Embedded System Engineer

About our client Our client is an established manufacturer of precision sensing and measurement technology based in Traverse City, Michigan. Its products serve research, industrial, and government customers worldwide, delivering reliable performance in demanding environments. The company’s R&D team is small, experienced, and highly technical.

Engineers take ownership across the development process, from circuit design and firmware development to board bring-up and field deployment. This is an opportunity for someone who enjoys hands-on engineering, broad technical responsibility, and seeing their work become a finished product.

Role overview Our client is adding an Embedded Systems Engineer to work alongside a senior firmware and hardware engineer in developing next-generation sensing platforms. The role spans the full embedded stack, including bare-metal firmware, analog and digital hardware design, PCB bring-up, and RF and sensor interfaces.

You will contribute to products that support environmental monitoring and scientific measurement, with meaningful involvement throughout the product development lifecycle.

Responsibilities

Design, prototype, and bring up analog and digital hardware including sensor interface circuits, op-amp signal conditioning, power regulators, and mixed-signal PCBs Develop and maintain bare-metal and RTOS-based firmware in C/C++ for ARM Cortex-M microcontrollers (NXP, Nordic, STM32) Write and maintain component-level hardware device drivers; integrate peripherals over UART, SPI, I2C, RS-232/485, USB, and SDI-12 Perform schematic capture and PCB layout in Altium Designer through to fabrication and assembly Troubleshoot hardware and firmware issues at the circuit and signal level using oscilloscopes, logic analyzers, protocol analyzers, and DMMs Support RF and sensor characterization testing; contribute to test fixture and anechoic/shielded enclosure design as needed Collaborate with engineering teams on product architecture, design reviews, and field validation planning Support production through sustaining engineering activities including root-cause analysis, component obsolescence management, and design updates Requirements Bachelor's degree in Electrical Engineering, Computer Engineering, or equivalent 5+ years of professional embedded systems experience with demonstrable hardware and firmware deliverables Proficiency in embedded C; comfort with C++ preferred Hands-on PCB design experience (schematic capture and layout), Altium Designer preferred Familiarity with standard serial interfaces: UART, SPI, I2C, RS-232/422/485, USB Practical analog circuit experience: op-amp configurations, ADC/DAC interfacing, power supply design Proficiency with lab equipment: oscilloscope, DMM, function generator, logic/protocol analyzer Demonstrated track record of owning embedded hardware/firmware projects end-to-end from architecture through production with minimal oversight
