMI, industrial networks)
• Provide technical support and guidance to maintenance and operations teams to enhance fault finding and system understanding
• Work with contractors and vendors to scope and deliver automation solutions in line with site standards

About you

We’re seeking a capable and motivated professional with a strong foundation in automation and control systems, gained through either formal engineering study or hands-on experience as a qualified tradesperson working with automated plant and machinery.

You’ll bring practical experience from a similar FMCG or manufacturing environment, where uptime, safety, and reliability are critical. Most importantly, you’ll have proven exposure to automation systems and a genuine interest in how processes are controlled, optimised, and improved.

You can demonstrate:

• Hands-on experience working with industrial automation systems in a live production environment (PLC, SCADA, HMI, instrumentation)
• Strong troubleshooting and fault-finding capability across automated equipment, control systems, and plant processes
• Exposure to control system platforms such as Allen Bradley, Siemens, or similar, and SCADA systems (e.g. Citect, FactoryTalk, Wonderware)
• Experience working on or supporting automation projects, system upgrades, or continuous improvement initiatives
• A proactive mindset with a focus on improving plant performance, reliability, and efficiency
• The ability to collaborate effectively across maintenance, operations, and engineering teams, and communicate technical concepts clearly

We value people who are passionate, ambitious, and keen to grow, whether you’re ready to step up or looking to deepen your expertise.
