The Opportunity
The Commissioning Engineer will lead and execute advanced commissioning activities across mission‑critical projects, with a focus on BMS, EPMS, PLC, and SCADA systems. This role goes beyond field validation, requiring the ability to diagnose system issues, modify and develop control logic, and support system integration during commissioning and delivery phases.
Working closely with Engineering, Integration, and Operations teams, you will play a key role in ensuring systems are not only installed correctly, but functionally robust, fully integrated, and aligned with design intent and operational requirements.
This position is ideal for an experienced commissioning professional with strong controls expertise, capable of bridging the gap between design, software, and field execution in high‑availability environments.
This position is ideal for professionals who value accountability, technical rigor, and hands‑on execution in environments where safety, performance, and reliability matter every day.
