Principal Power Systems Engineer

We are now looking for a

Principal Power Systems Engineer

to join our team working for a better future.

The position is permanent, and the preferred location is the UK.

What you will be doing

We are seeking a Senior Power Systems Engineer to play a key role in advancing our electrical and power systems modeling tools. As a Principal Power Systems Engineer, you will be responsible for dynamic modeling of inverter-based resources, with a primary focus on battery energy storage systems (BESS) in software tools like DIgSILENT. Your expertise will be instrumental in grid code analysis and stability assessments of utility-scale standalone BESS as well as hybrid BESS power plants integrated with solar PV systems. This position is an integral part of our Power Systems and Data Science team within a Research and Development capacity, contributing to the evolution of our software capabilities and supporting new product development for automated power system optimization.

As the Principal Power Systems Engineer, your work will focus on these responsibilities:

• Develop, implement, and optimize dynamic models for battery energy storage systems.
• Translate data models and algorithms into functional software, conducting rigorous simulation tests to evaluate model performance.
• Collaborate closely with our software solutions team and hardware testing team to leverage data for detailed battery system modelling.
• Enhance internal models and tools to expedite product development.
• Create comprehensive documentation outlining algorithm and model improvements, with clear justifications for new methodologies.
• Interpret specifications and electrical drawings for large energy project sites that include thermal generation, renewable generation (PV or Wind), and energy storage.
• Flexibility to support tasks outside the defined job description as needed, adapting to a dynamic work environment.

To be successful in this role, we expect you to have:

• Master's or Ph.D. degree in power systems engineering, electrical engineering, or a related field.
• Strong foundational knowledge of electrical engineering principles.
• Proven experience in modelling inverter-based resources.
• Proficiency with software tools such as PSCAD, DIgSILENT, and PSS/E.
• Self-motivated and capable of independent work.

(In this role, some travel is required to meet with our customers around the world. Thus, we hope you to be ready to travel approximately 20%, even though most of the meetings are held virtually.)
