Senior Control Engineer

The Senior Control Engineer leads the design, development, and testing of control and electrical systems for Dunham-Bush chiller, airside, and package products. This role carries a strong background in the HVAC industry, particularly chiller control systems, and takes ownership of DDC and/or PLC control logic development and programming, BMS communication and networking integration, and graphical user interface (GUI) development. Knowledge of Turbocor or centrifugal compressor control sequences is a strong added advantage.

The Senior Control Engineer works with greater independence than a Controls Engineer, provides technical leadership on complex control projects, and mentors junior engineers.

• Leads development and programming of DDC and/or PLC control logic and operation sequences for chiller, airside, and package products.
• Serves as the technical subject matter expert on HVAC chiller control systems; knowledge of Turbocor or centrifugal compressor control sequences is a strong added advantage.
• Designs and develops graphical user interfaces (GUI) for unit controllers, local displays, and/or remote monitoring tools, ensuring intuitive and reliable operator interaction.
• Leads interfacing and integration of Building Management System (BMS) communication (e.g., BACnet, Modbus, Lon Works), networking, and other high-level communication protocols between DB equipment and third-party systems.
• Primarily responsible for electrical starter and control panel design, switch board fabrication, and oversight of manufacturing plant facilities.
• Responsible for the installation and technical support of DDC controller-based hardware and software configurations and operation sequences.
• Designs, develops, and supervises all aspects of electrical control systems, equipment, and machinery.
• Prepares design documents (electrical data, drawings, operation manuals, etc.) for new and current product platforms.
• Reviews factory orders for compliance with applicable standards, customer requirements, and sound engineering principles and practices.
• Prepares documentation required for special/highly customized projects, including drawings, purchased part specifications, procedures, and bills of material.
• Performs hands-on electrical panel testing, troubleshooting, procedures, and safety compliance.
• Provides technical support to Sales/Marketing, Warranty Service, Quality Control & Production Departments, Associate Companies, and Customers as needed.
• Provides technical mentorship and guidance to junior Electrical/Controls Engineers.
• Assists the Purchasing Department in sourcing components and raw materials, providing specifications, and evaluating vendor quality.
• Performs any other duties as assigned by the Engineering Manager or as detailed in company documents.
• The Company may at any time, as deemed necessary, add or amend any of these job responsibilities.

• Strong background in the HVAC industry, especially chiller control systems; knowledge of Turbocor or centrifugal compressor control sequences is a strong added advantage.
• Proficient in development and programming of DDC and/or PLC control logic.
• Experience interfacing BMS communication protocols (e.g., BACnet, Modbus, Lon Works), networking, and high-level communication between control systems.
• Experience developing graphical user interfaces (GUI) for equipment control and monitoring.
• Sound electrical engineering knowledge and practice.
• Good written and verbal English communication skills.
• Very proactive, innovative, team-player, analytical-minded; able to lead technical projects with minimal supervision.

• Bachelor's degree in Electrical Engineering or related field.
• 5-8 years of relevant working experience, with a strong HVAC or related manufacturing background and demonstrated PLC/DDC programming skills.
• Experience with Turbocor or centrifugal compressor control sequences is a strong added advantage.
• Experience with BMS integration, networking, and GUI/HMI development strongly preferred.
• Product safety certification process, ETL and AHRI relevant experience will be an added advantage.
