Mechanical Build Technician (6 Month Contract)

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, SolidWorks, 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

Traits

• Strong execution focus with a drive to complete tasks efficiently and thoroughly

• Proactive and positive attitude — takes initiative without waiting to be directed

• Comfortable working both independently and as part of a collaborative engineering team

• Adaptable in a fast-paced environment with shifting priorities

• Willing to ask questions and seek clarification when needed

• Observant and detail-oriented, with an eye for how the smaller things connect to the bigger picture

• Strong problem-solving instincts and sound judgment in the field

• Comfortable with physical work — willing to get on the ground, get their hands dirty, and do what the job requires

• Able to work effectively in challenging or less-than-ideal environments

• Skilled at organizing and routing cables neatly and methodically

• Understands that this role extends well beyond desk-based work

What You Will Learn at Sanctuary

You will learn our robot architecture and interfaces, hand-mapping and kinematic-retargeting approaches, OpenXR and motion-capture systems, and how our data collection and policy-training pipelines support robots performing real-world tasks.

About Sanctuary

Founded in 2018, Sanctuary AI builds robots and a novel control system that integrates symbolic logic and reasoning with data-driven robot foundation models. We use our robots to collect vision, audio, touch and proprioception data from the perspective of the robot while they perform real-world work tasks. We use that data to train multimodal robot foundation models. Because our systems are vertically integrated, we can design, deploy and refine at scale. Our mission is to create the world's first human-like intelligence in general-purpose robots.
