Company

hirify.global is a US-based global power company developing renewable energy and integrated power systems across multiple countries.

What you will do

• Lead integrated control architectures for solar PV, battery storage, fuel cells, synchronous generation, utility sources, switchgear, protection systems, and co-located critical loads.
• Define control philosophies, functional specifications, operating modes, control-authority boundaries, sequences, interlocks, fallback modes, and fail-safe behavior.
• Develop data center load integration, load-following, dispatch, reserve, energy-management, flexible-interconnection, curtailment, and ramp-rate control strategies.
• Lead control validation through EMT studies, PSCAD model reviews, CHIL/PHIL testing, vendor testing, laboratory testing, and site commissioning.
• Validate grid-connected and islanded operation, planned and unplanned islanding, synchronization, black start, restoration, load rejection, and recovery behavior.
• Serve as a technical authority, lead multidisciplinary reviews, guide vendors and partners, mentor engineers, and resolve first-of-kind system-control issues.

Requirements

• Master’s degree in controls engineering, power systems engineering, energy systems, electrical engineering, or a related field; PhD preferred.
• Typically 8–12 years of experience in utility-scale power systems controls, microgrids, utility-scale generation, energy storage, or advanced control applications.
• Deep understanding of grid-connected and islanded power systems, microgrid controls, grid-forming controls, synchronous generation, BESS, and renewable generation.
• Experience developing control architectures, control philosophies, operating sequences, operating modes, and advanced system-control algorithms.
• Experience with EMS, PPC, microgrid controllers, SCADA, and resource-level controls for integrated multi-resource systems.
• Strong knowledge of multi-resource dispatch, BESS state-of-charge management, load following, load smoothing, reserve management, and flexible interconnection controls.
• Working knowledge of PSCAD and EMT analysis, including reviewing models and simulation results for control interactions and system performance.
• Experience leading CHIL, PHIL, factory, laboratory, and integrated system testing for complex power-system controls.
• Knowledge of industrial communications, controls drawings, high-speed data acquisition, and protocols including Modbus, DNP3, and IEC 61850; field experience with system integration, commissioning, troubleshooting, and multi-OEM power systems.
