software-development, peer-review, testing, release, and configuration-management practices.\nDefine interfaces for equipment commands, status, position feedback, alarms, diagnostics, permissives, trips, safety signals, remote monitoring, data collection, event logging, and maintenance diagnostics.\nIntegrate assigned equipment with plant controls, supervisory systems, industrial networks, remote I/O, local and control-room operator interfaces, and approved cybersecurity architectures.\nSupport appropriate separation and interface definition among equipment controls, plant controls, plant protection systems, and other safety functions.\nReview supplier designs, calculations, drawings, software, test procedures, and technical submittals for compliance with project requirements.\nSupport supplier technical evaluations, procurement specifications, design reviews, inspections, test witnessing, FAT, SAT, load testing, installation, commissioning, startup, and turnover.\nDevelop or review acceptance criteria, test plans, test procedures, test reports, and resolution documentation for design changes, nonconformances, and corrective actions.\nSupport troubleshooting, operability evaluations, root-cause analysis, corrective-action implementation, reliability improvement, and lifecycle management of assigned systems\nMaintain traceability among control-system requirements, design outputs, interfaces, software implementation, and verification activities throughout the system development lifecycle.\nEvaluate and implement control-system design changes in accordance with applicable engineering change, configuration-management, and design-control processes.\nCoordinate control-system design interfaces with process, mechanical, electrical, nuclear, operations, cybersecurity, and other applicable disciplines to ensure integrated system performance and resolve interface issues.\nPerform or support design verification and technical reviews to confirm that control-system designs satisfy applicable requirements, interfaces, design criteria, and engineering standards.\nMentor junior engineers and contribute to technical standards, reusable designs, control libraries, test methods, and lessons learned\nControl Software Development and Implementation\nDevelop, configure, review, test, and implement control software for programmable logic controllers and other industrial control platforms.\nKnowledge of developing control logic using IEC 61131- 3\nImplement regulatory controls, sequencing logic, equipment controls, permissives, interlocks, alarms, diagnostics, and fault-response functions.\nDevelop or support human-machine interface and supervisory control functionality associated with assigned control systems.\nEstablish and follow software-development practices for code organization, naming conventions, peer review, testing, version control, configuration management, and release documentation.\nPerform peer reviews of control code and associated design documentation.\nDevelop simulation, emulation, or test environments to verify control-system behavior before deployment.\nInvestigate and resolve control-software defects, integration issues, communication problems, and unexpected system behavior.\nSupport controlled software installation, commissioning, turnover, and lifecycle maintenance.\nTechnical Leadership and Mentoring\nProvide technical guidance and mentoring to engineers, designers, technicians, and project-team members.\nLead technical reviews, design discussions, troubleshooting sessions, and resolution of complex control-system issues.\nReview the work of other engineers for technical accuracy, completeness, consistency, and compliance with project requirements.\nDevelop reusable design methods, standard architectures, templates, libraries, and engineering practices.\nShare lessons learned and promote continuous improvement in control-system design, software development, testing, and commissioning.\nSupport training and cross-training of engineers on applicable control platforms, design tools, and plant systems.\nServe as a technical resource to the
