What We Do 

At Terabase Energy, we believe that digitalization and automation will drive the next wave of innovation and cost reduction in large-scale solar energy. To fully unlock the potential of this opportunity, Terabase is developing an interconnected software and construction automation platform. We work alongside project developers, owners, and engineering & construction firms to support the design, optimization, and construction of huge solar projects around the world. 

Our team is a blend of solar industry veterans and newbies, thought-leaders, dreamers, software, electrical, and mechanical engineers, coders, product managers, project managers, and sales and marketing professionals. We are based in Northern California, with several other offices in the United States and worldwide. If this piques your interest, we'd love to hear from you. 

About the Role 

We are seeking a hands-on, detail-oriented Mechanical/Electrical Test Technician to support the development, validation, and deployment of automated systems and electromechanical products. This role is critical in building, fabricating, debugging, and testing complex electromechanical equipment used in advanced manufacturing and field environments. 

You will work closely with Automation Engineers, Controls Engineers, and Manufacturing teams to build prototypes, validate systems, and support early field deployments. This is a highly practical role for someone who enjoys both fabricating and troubleshooting — someone equally comfortable with a welder and a wiring schematic. 

This is a full-time, onsite position based in Davis & Woodland CA.,

Key Responsibilities 

System Build & Fabrication 

• Build and assemble mechanical and electro-mechanical prototypes and test fixtures 

• Perform mechanical modifications including drilling, cutting, welding, machining, and fitting

• Install sensors, actuators, motors, and motion components 

• Route and terminate cables according to industry best practices 

Testing & Debugging 

• Execute system-level and product validation test plans 

• Support bring-up of PLC-controlled and motion-controlled systems 

• Troubleshoot mechanical assemblies, motors, actuators, wiring, and control components 

• Collect, record, and organize test data 

• Identify root causes and implement corrective actions 

Reliability & Validation 

• Support reliability testing and performance characterization 

• Assist in failure analysis and documentation 

• Verify system performance against specifications 

• Provide hands-on feedback to engineering teams during design iterations 

• Support outdoor testing activities and field validation efforts 

Documentation & Continuous Improvement 

• Maintain accurate build, test, and as-built documentation 

• Update redlines and assembly records 

• Suggest improvements to assembly, test, and reliability processes 

• Support development of standardized test procedures 

Requirements

Minimum Qualifications

• High school diploma or GED required; Associate's degree or technical certification in Mechatronics, Electrical Technology, Industrial Automation, or Mechanical Technology is a plus 

• 5+ years of experience working with electro-mechanical systems in automation, manufacturing, or R&D environments 

• Demonstrated experience building prototypes and test fixtures 

• Experience with mechanical fabrication: drilling, cutting, fitting, and basic modifications 

• Experience running tests and collecting structured data 

• Ability to read mechanical drawings, electrical schematics, and assembly instructions 

• Experience with low voltage control systems, sensors (photoelectric, proximity, encoders), and pneumatics 

• Strong troubleshooting skills across both mechanical and electrical systems 

• Experience using hand tools and power tools safely and effectively 

• Comfortable working in both indoor and outdoor environments, including around active machinery 

• Ability to work full-time onsite in Davis/Woodland, CA 

• Willingness to travel to project sites as needed 

• Works well within a team in a fast-paced development environment 

Preferred Qualifications 

• Welding experience (MIG/TIG preferred) 

• Basic machining experience (mill, lathe, drill press, etc.) 

• Experience with PLC-based systems (Allen-Bradley, Siemens, Beckhoff, etc.) 

• Familiarity with motion systems (servos, VFDs, linear actuators) 

• Experience with hydraulic systems 

• Experience with data logging equipment and test instrumentation 

• Experience supporting factory acceptance testing (FAT) 

• Understanding of industrial safety standards 

• Forklift or equipment operation experience
