Mechanical Engineering Intern

Mechanical Engineering Intern, Endiatx
 

Location: Hayward, California | In-Person 4+ Days/Week

Departments: Product Development and Manufacturing.
 

Position Summary

Endiatx is seeking a highly motivated Mechanical Engineering Intern to support the development, integration, and manufacturing of next-generation swallowable robotic medical devices, including PillBot and the Flower Capsule Endoscopy System. This role is ideal for a hands-on engineer who enjoys building hardware, solving complex mechanical and electromechanical challenges, and working across product development, manufacturing, quality, and testing.
 

You will work directly with mechanical, electrical, firmware, clinical, and manufacturing teams to design, prototype, assemble, and validate miniaturized medical robotics. This internship provides exposure to true end-to-end product development inside an FDA-regulated environment, from early concepts all the way to production builds.

Company Overview

Endiatx is a Bay Area medical device startup developing ultra-small, robotic platforms for diagnostic and therapeutic applications inside the human body. Our products combine precision mechanical design, electromechanical integration, embedded control systems, RF communications, and advanced manufacturing.

We are a fast-moving, multidisciplinary team building technologies that will redefine gastrointestinal diagnostics and improve access to care around the world.

Responsibilities

• Mechanical & Electromechanical Design: Create CAD models, drawings, and assemblies for miniaturized components integrating motors, sensors, PCBs, optics, and seals.
• Mechanical Prototyping: Build, assemble, and iterate rapid prototypes using in-house tools, 3D printing, machining, and other fabrication methods.
• Testing & Validation: Conduct mechanical and electromechanical testing (e.g., stress, tolerance, fit, motion, environmental), analyze results, and document findings to support design verification.
  Component Research & Sourcing: Identify, evaluate, and source mechanical components and materials appropriate for miniaturized medical devices.
• Manufacturing & Quality Support: Assist with pilot builds, process development, manufacturing equipment design and controlled documentation within the QMS.
• Cross-Functional Collaboration: Work closely with electrical engineers, software developers, and clinicians to integrate mechanical components into complete system solutions.

Required Qualifications

• Bachelor’s degree (or working toward one) in Mechanical Engineering or a related field.
• Experience with CAD software such as SolidWorks, Fusion 360, or similar.
• Understanding of basic mechanical design principles, tolerance analysis, and materials selection.
• Strong hands-on skills and a willingness to prototype, test, and iterate.
• Excellent problem-solving abilities and attention to detail.
• Strong communication and teamwork skills.
• Understanding of core mechanical engineering concepts: statics/dynamics, materials, tolerance analysis, fluids, and thermals.

Bonus Qualifications

• Experience with electromechanical integration (motors, sensors, PCBs, flex circuits, battery systems).
• Familiarity with controls, embedded systems, or propulsion systems (DC motors, closed-loop control, PID, etc.).
• Exposure to fluid dynamics, small-scale flow behavior, buoyancy, or hydrodynamic design.
• Experience with adhesives, sealing methods, biocompatible materials, or medical-grade polymers.
• Knowledge of FEA, CFD, or motion analysis tools.
• Hands-on experience with manufacturing techniques such as micromachining, multi-material bonding, injection molding, or precision measurement.
• Experience with quality systems, design controls, or FDA-regulated environments.
