Job description
The Power Supply Lead Engineer (Railway Traction Systems) at Alstom in AlUla, Saudi Arabia is responsible for leading MV/LV traction engineering activities within railway transportation projects including metro, tramway, and mainline systems. The role involves executing both basic and detailed engineering for HV power supply systems, MV power supply systems, LV power supply systems, and DC traction systems, ensuring compliance with Design for Quality standards and delivering optimized performance and reliability. The engineer develops comprehensive electrical architectures and prepares technical specifications, functional specifications, and interface specifications while conducting clause-by-clause reviews and gap analysis. Responsibilities include performing detailed calculation notes such as short circuit calculations, cable sizing, power balance analysis, power factor study, UPS sizing, battery sizing, earthing systems, protection coordination, MCB coordination, and basic structural calculations. The position requires managing interfaces between power supply subsystems and other subsystems such as Systems, RAMS, EMC, Procurement, and Civil Works, while coordinating with local utility providers. The role includes defining subsystem architecture, operational modes, and functionalities in collaboration with DC traction equipment suppliers, and writing subsystem specifications. The engineer contributes to procurement processes by preparing technical purchasing specifications, evaluating supplier offers, validating documentation, defining standards, and participating in factory acceptance tests. The role also involves executing Verification & Validation (V&V) strategies, supporting construction and Testing & Commissioning teams, conducting site testing and commissioning activities, resolving site technical issues, implementing modifications, and ensuring closure. Additionally, the engineer performs KPI reporting, supports engineering risk mitigation plans, manages change orders, optimizes QCD (Quality, Cost, Delivery), and participates in design reviews. The role requires proficiency in tools such as ETAP, SKM, CYMCAP for MV network sizing and cable sizing, as well as AutoCAD, with working knowledge of BIM, Revit, and Navisworks, within a multidisciplinary railway engineering and project management environment.
