hirify.global develops robotic systems and hardware products.

What you will do

• Own the mechanical design lifecycle from concept and proof-of-concept prototypes through high-volume production.
• Design and integrate actuators, kinematics, electronics, sensors, PCBs, antennas, batteries, and other mechatronic components.
• Develop and optimize manufacturing processes including injection molding, die casting, stamping, machining, adhesives, and bonding.
• Perform reliability testing, tolerance stack-ups, environmental testing, FEA, and first-order analyses to improve robustness.
• Build prototypes, run experiments, analyze failures, and translate findings into mass-production-ready designs.
• Coordinate with electrical, radio, manufacturing, and supplier teams and lead design reviews and vendor decisions.

Requirements

• 7+ years of experience taking hardware products from concept to production, with shipped mechanical designs.
• Bachelor's degree in Mechanical or Aerospace Engineering, or equivalent experience.
• Deep understanding of high-volume manufacturing processes and practical use of FEA tools.
• Experience with HALT/HASS, FMEA, DOE, test-to-failure methods, and mechanical integration of electronics.
• Proficiency in machining, sheet metal fabrication, 3D printing, and injection molding prototyping.
• Ability to lead reviews, influence cross-functional teams, and communicate design risks and trade-offs clearly.

Nice to have

• Experience in robotics, automotive, or consumer products.
• Experience working in early-stage, resource-limited startup environments.

Culture & Benefits

• Hands-on work focused on moving innovative robotic designs quickly from concept to deployment.
• Cross-functional collaboration across mechanical, electrical, radio, manufacturing, and supplier teams.
