Job summary

HireArt is helping our client recruit a Robotics Lab Technician (Mechanical CAD & Prototyping) to build, maintain, and custom-engineer the hardware and data-collection setups used in robotics operations in San Francisco.

As a hands-on CAD designer and fabricator, you will use in-house 3D printers and fabrication tools to produce prototypes, perform preventive maintenance, and document lab processes to keep contractor workstations fully functional.

Qualifications

• Proven experience modeling parts/fixtures in CAD, generating 2D drawings, and releasing BOMs for physical builds.
• Hands-on experience designing parts built via CNC machining, 3D printing, sheet metal, or conventional shop tools.
• Experience operating and maintaining 3D printers (slicing, material selection, printer calibration, post-processing) alongside general shop tools.
• Experience assembling and disassembling mechanical systems according to specifications or drawings, including fasteners, mounts, and cable management.
• Practical electronics experience, including soldering, crimping, harnesses, connectors, and basic multimeter diagnostics.
• Strong troubleshooting skills with the ability to systematically isolate, resolve, and document technical issues.
• Comfort with basic computer and software setup, including installing drivers and applications, pairing devices, running Linux terminal scripts, and working with CAD packages.
• Strong organizational skills and commitment to maintaining a safe, orderly lab and inventory.
• Ability to lift up to approximately 50 lbs and stand, kneel, and reach for extended periods while working safely around moving robotic equipment.

Responsibilities

• CAD Design & Release: Design mechanical parts, fixtures, jigs, brackets, and test assemblies in CAD; create 2D drawings and manage BOMs to release.
• Design for Manufacturability (DFM): Optimize part geometries for in-house 3D printing, CNC machining, sheet metal, and small-batch fabrication.
• Station Assembly & Setup: Assemble, configure, and maintain data collection stations (robot arms, teleop devices, cameras, mocap sensors, cabling, compute).
• Prototyping & In-House Fabrication: Operate, calibrate, and maintain in-house 3D printers and fabrication tools (slicing, material selection, post-processing, part fitting).
• Live Hardware Troubleshooting: Diagnose and fix hardware issues during collection shifts (sensor dropouts, calibration drift, cable/connector failures, network glitches).
• Station Maintenance & Log Management: Perform preventive maintenance on robotic setups, triage hardware failures, and maintain equipment logs.
• Inventory & Safety: Manage spare parts inventory and maintain a safe, organized lab environment.
