About Proper Voltage

Proper Voltage is unlocking the next generation of battery technology across robotics, data centers, and defense.

We're building intelligent battery systems that make advanced chemistries (sodium-ion, lithium-titanate, lithium-silicon) work in products that were never designed for them. Humanoid robots can upgrade power systems without redesigning their entire platform. Data centers get safer, cheaper backup power. Drones and autonomous vehicles get higher energy density without lengthy integration cycles.

If you want to work on hard engineering problems that matter this is the place.

Job Overview

We’re building high-performance battery and power systems, and we need an Associate Electrical Engineer to support the design, testing, and release of our electronics.

• Draw schematics and select components in Altium Designer
• Run bring-up, testing, and debugging on prototype hardware
• Take bench measurements and write up results, including efficiency, thermal, and protection behavior
• Review PCB layouts with the layout team and help resolve design issues
• Maintain BOMs, test procedures, and design documentation
• Support design verification and compliance testing
• Work with manufacturing and suppliers to resolve build and sourcing issues

Required Qualifications

• Bachelor’s degree in electrical engineering or a related field
• 0 to 3 years of hands-on electrical engineering experience, including internships
