Your New Role and Team
Sanctuary, a world leader in building AI-based control systems for humanoid robots, is seeking skilled Mechanical Build Technicians for a 6 month contract to help build robotic work cells for our customers. You'll work alongside our internal hardware and application engineering teams on the hands-on assembly, electrical fit-out, and testing of cell structures and subsystems, helping us deliver several customer systems on a tight timeline.

This is a great opportunity for a hands-on builder to get inside one of the most advanced Physical AI companies in the world and see their work go directly into customer deployments.

Our Success Criteria

Assemble robotic work cells and mechanical subassemblies from engineering drawings, BOMs, and work instructions, including frames, extrusion structures, guarding, fixtures, and mounting hardware

Perform precise fit-out, alignment, leveling, and fastening to specified tolerances and torque values

Install and route pneumatic lines, cable carriers, cable management, and basic components such as sensors, valves, and enclosures

Perform light fabrication and rework as needed, including drilling, tapping, cutting, and deburring

Support mechanical testing and checkout of completed cells and flag issues or drawing discrepancies to the engineering team

Keep build records, checklists, and redlines accurate and up to date

Maintain a clean, organized, and safe work area

Your Experience

1+ years of hands-on mechanical assembly experience in machine building, industrial automation, manufacturing equipment, or a related field

Ability to read and work from mechanical drawings, assembly drawings, and BOMs

Comfortable with hand and power tools, precision measuring tools (calipers, micrometers, levels, dial indicators), and torque tools

Solid working knowledge of fasteners, fits, and mechanical assembly best practices

Available to start on short notice and commit to the full 6 month term

Additional Experience We Value

Experience building robotic cells, conveyors, or automated equipment

Trade certification or diploma in millwright/industrial mechanics, mechanical engineering technology, mechatronics, or equivalent experience

Familiarity with pneumatics and basic electromechanical components

Basic electrical skills such as wiring terminal blocks or panel assembly

Soldering experience for basic wire, connector, and small component work

Basic CAD skills (e.g., Fusion 360, Solid Works, or Onshape) to create simple brackets, fixtures, and mounts

Hands-on experience with 3D printing, including preparing files, running prints, and basic printer maintenance

First Aid, WHMIS, or other relevant safety certification
