Robotics Testing Technician

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.

Role: Robotics Testing Technician Location: South San Francisco (in-person)

About the role We are looking for a Robotics Test Technician to run the tests that prove our robots are ready, across both the software and the physical machine. You will be hands-on during robot bring-up, executing test procedures, collecting data, and flagging anything that looks off. You will work alongside our engineers and learn how software and hardware fit together on a real system.

You will spend real time outdoors - most of our testing happens in the yard at our HQ. The work is hands-on, and your attention to detail directly affects whether a heavy robot can be trusted to operate autonomously and safely around the people testing it.

What you’ll get to work on

• Execute test procedures during robot bring-up, following written test plans and acceptance criteria.

• Run system test campaigns on heavy robots in our yard, across real weather, lighting, dust, and temperature.

• Record test results accurately and consistently, including pass/fail outcomes, measurements, logs, and observations.

• Set up, operate, and maintain mechanical and electrical test fixtures and instrumentation.

• Run regression and characterization tests on prototypes and production hardware, including pick-and-place accuracy and cycle time checks.

• Run tests across the panel SKUs and site conditions the robot must handle in production.

• Flag failures and unexpected behavior quickly, with clear notes and data.

• Follow safety procedures for testing large autonomous machines around people and equipment.

• Keep test logs, data, and reports organized so results are traceable back to requirements.

What we look for

• 1-2 years of experience in test, QA, validation, or a similar hands-on technical role, ideally with robotics, autonomous systems, automotive, or other complex physical systems.

• B.S. degree in robotics, MechE, EE, CS, or a related field (or equivalent hands-on experience).

• Working knowledge of Python for running scripts, pulling logs, and basic data analysis.

• Comfortable in a Linux terminal

• Exposure to ROS2 or similar robotics frameworks is a plus.

• Comfortable assembling or adjusting test fixtures and instrumentation.

• You follow test procedures precisely, document what you see, and speak up when something doesn’t look right.

• You are comfortable working hands-on with heavy machinery outdoors and take procedure seriously.

• Able to work well with light supervision.

• Legally authorized to work in the United States.
