• 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.
