About this role
JOB SUMMARY
Traysar is seeking a driven and hands-on Mechanical Engineering Intern to join our team. This is not a shadowing role — you will own a real subsystem on a machine designed to destroy hundreds of miles of tunnels used for terrorist activities. You’ll work alongside a product team of electrical and mechanical engineers and report directly to the team lead.
RESPONSIBILITIES
∙ Take full ownership of an assigned mechanical subsystem — from initial concept through design, fabrication, and testing. This means you will drive it, not assist on it.
∙ Produce all design documentation for your subsystem: CAD models, 2D drawings, BOM, assembly instructions, and test plans.
∙ Develop and maintain mass, cost, and build schedule tracking for your components.
∙ Interface directly with the broader engineering team — and with soldiers in the field — to define requirements and iterate on your designs based on real-world feedback.
∙ Research and select materials appropriate for harsh underground operating environments.
∙ Support qualification testing (vibration, shock, thermal, static load) and help correlate results back to your analysis models.
BASIC QUALIFICATIONS
∙ Currently pursuing a degree in mechanical engineering or a related engineering field.
∙ Hands-on experience with 3D CAD modeling (SolidWorks or equivalent).
∙ Genuine interest in hardware — you build things, not just simulate them.
PREFERRED SKILLS AND EXPERIENCE
∙ Proficiency with NX or SolidWorks.
∙ Exposure to FEA tools (ANSYS, FEMAP/Nastran, or similar).
∙ Familiarity with hydraulic or pneumatic systems.
∙ Experience with machining, sheet metal, or 3D printing.
∙ Strong communication and organizational skills — you’ll be expected to present your work and defend your decisions.
INTERVIEW PROCESS
If there’s a fit, we’ll schedule two technical interviews. For the second, you’ll prepare a short presentation about something you built that you’re proud of. Those who pass will proceed to a third, final on-site interview.
