Applications Engineer/BAS Programmer

The BAS Controls Programmer is responsible for developing, configuring, testing, and deploying building automation control systems used in commercial, industrial, and mission-critical facilities.

This role transforms mechanical and electrical design intent into fully functional control logic using DDC, PLC, and BAS programming tools.

You will work closely with design engineers, project managers, and field technicians to ensure every system operates safely, efficiently, and according to specification.

• Develop and program DDC controllers, including logic, sequences, alarms, schedules, and trends.
• Build and configure controller databases, graphics, navigation, and user interfaces.
• Implement integration using BACnet, Modbus, and other open protocols.
• Configure and test network settings, IP addressing, routing, and device bindings.
• Create and update programming libraries, templates, and standards.
• Support field technicians during startup, commissioning, point-to-point testing, and functional testing.
• Troubleshoot communication issues, device failures, programming errors, and performance gaps.
• Perform on-site adjustments to optimize HVAC and mechanical system performance.
• Validate I/O lists, mechanical schedules, control drawings, and sequences of operation.
• Maintain organized project files including backups, version control, release notes, and as-built documentation.
