Key Responsibilities

Responsible for the design of power plant monitoring and control systems (DCS, SCADA, PLC and Special Function Controllers) and related control devices/subsystems used for data acquisition, automatic process control, safety & reliability and operator stations/interfaces. An ideal candidate is expected to have the following:

• Deep understanding of customer (power plant owners) requirements (plant layout, monitoring & control requirements of power plant [Generator, GT, ST, Boiler, HRSG, BoP and Auxiliaries – respective open loop, closed loop controls and protection interlocks]), P&ID, and Functional Design Specifications
• Ability to understand and interpret P&IDs, Plant Layout and Control System Architecture, Functional Design Specifications, Control Philosophies & Control Narratives, Cause & Effect Matrices/diagrams
• Ability to design the entire control system software (system configuration, control logics implementation, HMI building and Alarm & Event Management) in collaboration with related technical departments.
• Well-versed with DCSs’ IO Databases, Alarm & Event Configuration, using HMI builder to create and link screens, control and interlock logic programming using Ladder Logic, Function Block Diagrams (FBD), Structured Text (ST) and Sequential Flow Charting (SFC). Experience and good understanding of IEC61131 based programming. Knowledge of Problem Oriented Language (POL) is a plus
• Knowledge of Network & Cyber Security Configurations
• Prepare system software configuration documentation. Review vendor documentation and technical submittals
• Knowledge of applicable international standards (IEC 61850, IEC60870, DNP3 etc.)
• Minimum of 5 years’ experience in design and detail engineering of one or more established DCS used in power plants. Example: Diasys Netamation, MELSEP, HIACS, TOSMAP, SPPA T3000, Mark VIe, Symphony Plus, 800xA, Emerson, Honeywell, Centum•

We are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach. Our teams regularly invest time and dedicated effort into internal culture work, ensuring that all voices are heard.

We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.
