Lead Mechanical Engineer (Mechatronics & EV Drivetrain) in St. Louis, Missouri at Intramotev

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.

• 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.

• 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.
