Assembly Technician

Gritt Robotics Inc; South San Francisco (CA); On-site; USD 42,000 - 62,000; Full time

Job summary

Gritt Robotics seeks a full-time Assembly Technician to build, fit, and finish the mechanical hardware for our field robots on-site in California. This hands-on role requires reading drawings, fabricating parts, and keeping pace with a fast-moving hardware team as we push robotics into real-world environments.

You will weld, drill, grind, and assemble brackets and small parts, maintain shop tools, and ensure finish and fit meet tight tolerances.

Qualifications

• Reading mechanical drawings and following BOMs and assembly instructions.
• High attention to detail with fit, finish, and tolerance.
• Ability to lift up to 50 lbs and work in a hands-on, hardware-heavy environment.

Responsibilities

• Assemble mechanical subsystems and full robot builds from drawings, BOMs, and work instructions.
• Weld, drill, grind, and fit metal and composite parts to spec, including deburring and finish work.
• Fabricate brackets, fixtures, and small custom parts as needed to support builds and repairs.
• Torque, fasten, and align components to tolerance, and verify fit before final assembly.
• Troubleshoot mechanical fit issues and flag design or part problems back to engineering.
• Maintain and safely operate shop tools and equipment—drill presses, angle grinders, welders, hand and power tools.
• Keep build stations organized and hardware properly staged and labeled.
• Support field or bench testing by building and rebuilding mechanical assemblies quickly.

Job description

Gritt is an intelligent system that combines robotics and AI to build the infrastructure that pulls society forward. Gritt deploys via simple attachments to common equipment found on construction sites and autonomously performs labor-intensive tasks, verification, and planning. Gritt systems are already building critical infrastructure in the harshest outdoor environments, starting with large-scale solar. The founding team includes experts in robotics and AI from Carnegie Mellon, Stanford, and MIT. Gritt is backed by Obvious Ventures, Union Square Ventures, First Round Capital, Climactic, Congruent Ventures, and other leading firms.

We're looking for a full-time Assembly Technician to build, fit, and finish the mechanical hardware that goes into Gritt's field robots. This is a hands-on role for someone who's comfortable with welding, drilling, angle grinders, and general mechanical assembly, and who takes pride in precise, repeatable work. We need someone dependable who can read a drawing, fabricate or fit a part correctly, and keep pace with a fast-moving hardware team. This role is full-time on-site, and is a strong fit for someone who wants to get involved with one of the most exciting robotics companies pushing the boundaries of outdoor, real-world autonomy.

THE ROLE

What You'll Do

• Assemble mechanical subsystems and full robot builds from drawings, BOMs, and work instructions
• Weld, drill, grind, and fit metal and composite parts to spec, including deburring and finish work
• Fabricate brackets, fixtures, and small custom parts as needed to support builds and repairs
• Torque, fasten, and align components to tolerance, and verify fit before final assembly
• Troubleshoot mechanical fit issues and flag design or part problems back to engineering
• Maintain and safely operate shop tools and equipment - drill presses, angle grinders, welders, hand and power tools
• Keep build stations organized and hardware properly staged and labeled
• Support field or bench testing by building and rebuilding mechanical assemblies quickly

What We're Looking For

• Hands-on experience with welding, drilling, angle grinders, and general mechanical assembly
• Comfortable reading mechanical drawings and following BOMs and assembly instructions
• High attention to detail and a strong sense of fit, finish, and tolerance
• Comfortable in a hands-on, industrial, hardware-heavy environment, including lifting up to 50 lbs, etc.
• Reliable, proactive, and self-directed
• A "no task is beneath me" mindset - at Gritt, founders take out the trash, and we expect everyone to pitch in wherever it's needed

A plus (or aptitude to learn)

• Formal welding certification or trade school training
• Background in machining, fabrication, or automotive/heavy equipment mechanical work
• Experience building or repairing robots, vehicles, or other complex mechanical systems

WHY GRITT

You’ll work alongside a team building robotics for the real world, in one of the most ambitious physical-AI companies in the field. The hardware you assemble is what makes the next generation of construction robotics possible - and your work makes that happen.

Gritt Robotics is an equal opportunity employer. We welcome applicants of all backgrounds.
