Company

hirify.global develops foundation models and learning algorithms that enable general-purpose AI for robots and physically actuated devices.

What you will do

• Design, fabricate, assemble, and validate mechanical, electrical, and sensor prototypes for research and engineering development.
• Translate experimental requirements from researchers into buildable end-to-end hardware systems.
• Create CAD designs, quick-turn PCBs, wiring harnesses, cable assemblies, fixtures, jigs, test rigs, and custom tooling.
• Select and integrate sensors, actuators, and off-the-shelf components into robotic prototypes.
• Collaborate with electrical and robot software engineers to integrate hardware with control systems, firmware, and runtime software.
• Debug electromechanical systems, identify hardware failure modes in unstructured environments, and document designs, tests, and build procedures.

Requirements

• Bachelor’s degree in Mechanical, Electrical, Mechatronics Engineering, or a related field.
• 2–5 years of experience in prototyping, R&D engineering, or hardware development.
• Proficiency with CAD software such as Onshape, SolidWorks, or Fusion 360, including 3D modeling and drafting.
• Working knowledge of PCB design, electronics, soldering, wiring, schematics, and sensor integration.
• Hands-on experience with 3D printing, laser cutting, CNC machining, sheet metal fabrication, and manual machining.
• Familiarity with robotics, kinematics, actuation, compliant mechanisms, and basic software scripting.

Culture & Benefits

• Work directly across research and hardware engineering in a fast-paced, ambiguous environment.
• Build and rapidly iterate on physical systems for real-world robotic applications.
• Full-time employment in an on-site San Francisco role.
