Company

hirify.global develops generalist intelligent robots across hardware, robot systems, infrastructure, foundation world models, and manufacturing.

What you will do

• Own the mechanical design of motors, gear trains, and actuator housings from concept through prototype and mass production.
• Create detailed 3D CAD models and 2D engineering drawings with GD&T, datum strategies, design-for-assembly, and design-for-manufacturing considerations.
• Perform tolerance stack-ups for air gaps, gear meshes, bearing fits, preload paths, and other critical interfaces.
• Coordinate suppliers through RFQs, technical feasibility reviews, prototype builds, and production manufacturing issues.
• Define characterization, durability, environmental, life, and failure-mode-specific test plans with modeling and test engineers.
• Use test results and model predictions to diagnose failures and iterate component designs in collaboration with electronics, controls, and systems engineers.

Requirements

• Bachelor’s degree in Mechanical Engineering, Mechatronics, or a related field.
• 5+ years of mechanical design experience, including at least one full-cycle launch of precision electromechanical hardware.
• Strong knowledge of bearing selection and preload, gear sizing and tolerances, shaft design, fits and finishes, fastener engineering, and rotating assemblies.
• Deep proficiency in CAD, preferably CATIA, with production-level datum strategy and GD&T experience.
• Experience with precision gear systems such as harmonic drives, cycloidal drives, or planetary gearboxes, and with PMSM/BLDC motor mechanical design.
• Knowledge of precision machining, MIM, die casting, gear cutting or grinding, heat treatment, reliability engineering, B-life specification, fatigue analysis, and Weibull-based life testing.

Nice to have

• Experience in robotics, automotive electrification, aerospace actuation, industrial servos, EVs, legged robots, manipulators, or other high-cycle electromechanical systems.
• Background spanning design engineering and manufacturing or quality engineering.
• Comfort interpreting structural, modal, and thermal FEA and selecting between hand calculations and simulation.

Culture & Benefits

• T-shaped engineering approach combining broad electromechanical knowledge with deep mechanical design expertise.
• End-to-end ownership of component performance, manufacturability, cost, and reliability.
• Opportunity to work on generalist robots operating in complex real-world environments.
• Equity included in the compensation package.
