Job summary

SEGULA Technologies is a leading global consultancy and engineering firm providing lifecycle support across automotive, aerospace, energy and rail sectors. This role focuses on defining requirements, interfaces and vehicle-level propulsion architectures for high-voltage systems and power transmission.

You will collaborate with suppliers, perform system definition and performance analysis, evaluate vehicle dynamics, integrate traction power converters, and coordinate with software and mechanical

Responsibilities

• Define requirements, manage interfaces, and design vehicle-level concepts and propulsion system architectures for the propulsion and power transmission chain: from high-voltage energy captation systems to internal power conversion and distribution, ensuring traction performances, safety, energy efficiency, and reliability standards.
• Supplier Management: Collaborate with suppliers to develop precise specifications for high-voltage captation components and custom propulsion solutions. Define Technical Purchase Specifications, prepare Bills of Materials (BOMs), manage requirements using DOORS, prepare clause-by-clause evaluations, and verify schematic diagrams.
• System Definition & Performance Analysis: Create system and functional specifications, conduct precise component sizing, execute traction performance and energy consumption calculations, manage the high-voltage power supply chain, and run detailed performance and line-interaction simulations.
• Vehicle Dynamics & Performance Evaluation: Apply knowledge of acceleration, maximum speed, and vehicle performance parameters to model, evaluate, and optimize overall traction capabilities across varying operating profiles.
• Converter & Inverter Integration: Define technical specifications and requirements for traction power converters and inverters, ensuring seamless functional, mechanical, thermal, and electrical integration into the overall vehicle architecture.
• System Integration: Coordinate with other engineering departments (software, schematics, and mechanical teams) to integrate electrical subsystems into the vehicle.
• Testing & Technical Analysis: Participate in design reviews, technical analyses, prototyping, and on-site testing to ensure functional consistency and compatibility across systems. Define and support test specification creation.

Job description

SEGULA Technologies is a leading global consultancy and engineering firm. We support our clients throughout every stage of their products' lifecycle in sectors such as the automotive, aerospace, energy and rail industries, amongst others.

With a presence in over 30 countries and a team of more than 10,000 experts, we are driven by innovation, digital technology and a strong commitment to inclusion and diversity.

Functions:

• Define requirements, manage interfaces, and design vehicle-level concepts and propulsion system architectures for the propulsion and power transmission chain: from high-voltage energy captation systems (pantograph, circuit breaker, roof disconnectors, earthing switches, main transformer, monitoring components, etc.) to internal power conversion and distribution, ensuring traction performances, safety, energy efficiency, and reliability standards.

• Supplier Management: Collaborate with suppliers to develop precise specifications for high-voltage captation components and custom propulsion solutions. Define Technical Purchase Specifications, prepare Bills of Materials (BOMs), manage requirements using DOORS, prepare clause-by-clause evaluations, and verify schematic diagrams.

• System Definition & Performance Analysis: Create system and functional specifications, conduct precise component sizing, execute traction performance and energy consumption calculations, manage the high-voltage power supply chain, and run detailed performance and line-interaction simulations.
