Mechanical Engineering Intern

About The Role

We are looking for a Mechanical Engineering Intern who is eager to apply first-principles thinking to the physical challenges of building next-gen robotics. In this role, you will work directly with our founding team to design, prototype, and test the structural components of our snake-like robotic arms. This isn't a "shadowing" internship; you will be expected to get your hands dirty, transitioning rapidly from CAD models to functional prototypes. You will help us solve the unique mechanical constraints of hyper-redundant systems, from cable-tensioning mechanisms to compact joint assemblies, ensuring our robots can navigate the most demanding industrial environments.

Responsibilities and Duties

• Assist in CAD modeling and detailing of robotic segments, joints, and end-effectors using SolidWorks or Fusion 360.
• Own the rapid prototyping cycle, utilizing 3D printing (FDM/SLA), laser cutting, and basic manual machining to validate design concepts.
• Conduct bench testing and data collection for mechanical endurance, torque limits, and cable-driven system performance.
• Perform basic structural and thermal calculations to support design decisions for safety-critical environments.
• Collaborate on assembly and teardowns, documenting hardware iterations and identifying points of mechanical failure or friction.
• Maintain and organize the prototyping lab, ensuring all tools and materials for mechanical builds are production-ready.

Minimum Qualifications

• Currently pursuing or recently completed a Bachelor’s or Master’s degree in Mechanical Engineering, or a related field.
• Proficiency in 3D CAD software (SolidWorks, Fusion 360, or Onshape).
• Strong fundamental knowledge of classical mechanics, material science, and kinematics.
• Hands-on experience with hardware, whether through university projects, formula student teams, or personal hobbyist builds.
• Ability to read and interpret engineering drawings and technical specifications.

Preferred Qualifications

• Experience with cable-driven mechanisms or multi-DOF robotic systems.
• Familiarity with FEA (Finite Element Analysis) tools for basic stress and strain simulations.
• Previous internship experience in a product-focused startup or R&D environment.
• Knowledge of mechatronic integration, specifically housing motors and sensors in tight mechanical envelopes.

Candidate Acumen

• Highly motivated and eager to learn with a growing interest in robotics and a drive to understand its real-world engineering impact.
• Curiosity-driven problem-solver who approaches new technical challenges with an analytical mindset and a willingness to iterate.
• Agile and receptive to feedback, thriving in a fast-paced environment where learning and execution happen simultaneously.
• Proactive collaborator with the ability to support team projects and communicate effectively across different technical functions.

Benefits

• Competitive stipend.
• Great learning opportunity, one-on-one mentorship.
• Access to the latest development tools.
• Flexible working hours with a focus on outcomes and ownership.
