Part Time Lab & Assembly Technician

Please note that we are unable to provide visa sponsorship for this position.

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.

We are seeking a versatile Lab & Assembly Technician to support our engineering team in developing cutting-edge battery technology and electronics. This role combines the responsibilities of a lab and assembly technician, involving hands-on work with electronics, including the building of battery packs and needed sub-components. The role is part-time and available for immediate start. During September, full-time hours will likely be required to support a key battery build.

After September, the role is expected to return to part-time hours. There may be potential for full-time conversion in early 2026 based on project needs and performance.
