• Strong theoretical and practical understanding of power electronics converters, control systems, and electrical machines.
• Proven experience in dynamic system modelling and simulation of converter-based power systems.
• Expertise with modelling and simulation tools, such as MATLAB/Simulink, PLECS, PSCAD, PSSE, DIgSILENT, or Modelica.
• Understanding of control design, signal processing, and system stability theory.
• Knowledge of grid integration challenges in renewable or converter-dominated networks (e.g., wind, solar, HVDC, microgrids).

• Experience with real-time simulation platforms (e.g., OPAL-RT, Typhoon HIL, RTDS).
• Familiarity with EMT, RMS, and hybrid simulation techniques for multi-timescale studies.
• Experience in harmonic analysis, electromagnetic transient analysis, or EMC/EMI modelling.
• Background in co-simulation frameworks combining electrical, thermal, and mechanical domains.
• Strong programming and scripting skills (e.g., MATLAB, Python, C/C++, Modelica, or VHDL-AMS).

• Strong analytical and problem-solving mindset with a passion for technical innovation.
• Strong report writing skills; writes clearly and succinctly to meet the needs and understanding of the intended audience.
