Are you ready to embark on an exciting journey with Coreso, a dynamic and fast-paced company at the forefront of the European energy landscape? As a Regional Coordination Center (RCC), Coreso plays a crucial role in coordinating high-voltage electricity flows for European Transmission System Operators (TSOs), ensuring the security of electricity supply on a regional basis.
Our teams work on complex coordination services that support system security, efficient electricity exchanges, and the integration of renewable energy across national borders.
Your new career in Coreso
As Senior Service Engineer, you play a key role in the development and evolution of coordination services that support the secure operation of the European electricity grid.
You contribute deep technical expertise to the design, implementation and continuous improvement of methodologies used by Coreso and its partners to coordinate cross-border electricity systems. Working closely with operational teams, IT specialists, TSOs and other RCCs, you help translate regulatory requirements and operational challenges into robust service methodologies and practical solutions.
In addition to your technical contributions, you act as a recognised expert within your domain. You contribute to complex service development initiatives, participate in technical discussions across the European coordination ecosystem, and support colleagues in navigating complex technical questions related to service design and implementation.
Through this role, you contribute to strengthening the reliability, efficiency and resilience of the European electricity system in a context of increasing renewable integration, growing interconnection and evolving regulatory frameworks.
Your role as a Senior Service Engineer consists of the following responsibilities:
Develop and evolve coordination services that support European power system operations, with a strong focus on flow-based capacity calculation methodologies and cross-border market coordination.
Translate regulatory and operational requirements into structured methodologies, analytical approaches and service processes used by Coreso and its partners.
Provide expert technical contributions to complex service development initiatives, working closely with operational teams, IT specialists and other domain experts.
Collaborate with TSOs, RCCs and European working groups to design, validate and improve coordination methodologies applied across the interconnected grid.
Support the implementation and validation of services, including testing, tooling integration and deployment in operational environments.
Share and strengthen expertise within the organisation, contributing to knowledge development, technical discussions and the guidance of less experienced colleagues.
What are we looking for?
You hold a Master’s degree (or equivalent experience) in electrical engineering, power systems, applied mathematics or a related technical field.
You bring substantial experience (typically around 8–10 years) working with power systems, electricity markets or grid operations.
You understand the technical and operational challenges of coordinating electricity systems, ideally in a multi-stakeholder environment.
You are comfortable working with complex analytical problems and translating them into practical methodologies or solutions.
You enjoy working with experts from different organisations, such as TSOs, RCCs or other actors in the European energy ecosystem.
You communicate clearly and can explain complex technical concepts to different stakeholders, both internally and externally.
Fluent English. Any other European language is an asset.
Coreso is the Regional Coordination Service Centre subsidiary of 50Hertz Transmission (Germany), EirGrid (Ireland), Elia (Belgium), National Grid ESO (United Kingdom), REE (Spain), REN (Portugal), RTE (France), Terna (Italy) and SONI (Northern Ireland). The area monitored by Coreso's Brussels-based technical coordination centre covers 275 million customers, some 54% of the European Union’s population.
Coreso started its operations in February 2009 and is the first joint technical coordination centre owned by several transmission system operators. Coreso has delivered substantial improvements in operational coordination between transmission grids in response to new challenges. The growth of renewable energy sources – characterized by their variable output - coupled with the rise in cross-border exchanges in the European electricity market, are leading to increasing fluctuation in power flows. Coreso has developed a high degree of reliability and expertise. On several occasions, Coreso demonstrated its value by identifying in the electrical system risk situations that are only detectable by an overall sharing, beyond the national perimeter of each individual transmission network.
In practice, Coreso provides the control centres of participating TSOs with detailed forecasts of network security in this extended coverage zone, by producing security analyses, simulating a range of different scenarios and suggesting coordinated measures. Coreso coordinates exchanges between the national control centres, which remain operationally responsible on their respective networks.
