Location: Valencia, Valencia, Spain

Company

hirify.global develops integrated structural, electrical, and digital clean-energy solutions for utility-scale solar power plants, combining smart technology, data-driven insights, and automation.

What you will do

• Build and maintain PSCAD/EMTDC models of inverters and plants, including power stages, LCL filters, transformers, grid equivalents, and protections.
• Port C control code from Typhoon HIL into PSCAD and define model–control interfaces, including I/O, parameters, sampling, interpolation, and multirate behavior.
• Implement and validate grid-support functions such as LVRT/HVRT, P/Q control, Volt-VAr, Freq-Watt, ROCOF, GFL, and GFM modes.
• Develop automated PSCAD test suites with Python, parametric sweeps, signal extraction, performance metrics, and grid-code comparisons.
• Automate PSCAD, HIL, and PSS®E validation with time alignment, resampling, tolerance bands, KPIs, plots, and pass/fail reports.
• Integrate model builds, testing, and regression runs into GitLab CI/CD while maintaining libraries, schematics, parameters, versioning, guides, and customer support.

Requirements

• BSc or MSc in Electronic, Electrical, Industrial, or Telecommunications Engineering.
• 1–3+ years of experience in EMT simulation, model development, or validation tooling; junior candidates with a strong PSCAD-based master’s thesis are also welcome.
• Experience with three-phase inverters, PWM/SVPWM modulation, LCL filters, dq transformation, PLLs, current and voltage loops, and PI tuning.
• Strong C programming skills, including pointers, structs, and building and linking static and dynamic libraries.
• Python automation using NumPy, SciPy, pandas, and Matplotlib.
• Signal-processing knowledge including FFT, digital filters, phasors, symmetrical components, and resampling.
• Advanced PSCAD/EMTDC, C, and Python experience; intermediate experience with Typhoon HIL, Visual Studio or VS Code, Git/GitLab CI/CD, and MATLAB/Simulink.

Nice to have

• Experience with OEM models for interconnection studies and the PSCAD automation API or Typhoon HIL test automation.
• Knowledge of IEEE 1547-2018/1547.1, UL 1741 SB, NERC, or Spanish P.O. 12.2/NTS grid codes and test procedures.
• Experience with grid-forming control, including droop, VSM, virtual inertia, or black start.
• PSS®E experience with UDM, generic WECC models, or psspy.
• GitLab CI/CD, build scripting, basic Fortran, and intermediate PSS®E experience.

Culture & Benefits

• Work within worldwide teams developing clean-energy infrastructure for utility-scale solar power plants.
• Contribute to smart technology, data-driven insights, and advanced automation for faster project delivery, higher performance, and reliability.
