Mechanical Engineer, Parallel

• We are looking for people from top engineering programs who have already designed and built meaningful hardware through internships, Formula SAE, Baja SAE, Design/Build/Fly, rocket club, robotics, senior design, or similar technical programs
• The right person is not just strong in theory, but knows how to turn ideas into physical parts, work through manufacturing constraints, and improve designs through testing and iteration
• 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

Desirable

• Parallel Systems is building autonomous, battery-electric rail vehicles to modernize freight transportation. We are seeking a Mechanical Engineer to help design and build the next generation of our vehicles
• This is a hands-on role for an early-career engineer who wants to work on real hardware, solve practical mechanical problems, and stay close to the build
• 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
• What Success Looks Like:
• Within 30 days: you have ramped on our vehicle architecture, tools, and engineering workflows, and are contributing to CAD work, design updates, and prototype support
• Within 60 days: you are independently owning straightforward mechanical parts and assemblies, producing release-ready drawings, and supporting those designs through fabrication and build
• Within 90 days: you are making meaningful contributions to vehicle hardware, helping solve real integration and reliability issues, and showing that you can move from design to build to iteration with a high level of ownership
