POSITION OVERVIEW

We are seeking an Embedded Systems Engineer with deep expertise in Bare Metal C, ARM processors, and low-level embedded development.
Your role will begin with maintaining and fixing bugs in existing software that powers our gas price signs, message displays, and controllers. As we restructure our product line, you will transition into a development role, helping architect and build the next generation of connected signage systems.
You will collaborate directly with technicians, production staff, and field teams to support assembly, installation, and troubleshooting. Candidates must be comfortable working from broad product outlines, clarifying goals, and delivering well-engineered solutions that enhance product reliability and performance.

• Knowledge of HAL libraries and CMSIS.
• Proficiency with UART, SPI, I²C, RS-232, RS-485, and other serial protocols.
• Ability to read and interpret electrical schematics.
• Experience with HDLC, EEPROMs, environmental sensors, and NetBurner modules.
• Familiarity with RTOS and embedded Linux.
• Experience with MCUs, Makefiles, and IDE-based development.
• Strong debugging skills for hardware-software integration.
• Ability to work hands-on with technicians and production floor staff.

PREFERRED QUALIFICATIONS

• Experience with RESTful APIs and connected systems.
• Familiarity with Standard Peripheral Libraries, Board Support Packages (BSPs), and Yocto Project.
• Knowledge of MPUs and UDP/TCP networking.

• Maintain and debug embedded software for price signs, message displays and controllers.
• Develop bare metal C firmware and HAL/CMSIS-based code for ARM microcontrollers.
• Work with Linux user-space applications, RTOS environments, and embedded Linux systems.
• Implement and troubleshoot communications: UART, SPI, I²C, RS-232, RS-485, and HDLC.
• Integrate EEPROMs, environmental sensors, NetBurner modules, and Hayes AT–based devices.
• Support development with Makefiles, IDEs, and custom toolchains.
• Collaborate with production and field teams for troubleshooting, installation, and repairs.
• Assist in defining and refining product goals based on evolving requirements.
