Electrical Technician

We are seeking a full-time Electrical Technician to build, test, troubleshoot, and integrate the electrical systems that power and control our autonomous marine robots. You will work hands-on across the robot's electrical system—from building cable harnesses and reworking PCBs to validating sensors, assembling waterproof electronics, troubleshooting complete robots, and supporting repairs in the field.

CRABI is building autonomous robots that live aboard commercial ships and clean their hulls while they are underway. Marine biofouling creates enormous hydrodynamic drag, forcing ships to burn more fuel to maintain speed. By keeping hulls continuously clean, our robots can eliminate a major source of wasted energy across the global fleet—reducing fuel consumption, operating costs, and ultimately maritime CO2 emissions by more than 100 million tons per year.

Building a robot that operates underwater on the hull of a moving ship creates electrical challenges very different from those of a typical indoor robot. Electronics need to survive water, vibration, corrosion, high currents, powerful magnetic fields, and repeated deployment in a harsh marine environment.

You will work directly with our electrical, mechanical, firmware, GNC, and test engineers to turn engineering designs into reliable hardware. This is a hands-on role with significant ownership over the quality of the systems you build. You will help identify problems, determine their root causes, implement repairs and improvements, and feed what we learn during assembly and field testing back into the next generation of the robot.

US work authorization is a precondition of employment. The company will not consider candidates who require sponsorship for a work-authorized visa, now or in the future.

• Build, modify, inspect, and repair electrical cable harnesses and robot wiring assemblies.
