Embedded Hardware Engineer Job Summary

LMI Corporation is seeking an Embedded Hardware Engineer with hands-on experience in analog/digital circuit design, mixed-signal electronics, schematic capture, PCB design, hardware prototyping, and electronic product development.

This role is ideal for an Electronics Design Engineer, Mixed-Signal Engineer, PCB Design Engineer, or Embedded Systems Hardware Engineer who has personally designed circuits, developed printed circuit boards, built prototypes, tested hardware, and supported products through production.

This is primarily a hardware design position. The successful candidate will work on precision measurement products involving sensors, low-noise analog electronics, microcontrollers, communication interfaces, and industrial instrumentation.

Firmware experience is helpful, but strong mixed-signal electronics and PCB development experience are the primary requirements.
