**Posted:** 2026-04-08
> Designs and iterates mechanical components for autonomous battery-electric rail vehicles, owning designs from CAD to prototype build and testing. Requires bachelor's in mechanical engineering, 1-3 years experience, strong CAD skills, and hands-on hardware background.
## Job Description
## Responsibilities

- Design mechanical components, assemblies, and mechanisms for vehicle systems with a focus on performance, manufacturability, reliability, and integration.
- Create and maintain CAD models, engineering drawings, and release packages for fabricated and purchased parts.
- Own mechanical design problems from concept through build, test, and iteration.
- Work closely with manufacturing, supply chain, test, and other engineering teams to move designs from CAD into hardware quickly and effectively.
- Support prototype builds, fit checks, hardware bring-up, root cause investigations, and design revisions.
- Participate in testing and validation of mechanical systems, review results, identify failure modes, and drive practical design improvements.
- Perform engineering analysis as needed to support design decisions, including tolerance stack-ups, hand calculations, and other first-principles work.
- Help troubleshoot mechanical issues on prototypes and vehicles, and contribute to fixes that improve robustness and field performance.

## Requirements

- **Bachelor’s degree** in Mechanical Engineering or a related field.
- **1 to 3 years** of mechanical engineering experience through full-time work, internships, co-ops, or highly relevant project experience.
- **Strong CAD skills** in **SolidWorks**, **CATIA**, **Siemens NX**, or similar.
- Experience designing and manufacturing real mechanical hardware through internships, student teams, or personal technical projects.
- Strong mechanical engineering fundamentals, including statics, dynamics, materials, tolerancing, and machine design.
- Ability to create clear engineering drawings and communicate design intent effectively with machinists, fabricators, suppliers, and cross-functional teammates.
- Comfort working in a fast-paced hardware environment where engineering decisions need to become physical hardware quickly.
- Hands-on mindset with a willingness to spend significant time in the shop, lab, or build environment supporting hardware directly.

## Preferred Qualifications

- Leadership experience with **Formula SAE**, **Baja SAE**, **Design/Build/Fly**, rocket club, solar car, robotics, or similar hands-on engineering programs.
- Experience designing parts for **machining**, **sheet metal**, **weldments**, **composites**, **castings**, or **additive manufacturing**.
- Experience building and assembling mechanical systems, not just designing them.
- Exposure to prototype development, design iteration, and debugging in a real hardware environment.
- Familiarity with **FEA**, **MATLAB**, **Python**, or similar tools, with the judgment to use them in support of practical engineering decisions.
- Interest in transportation, automotive, aerospace, robotics, or railway systems.
