About the role

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.
