• Support development of standardized hardware and software products, including PLC-based panels, monitoring systems, cloud SCADA offerings, and future industrial automation solutions.
• Strengthen engineering practices for requirements management, design review, configuration control, testing, FAT readiness, release management, and change control.
• Develop and execute test plans, FAT procedures, verification checklists, release notes, and technical documentation.
• Troubleshoot complex technical issues across controls, SCADA, networking, databases, communications, and field integration.
• Support Sales in technical discovery calls, client workshops, site walks, solution presentations, estimates, proposal narratives, technical clarifications, and statements of work.
• Mentor SCADA Engineers, Control Systems Engineers, software-oriented Automation Engineers, analysts, and junior technical staff.
• Collaborate with SCADA leadership, Technical Services, Project Delivery, and other technical leaders to improve engineering consistency, handoffs, commissioning readiness, and delivery quality.
Required Qualifications:
• 8+ years of experience in industrial automation, controls engineering, SCADA engineering, systems integration, or related technical roles.
• Strong hands-on experience developing and delivering PLC, HMI, and SCADA solutions.
• Ability and willingness to personally execute development work while also providing architecture, mentorship, and technical leadership.
• Experience with at least one major SCADA platform such as Ignition, Cygnet, Wonderware/AVEVA, VTScada, or similar.
• Experience designing and supporting systems involving PLCs, RTUs, HMIs, SCADA servers, historians, databases, and industrial networks.
• Strong understanding of industrial protocols such as Modbus, OPC UA, MQTT/Sparkplug B, DNP3, and EtherNet/IP.
• Ability to develop and review control logic, HMI/SCADA configurations, architecture diagrams, test plans, and commissioning documentation.
• Experience mentoring engineers, leading design reviews, developing standards, or serving as a technical lead.
