We are looking for a Lead HMI / SCADA Systems Designer to take ownership of the operator interface layer powering our clients next-generation rail control centres. These are contract roles that can be based in any capital city in Australia with a preference for Sydney or Melbourne.
In this role, you will bridge the gap between complex field-level trackside signaling (interlockings, point machines, axle counters) and signallers who keep the network moving safely. Leveraging the clients own bespoke software package that is similar to PcVue, you will design high-situational-awareness interfaces that ensures real-time telemetry accuracy, and directly impact the safety and efficiency of rail operations.
What You’ll Do
... Design Intuitive Operator Interfaces: Create ergonomic, high-performance HMI screens based on ISO 9241 and control room human factor standards—giving signallers clear, real-time visibility over track layouts, signal aspects, and train locations.
Integrate Mission-Critical Systems: Configure robust industrial communication protocols (OPC UA, Modbus TCP, DNP3, IEC 60870-5-104) to seamlessly link trackside PLCs, RTUs, and Railway Interlocking systems to the SCADA server.
Architect Safe Command & Control Workflows: Configure signal alarm topologies, priority levels, and dual-action confirmation workflows for safety-critical actions like manual signal overrides and route locks.
Lead Testing & Validation: Build simulation models and drive Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) to validate graphic displays and control logic against simulated field inputs.
Collaborate Across Engineering Disciplines: Work hand-in-hand with Signaling Systems Engineers and Control Room Signallers to continuously refine displays based on real-world operational feedback.
What We’re Looking For
Education: Bachelor’s degree in Electrical, Automation, Systems, or Software Engineering (or equivalent practical experience).
SCADA Expertise: 2+ years of hands-on experience designing and configuring PcVue (or equivalent platform expertise in WinCC, System Platform, or Citect).
Domain Knowledge: A solid understanding of railway signaling fundamentals—including route control, interlocking logic, track circuits/axle counters, points, and signal aspects.
Industrial Protocols: Practical experience with OPC UA, Modbus TCP, DNP3, and/or IEC 60870-5-104.
Standards Awareness: Exposure to rail safety and software standards (e.g, EN 50128, SIL safety concepts, or ISO 9241).
