We're looking for a Junior Mechanical Engineer to help design and refine our Gen 0 robot platform. You'll work on the physical integration of third-party components - rails, cables, fixtures, and other mechanical improvements - with a focus on safety, reliability, and clean system design. You'll also design and iterate on custom end effectors, fingers, and mounts tailored to specific tasks and use cases. This is a hands-on role with real ownership on a small team building hardware from the ground up. What You'll Do - Design and iterate on mechanical components and assemblies for our robot system, including cable management, rail systems, fixtures, and integration hardware - Design custom end effectors, fingers, and mounting hardware tailored to specific tasks, and own the rapid prototyping cycle from concept through printed and tested parts - Support the integration of third-party components into the full system, ensuring fit, function, and compatibility with existing hardware - Identify and implement design improvements for safety, reliability, and manufacturability - Create and maintain CAD models, drawings, and BOMs to support design reviews and manufacturing handoffs - Participate in QA processes and hardware testing - assembling test setups, collecting data, and documenting results - Assist in root cause analysis when hardware issues arise and propose design solutions - Collaborate closely with senior mechanical, electrical, and software engineers to ensure designs meet full-system requirements What We're Looking For - BS in Mechanical Engineering or a closely related field - 0-2 years of experience in mechanical design or hardware engineering (internships and co-ops count) - Proficiency with CAD software (SolidWorks, Fusion 360, Onshape, or similar) for part and assembly design - Familiarity with common manufacturing processes - machining, sheet metal, 3D printing - and how they inform design decisions - Comfort working hands-on with hardware: assembling components, running tests, and troubleshooting physical systems - Strong attention to detail and ability to follow and contribute to engineering documentation practices - Eagerness to learn in a fast-moving environment and collaborate across disciplines Nice to Have (But Not Required) - Experience designing end effectors, grippers, or task-specific tooling for robotic or automation systems - Hands-on experience with FDM or SLA 3D printing - including material selection, print settings, and post-processing for functional parts - Experience with cable routing, harness design, or electromechanical integration - Exposure to robotics, automation, or other complex mechatronic systems - Familiarity with GD&T and engineering drawing standards - Experience participating in design reviews, FMEA, or structured QA processes Why This Role - Get hands-on with Gen 0 hardware from day one - you'll be designing, prototyping, and testing real components on a humanoid robot platform, not running simulations - Grow fast on a small team where junior engineers get real ownership and direct mentorship from experienced mechanical and systems engineers - Join at a foundational moment and contribute directly to the physical architecture of a next-generation humanoid robot
