Chemistry & Engineering Technician (Electrochemical Systems)

Position Overview

We are seeking a motivated Chemistry & Engineering Technician (Electrochemical Systems) to support laboratory testing, precision sensor assembly, and electronic device manufacturing. This is a hands-on, multidisciplinary role that bridges chemistry, engineering, and light electro-mechanical work.

Ideal candidates enjoy electrochemical analysis, precision measurement, and solving technical challenges. Attention to detail and consistency are critical, particularly during sensor assembly where micrometer-level precision affects performance.

The right person is resourceful, curious, and comfortable wearing multiple hats—moving seamlessly between data collection, lab testing, assembling devices, troubleshooting, and supporting continuous improvement.

Pay:  Part-Time Internship OR Full-Time (pay $45k-75k/year DOE)

Location:  San Marcos, TX (may relocate to Dallas in ~6 months)
