Robotics Mechanical Design Engineer, Structures & Mechanisms, Optimus

Job description

Job responsibilities

• Design and optimize joints and structures for mass, stiffness, durability, cost, and high-volume manufacturability
• Conceptualize and develop novel mechanisms that perform reliably across dynamic joints and complex motion profiles
• Perform load calculations and stress analysis to dictate sizing of bearings, linkages, and fastened joints
• Integrate actuators, sensors, electronics, and wiring into compact, space-efficient mechanical packages that support fast assembly, maintenance, and serviceability
• Apply analytical methods—including hand calculations, finite element analysis, and multi-body simulations—to drive design decisions and performance optimization
• Conduct tolerance analyses and backlash studies to ensure robust assembly performance and long-term reliability
• Rapidly prototype, test, and iterate on designs, taking concepts from initial idea through to volume production
• Collaborate with suppliers to deliver parts and assemblies that meet specifications, quality standards, and aggressive program timelines
• Define component specifications and develop accelerated test plans to validate designs against lifetime and durability requirements
• Design custom fixtures, test equipment, and calibration systems for both prototype development and production environments

Job requirements

• Degree in Mechanical Engineering, Robotics, or Mechatronics or equivalent industry experience
• Proficiency in designing parts and assemblies using 3D modeling software (CATIA preferred)
• Experience drafting engineering drawings and conducting tolerance stack-up analysis (GD&T bonus)
• Hands-on experience building and testing prototypes, with a track record of driving designs into production
• Excellent communication skills and ability to work in a fast-paced and challenging environment
