Senior Design Engineer

About Us:

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.

About the role:

As a Senior Design Engineer, you will lead the design, documentation, and implementation of complex building automation and control systems for commercial, industrial, and mission-critical facilities. You’ll serve as both a technical authority and mentor, ensuring that Divcon’s automation solutions are designed with precision, scalability, and performance in mind. This role bridges electrical design, control logic development, and project leadership — ensuring every system meets customer expectations, industry standards, and energy efficiency goals.

Key Responsibilities:

• Lead the technical design of HVAC and building automation control systems, including control schematics, riser/network diagrams, panel layouts, and point-to-point wiring details.
• Translate mechanical/electrical plans and specifications into full automation control designs, ensuring seamless integration with mechanical sequences of operation (SOO).
• Develop and review control submittals, bill of materials (BOMs), and control device specifications for procurement and fabrication.
• Apply and enforce NEC, NFPA, ASHRAE, and UL standards in all designs.

• Conduct QA/QC reviews of control drawings, submittals, and as-builts to ensure quality and compliance.
• Support commissioning and startup by collaborating with software and installation teams, troubleshooting control and network issues as needed.
• Develop sequence of operations documentation, logic diagrams, and control narratives for advanced mechanical systems.

• Engineer system architectures involving BACnet, Modbus, and IP-based networks, integrating HVAC, lighting, and metering systems.
• Design custom control panels and assist in panel shop build verification or FAT/SAT testing.
• Evaluate and implement new control hardware, sensors, and energy optimization strategies to enhance performance.
• Work with IT and software teams to support cybersecurity, connectivity, and system resiliency in networked BAS deployments.

• Provide technical mentorship to junior and intermediate designers, supporting their growth in BAS, electrical design, and documentation standards.
• Collaborate cross-functionally with mechanical, software, and commissioning teams to resolve design challenges and maintain project schedules.
• Contribute to internal standards development, drafting best practices for submittal templates, CAD standards, and design workflows.

Qualifications:

• Bachelor’s degree in Electrical, Mechanical, or Controls Engineering, or equivalent experience.
• 5+ years of progressive experience in building automation, MEP design, or industrial controls.
• Demonstrated ability to produce and review AutoCAD or AutoCAD Electrical drawings and submittal packages.
• Hands-on experience with control systems communication protocols (BACnet, Modbus, LonWorks, etc.).
• Familiarity with DDC system architecture, field controllers, and point mapping for HVAC systems.
• Strong understanding of sequence of operations, mechanical integration, and power distribution basics.
• Knowledge of applicable codes and standards: NEC, NFPA, UL 508A, ASHRAE 135, and local energy codes.
• Excellent organizational, documentation, and communication skills.

Preferred:

• Experience with PLC/HMI programming or troubleshooting (Allen-Bradley, Schneider, Siemens, etc.).
• Field or commissioning exposure — FAT/SAT testing, control panel fabrication, or on-site startup.
• Prior leadership of small design teams or project-level ownership of BAS packages.
• Proficiency in ETAP, SKM, or similar tools for electrical analysis.
• P.E. or E.I.T. license preferred but not required.
