Job description

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. Find your future with us.

Role Overview

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.

Key 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.

Compensation & Benefits

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

Intramotev offers a comprehensive benefits package for all team members, including:

• 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.

About You: 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)

Candidate should have a working knowledge of one or (ideally) multiple areas listed below:

• 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).

Typical Education and Experience

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

Relocation

Intramotev offers a competitive relocation package for qualified candidates.

Equal Opportunity Employer

Intramotev is an Equal Opportunity Employer. Employment decisions are made without regard to race, color, religion, national origin, gender, sexual orientation, gender identity, age, physical or mental disability, genetic factors, military/veteran status or other characteristics protected by law.
