• →Develop and review Functional Design Specifications (FDS), Software Design Specifications (SDS), and control system functional narratives
• →Resolve conflicts between SOO, flowcharts, Cause & Effect matrices, and software implementation across all operating modes
• →Translate electrical design intent into executable ACMS, PLC, and SCADA control strategies
• →Perform detailed reviews of control logic, software flowcharts, automation narratives, and system architectures
• →Conduct technical assessments of power system resilience, redundancy, and operational risk
• →Support FMEA and reliability assessments while evaluating transient conditions, restoration sequences, and failure scenarios
• →Develop and maintain FAT, SAT, IST, and commissioning test procedures for power system automation and control systems
• →Validate automation logic and operational scenarios through simulation, testing, and commissioning activities prior to deployment
• →Support value engineering efforts to optimise cost and performance of solutions
• →Review commissioning results and support issue resolution
• →Contribute to the development and improvement of engineering standards, tools, and processes
• →Support Business Development teams with technical input for proposals and bids as required
