Reo Recruitment; Sydney; On-site; AUD 120,000 - 160,000; Full time

Job summary

Reo Recruitment is seeking an experienced SCADA or controls engineer to strengthen our renewable energy client's OT environment. The role involves hands-on work with Ignition, PLC/RTU systems and plant controllers, across design, commissioning and operational handover.

You will investigate problems across SCADA and controls, coordinate responses with internal teams and vendors, and help improve configuration, system recovery, documentation and testing standards for long-term support.

Qualifications

• Must have strong Ignition experience including configuration, scripting and alarms.
• Breadth across PLC/RTU, telemetry and plant-control systems.
• Experience diagnosing issues across DNP3, Modbus, OPC UA and IEC 61850.
• Ability to translate complex problems into practical engineering actions.

Responsibilities

• Take ownership of complex SCADA and controls faults across operational assets.
• Configure and enhance Ignition-based applications and interfaces.
• Investigate PLC, RTU and plant-controller behaviour across renewable sites.
• Trace telemetry and control issues across field, network and SCADA layers.
• Support communications across DNP3, Modbus, OPC UA and IEC 61850 environments.
• Improve the quality, availability and reliability of operational data.
• Contribute engineering input into new assets, upgrades and control-system designs.
• Plan and support technical testing during project and commissioning activities.
• Strengthen system backup, restoration and operational support arrangements.
• Work across operations, engineering, cyber, infrastructure and external vendors.

Job description

You will join a renewable energy business requiring an experienced SCADA & Controls Engineer to strengthen the performance, reliability and supportability of its operational technology environment. This is a hands‑on position where you will work across existing assets while also contributing to projects moving through design, commissioning and operational handover.

Your remit will cover SCADA applications, automation hardware, plant controllers, communications, telemetry and supporting data platforms. Rather than operating within one narrow technical stream, you will investigate problems across the full controls environment, determine where issues originate and coordinate the right technical response with internal teams, site personnel and specialist vendors.

The role also provides the opportunity to improve how these environments are supported longer term. You will help strengthen configuration practices, system recovery, technical documentation, testing standards and operational readiness, while contributing engineering input into upgrades, new assets and future control‑system decisions. The underlying environment includes Ignition, PLC/RTU technology and renewable plant‑control systems.

Responsibilities

• Take ownership of complex SCADA and controls faults across operational assets
• Configure and enhance Ignition‑based applications and associated interfaces
• Investigate PLC, RTU and plant‑controller behaviour across renewable sites
• Trace telemetry and control issues across field, network and SCADA layers
• Support communications across DNP3, Modbus, OPC UA and IEC 61850 environments
• Improve the quality, availability and reliability of operational data
• Contribute engineering input into new assets, upgrades and control‑system designs
• Plan and support technical testing during project and commissioning activities
• Strengthen system backup, restoration and operational support arrangements
• Work across operations, engineering, cyber, infrastructure and external vendors

Candidate Profile

You will be an experienced SCADA or controls engineer with a strong background in utilities, renewable energy or another comparable operational environment. The role requires someone who can work directly with SCADA applications, PLCs, RTUs and plant‑control systems rather than operating purely at a design or project‑management level. Practical Ignition experience is particularly important, including configuration, scripting, alarms, data integration and system administration.

Your technical breadth should extend into industrial communications and telemetry, with the ability to diagnose issues across protocols such as DNP3, Modbus, OPC UA and IEC 61850. You should also understand how plant controllers interact with wider renewable operations and be comfortable supporting commissioning, technical testing, system restoration and production changes in operational environments.

Just as importantly, you will be able to work across multiple technical groups and translate complex problems into practical actions. You will need sound engineering judgement, disciplined documentation and the confidence to coordinate vendors and technical specialists. Exposure to SEL RTAC, BESS controls, virtualised SCADA environments or mixed Windows/Linux environments would be advantageous rather than essential.

You will join a renewable energy organisation continuing to invest in the technology underpinning its operational assets. The environment will suit an engineer who enjoys solving difficult technical problems, working across multiple disciplines and leaving systems in a stronger state than they found them.

• 3–6 month contract with broad technical ownership
• Exposure across operational assets and new energy projects
