Mechanical Engineer

About Totex
At Totex Energy, we are building the future of intelligent distributed energy. Our AI-powered integrated energy system transforms buildings into grid-interactive assets, delivering HVAC, hot water, pool heating, EV charging, lithium storage, and thermal storage on a single unified platform.

Role Description
We need someone who can design it in CAD and build it by hand. You will own the sheet-metal enclosure design for Totex from initial design through fabrication, and then work alongside the engineering team to assemble and test the physical systems.

Responsibilities

• Design sheet metal enclosures, brackets, and structural sub-frames in SolidWorks or equivalent
• Select materials, coatings, and fastener strategies for IP-rated outdoor enclosures
• Hands-on fabrication: bending, cutting, drilling, fitting, and finishing sheet metal components in our workshop
• Assemble refrigeration and hydronic sub-systems, including EEVs, solenoid valves, sensors, and piping
• Support installation and commissioning of pilot systems in the field
• Troubleshoot fit, clearance, and thermal interface issues at the hardware level
• Work with external fabricators — write fabrication briefs, review first articles, close tolerance issues
• Feed lessons from build back into design revisions

Qualifications

• Currently pursuing or recently completed a degree in Mechanical Engineering or a related field.
• Proficiency in Mechanical Engineering principles and a strong foundation in Computer-Aided Design (CAD) tools.
• Demonstrated hands-on fabrication experience: you have physically made parts, not just designed them

Preferred skills

• Experience with heat pumps, HVAC, hydronic systems, or thermal storage
• Familiarity with IP enclosure standards
• Familiarity with cleantech, energy storage, microgrids, or grid-interactive technologies
• Powder coating and surface treatment selection for outdoor environments
