About Job

Intramotev is seeking a motivated Lead Mechanical Systems Engineer to join the development team to meet growing demands in the development of self-propelled rail vehicles.

This role focuses on the complex mechanical integration of electric propulsion systems—including motors and gearboxes—with railcar axles and bogie structures.

Skills & Qualification

  • At least a Bachelor’s Degree in Mechanical Engineering or a related field.

  • 5+ years of experience in electromechanical/multidisciplinary product design.

  • Proficiency in 3D mechanical design using Autodesk Inventor or similar CAD tools.

  • Proven experience with structural analysis (FEA) and GD&T.

  • Will to expand into technical areas beyond your area of expertise; ability to develop innovative and novel approaches.

  • Open-minded and comfortable working in a teaming environment as a technical leader.

  • Fluent in both written and verbal English.

    Preferred Qualifications

    • Experience with Rail Vehicles, Bogie Architectures, or Braking Systems.

    • Direct experience with EV Powertrain integration, including e-axle development.

    • Knowledge of thermal management systems for power electronics and motors.

    • Demonstrated experience working across organizational boundaries and leading technical teams.

Responsibilities

  • Lead the mechanical integration of supplier-provided electric motors and gearboxes into existing railcar bogie architectures.

  • Translate powertrain requirements into detailed interface specifications, focusing on axle integration and clearance for brake linkages.

  • Design and optimize mounting solutions and enclosures for propulsion components within the highly constrained environment of a rail bogie.

  • Perform structural and stress analysis using CAD and FEA tools to ensure integrated components withstand heavy rail operational loads.

  • Lead functional and operational testing of the integrated drivetrain to ensure performance and safety requirements are met.

  • Collaborate with electrical and software teams to define functional interfaces for motor control and thermal management.

  • Provide comprehensive support for fielded systems, resolving integration or performance issues throughout the product lifecycle.

  • Work within dynamic teams of 3-10 members on diverse projects.

  • Foster excellent interpersonal and communication skills to thrive in a collaborative environment.

  • Adapt to evolving project objectives and requirements as the technology advances.

  • Engage in occasional domestic travel to support integration, demonstration, and customer interactions.

  • Manage the packaging constraints of brake linkages, structural frames, and thermal systems.
