Lead PLC Engineer

Headquartered in Dallas, Texas, Divcon delivers fully integrated automation solutions nationwide that optimize performance, energy efficiency, and reliability across HVAC, lighting, power monitoring, and mission-critical systems. Leveraging advanced technologies - including Allen-Bradley PLCs, Ignition SCADA, and Delta DDC systems - we combine deep technical expertise with field-tested execution to deliver precise, scalable, and high-performance solutions.

The Lead PLC Engineer is a senior technical leader responsible for the design, development, and delivery of PLC-based control systems across complex, large-scale projects.

This role combines deep hands-on programming expertise with technical leadership, guiding engineering standards, mentoring team members, and ensuring high-quality, consistent execution across projects.

You will play a critical role in defining control strategies, standardizing PLC architecture, and ensuring seamless integration with SCADA and facility systems in high-performance environments.

• Lead the design and development of PLC control systems using platforms such as Rockwell / Allen-Bradley (Studio 5000).
• Establish and maintain PLC programming standards, reusable code libraries, naming conventions, and best practices.
• Define system architecture including control strategies, I/O structures, network design, and redundancy approaches.
• Ensure consistency and quality across all PLC deliverables through design reviews and code validation

• Own PLC scope across multiple projects, from design through commissioning and turnover.
• Develop and implement control logic for HVAC systems, central plants, and critical infrastructure systems.
• Support system integration with SCADA platforms (e.g., Ignition), BMS, and EPMS systems.
• Collaborate with project managers, engineers, and field teams to ensure alignment on scope, schedule, and deliverables.
• Lead troubleshooting and resolution of complex control system issues during startup and commissioning.

• Mentor and guide junior and mid-level PLC engineers, providing technical direction and support.
• Review engineering work and provide feedback to ensure adherence to standards and best practices.
• Support onboarding and training of new team members.

• Participate in client-facing meetings, providing technical expertise and guidance on automation solutions.
• Work closely with SCADA engineers, field technicians, and system integrators to ensure seamless system deployment.
• Interface with vendors and contractors to support system integration and issue resolution

• Drive improvements in engineering processes, tools, and workflows to increase efficiency and scalability.
• Identify opportunities to standardize and automate development processes.
• Stay current on emerging technologies and trends in PLC programming, industrial automation, and data center systems.

• 7+ years of experience in PLC programming and industrial automation.
• Strong expertise with Rockwell / Allen-Bradley (Studio 5000) platforms.
• Proven experience designing and implementing control systems for HVAC, central plants, or similar mechanical systems.
• Experience with system integration, commissioning, and troubleshooting in field environments.
• Strong understanding of industrial communication protocols (Ethernet/IP, Modbus TCP, BACnet/IP, OPC-UA).
• Demonstrated ability to lead technical efforts and mentor engineers.
• Excellent problem-solving, communication, and organizational skills.

• Experience in data centers or high-availability environments.
• Familiarity with Ignition SCADA, Kepware, or similar platforms.
• Experience with redundant PLC architectures and high-availability systems.
• Exposure to BMS/EPMS integration.
• Bachelor’s degree in Electrical, Mechanical, or Automation Engineering (or equivalent experience).
