Mechanical Design Engineer - Drivetrain

About Us

At Intramotev, we are liberating tons of freight from congested highways, reducing carbon emissions, and enhancing transportation efficiency. We are deploying self-propelled battery-electric railcars and vehicles to transform freight logistics and bring innovation to our rail network. Based in St. Louis, MO, we are committed to industrial revitalization and building a safer, cleaner rail industry.

About the Role

We are seeking a Mechanical Design Engineer to support the drivetrain program, translating drivetrain engineering direction into detailed manufacturing and assembly drawings for powertrain hardware — motor/gearbox interfaces, mounting solutions, enclosures, and axle and bogie integration hardware. You'll start by producing drawings that support the build of a drivetrain test stand, then take on detailed design ownership of drivetrain subsystem hardware within your first several months on the program. This is a full-time, 100% in-office role based in St. Louis, MO. You'll work within a team of 3–10 engineers and engage in occasional domestic travel for testing, integration, and demonstrations.

Responsibilities

• CAD & Drawing Development: Author 3D CAD models for drivetrain components — motor/gearbox interfaces, mounting solutions, enclosures, and axle/bogie integration hardware — handed off by the drivetrain lead.
• Manufacturing & Assembly Drawings: Produce detailed manufacturing and assembly drawings, applying GD&T, for drivetrain components to support fabrication and build.
• Test Stand Support: Translate drivetrain test-stand requirements into fixture and bracket drawings.
• Fabrication & Build Support: Support fabrication and assembly of the test stand and troubleshoot fit-up issues during build.
• Subsystem Design Ownership: Take on detailed design ownership of drivetrain subsystem hardware — mounting solutions, brackets, enclosures, and interface hardware — under the drivetrain lead's technical direction, starting within your first several months on the program.
• Collaboration: Work closely with the drivetrain lead and the Mechanical Engineering Team Lead to clarify ambiguous or partially-specified requirements and keep drawings aligned to fabrication and assembly needs.

Qualifications

Basic Qualifications (Required Skills/Experience)

• Bachelor's degree in Mechanical Engineering or a related technical field.
• 2–4 years of mechanical design experience, including creating manufacturing/assembly drawings with GD&T, using 3D CAD tools such as Autodesk Inventor or equivalent.
• Willingness to expand into technical areas beyond your area of expertise; ability to develop innovative and novel approaches.
• Comfortable working from ambiguous or partially-specified requirements handed off by a technical lead.
• Open-minded and comfortable working in a teaming environment as an individual contributor.
• Fluent in both written and verbal English.
• Authorized to work in the U.S. at time of hire without employer-sponsored visa status (OPT/F-1 practical training authorization acceptable); no sponsorship provided to reach a start date, but Intramotev is open to sponsoring continued work authorization (e.g. an H-1B transfer) after the candidate has started, at its discretion.

Preferred Qualifications (Desired Skills/Experience)

• Experience supporting test stand or prototype fixture builds, with drawings that carry through to physical fabrication and assembly.
• Exposure to electromechanical or drivetrain hardware — motors, gearboxes, mounting/enclosure design, axle or bogie integration.
• Background in rail, EV, automotive, or heavy-machinery industries.
• Experience with a PLM/PDM system (e.g., Autodesk Vault).

Education/experience typically acquired through advanced technical education (e.g. Bachelor and/or Master) and typically 2 or more years' related work experience.

Benefits

• Medical coverage: We cover 100% of employee medical premiums, plus low-cost dental and vision options.
• Vacation: Full-time employees enjoy unlimited paid time off.
• Equity: Full-time employees receive equity in the company.
• Parental leave: New parents receive paid time off to spend quality time with their family.

Pay

Base salary: $75,000 - $100,000 plus equity
