Job Description Summary

Job Description Summary En tant qu’Ingénieur référent technique sur les disjoncteurs courant continu, vous serez rattaché(e) au Responsable de l’équipe \"Electrical Valve Engineering\", de la Solution Line HVDC (l'équipe en charge des projets de développement et des projets clients pour les valves de conversion HVDC*). Sur ce poste, votre mission consistera à coordonner et préparer les options et décisions techniques dans le cadre du développement du produit. Votre rôle sera de garantir que les choix techniques, depuis la phase de conception préliminaire jusqu’aux phases de conception détaillée, sont pertinents afin d’assurer les performances spécifiées du disjoncteur, ainsi que sa fiabilité et sa qualité. Votre rôle consistera également à établir les capacités techniques propres à la technologie et aux applications DCCB**. Intégré(e) à la fonction \"Valve Converter Engineering & Technology\", vous pourrez également être impliqué(e) dans la conception et l’amélioration de produits de valves de conversion existants. Le/la candidat(e) retenu(e) fera partie d’une équipe d’ingénieurs hautement motivée et dynamique, travaillant sur la livraison et l’ingénierie d’application de solutions existantes et nouvelles en électronique de puissance pour les réseaux électriques, en particulier pour les convertisseurs HVDC ainsi que les futurs réseaux « HVDC Grid » et « MTDC Grid ». Il s’agit d’un domaine de l’ingénierie électrique particulièrement stimulant et dynamique, dans lequel GE Vernova joue un rôle de premier plan et bénéficie d’une reconnaissance mondiale.

On as Technical Lead DC Circuit--Breaker Engineer, you will report to the Valve Engineering Electrical Team Lead within the HVDC Solution Line (Team who deliver development project and customer projects for the HVDC Converter Valve). As Lead engineer DC Circuit-Breaker, your mission will be to coordinate and prepare the technical options and decisions in the development of the product. Your role is to ensure that the technical choices, from concept design to detailed design stages, are relevant to ensure the specified performance of the DCCB product and ensure DCCB product reliability and quality. Your role is also to establish the technical capabilities that are specific to the DCCB technology and application. Being integrated in the Valve Converter Engineering & Technology Function, you could also be involved in the design and improvement of existing converter valve products. The successful candidate will be part of a highly motivated, dynamic team of engineers working on the delivery, application engineering of existing and new power electronics applications for power systems, particularly for HVDC converters and the forthcoming “HVDC Grid” and “MTDC Grid”. This is a very exciting and dynamic field of power engineering in which GE Vernova has a leading contribution and worldwide recognition.

Responsibilities

• Generate project documentation (such as type test specification, type test reports, design reports…)
• Validate key component ratings (size of the components, calculation of losses, RAM study…)
• Perform the detailed design of the DCCB sub‑module
