POSITION OVERVIEW
The Principal Instrumentation & Controls Engineer is accountable for the overall control, automation, and operational intelligence of utility-scale gas-fired power plants, including gas turbine– and gas fired reciprocating engine–based generation facilities.
This role serves as the owner-side technical authority for all instrumentation & control-related systems across the full project lifecycle—from early development and Pre-FEED through EPC execution, commissioning, and operations. The Principal defines control philosophy, governs EPC and OEM designs, and ensures reliable, high-availability operation, particularly for mission-critical loads such as data centers.
This position owns the integration and performance of multi-layer control architectures, including engine package controllers, plant-level PMS, and supervisory EMS.
The employee may be required to perform other job-related duties as requested by management. All duties will be assigned in accordance with applicable laws and company policies.
