About the job

We're on a growth journey, driven by deep knowledge and skilled colleagues shaping the future of energy. Together, we deliver smart, scalable solutions that help our clients succeed in the energy transition. Do you want to be part of igniting what's next in energy? Join us.

Opoura’s Power Engineering department is a highly specialized team working with grid connection studies and advanced power system modeling. We help customers connect new or upgraded power plants in line with TSO and DSO requirements, and we develop and maintain the models used in Opoura’s control products and in external customer applications.

Based in Porto, you will join a team that collaborates closely across Portugal and Denmark, and works side by side with Software and SCADA colleagues to make sure control requirements and operational realities are reflected in our analyses.

Your role

As our Grid Analyst Engineer, you will contribute to technical delivery across customer and internal projects. You will support grid studies and modeling work, translate grid requirements into study inputs and modeling assumptions, and build depth in the tools and methods used in real projects.

Key responsibilities

Your main responsibilities as our Grid Analyst Engineer will be:

• Interpret and analyze grid codes and interconnection requirements, and translate them into study inputs and modeling assumptions

• Build, validate, and maintain power system models and run simulations in tools such as DIgSILENT PowerFactory, PSS/E, PSCAD, and TSAT

• Develop aggregated plant representations for grid approval, integrating multiple generation technologies including PV, wind, and battery energy storage systems (BESS)

• Run and document grid operation studies in line with regulatory requirements, including power flow, short-circuit, and fault analysis, plus relevant dynamic studies

• Support control modeling and validation activities in MATLAB/Simulink

• Contribute to automation and implementation tasks using Python and/or C/C++ to improve model quality and workflow efficiency

To be successful in this position, you:

• Manage multiple project contributions in parallel while meeting quality expectations and agreed deadlines

• Demonstrate strong team spirit by supporting colleagues, collaborating across projects, and proactively seeking or offering help when needed

• Apply a pragmatic, solution-oriented approach to technical challenges and communicate clearly when something needs attention

• Develop and maintain a solid understanding of power system operation and analysis, including power flow, short-circuit, and fault studies

• Build a strong foundation in control systems and how they interact with grid requirements

Your background

You are a results-driven team player who likes getting to the bottom of technical problems without overcomplicating them. You take ownership of your work, bring a practical mindset, and learn quickly through hands-on delivery and feedback.

• 2+ years experience in power system modeling or a closely related engineering role

• Degree in Electrical Engineering (or similar)

• Experience with PSS/E and PSCAD, and preferably also DIgSILENT PowerFactory

• Working knowledge of Python and/or C/C++ for implementation or automation tasks

• Experience with MATLAB/Simulink from work, thesis, or project settings

• Fluent in English and Portuguese

• Able to be in the Porto office at least 2 days per week
