What You Will Do

- Interpret project specifications, sequences of operation, plant schematics, system architecture drawings, and customer requirements to develop effective BMS software solutions.

- Design, develop, configure, and maintain DDC and PLC application software using proprietary programming platforms and industry-standard programming methodologies.

- Develop control strategies, logic diagrams, functional sequences, alarms, trends, schedules, and supervisory control applications.

- Configure and integrate BMS communication protocols including BACnet, LonWorks, Modbus, OPC, and other applicable automation standards.

- Engineer complete HVAC control solutions for air handling units, chiller systems, boiler plants, variable air volume systems, and related mechanical equipment.

- Troubleshoot software control loops and optimize system functionality to achieve operational and performance requirements.

- Perform offline programming, simulation, testing, and Factory Acceptance Testing (FAT) activities to ensure robust and reliable system performance.

- Conduct functionality verification against project requirements, specifications, and sequences of operation.

- Collaborate closely with design engineering, graphics engineering, commissioning, and project execution teams to ensure timely project delivery.





- Produce clear technical documentation, testing records, software backups, and project deliverables in accordance with company standards.

- Manage engineering tasks and deliverables while maintaining project schedules, reporting progress, and communicating technical risks.

- Support continuous improvement initiatives, reusable software libraries, engineering standards, and best practices
