Member of Technical Staff: Mechanical Engineering

Position Summary

We are hiring a Mechanical Engineer to design, build, and ship high-performance mechanical systems for our robot. In this role, you will own the design of defined mechanical components and subassemblies-mechanisms, structures, joints, housings, sensor packaging, and subsystem interfaces.

You will work closely with controls, electrical, firmware, systems, and manufacturing teams to translate robot-level requirements into robust hardware and mature prototypes into reliable, high-volume production designs. This role is ideal for an engineer who thrives owning designs end to end, from first-principles analysis through hands-on bring-up, system integration, validation, and into production.

Core Responsibilities

• Design and deliver robotic mechanical components and subassemblies, including mechanisms, structural assemblies, joints, linkages, housings, bearing systems, and integrated sensor and electronics packaging.
• Perform component sizing and validation through first-principles analysis and FEA-tolerance stack-ups, structural and fatigue analysis, stiffness, thermal behavior, and load-path evaluation.
• Own assigned designs from concept through DFM/DFA, prototype builds, and production release, partnering with external manufacturers and suppliers to ensure high-quality parts and assembly.
• Partner cross-functionally with systems, controls, electrical, and firmware teams to define requirements and integrate mechanical designs into the broader robot platform.
• Participate in design reviews and hardware bring-up; plan and execute component-, subsystem-, and robot-level testing to characterize performance and root-cause failures.
• Contribute to mechanical design standards and best practices for robotic system development and share technical knowledge across the team.

Required Qualifications

• 3+ years of experience delivering mechanical or electromechanical products from concept through production, or an MS degree plus 3 years of relevant industry experience.
• Strong experience in mechanical system design, including mechanisms, structures, joints, bearings, housings, material selection, and mechanical packaging.
• Strong proficiency with 3D CAD-SolidWorks, CATIA, or NX-and rigorous application of GD&T and tolerance analysis.
• Demonstrated analytical ability using both hand calculations and FEA for structural, fatigue, stiffness, and thermal design decisions.
• Hands-on experience building, instrumenting, and testing mechanical or electromechanical hardware, including system integration and systematic troubleshooting.
• Strong communication, ownership, and a collaborative, cross-functional approach to development.

Preferred Qualifications

• Direct experience with robotic systems, preferably humanoid, mobile, and/or manipulation robots.
• Experience designing robot mechanisms such as articulated joints, limbs, end effectors, linkages, or lightweight structural assemblies.
• Experience integrating actuators, sensors, electronics, wiring, and thermal systems into tightly packaged assemblies, and with high-volume manufacturing of precision mechanical components.
