Firmware Engineer

We are seeking a Firmware Engineer with experience in microcontroller/microprocessor programming in C/C++. The ideal candidate will have hands-on experience developing and debugging firmware for custom hardware and embedded systems.

This position has an on-site requirement in Alma, Arkansas, and is NOT open to fully remote. Working from home 1-2 days a week may be an option long term, depending on active projects.

Primary Position Responsibilities and Required Experience

• Develop firmware for microcontrollers, microprocessors, and DSPs in C/C++ (Microchip, Texas Instruments, STMicroelectronics, Espressif ESP modules, etc.)
• Program and configure microcontroller peripherals such as ADCs, DACs, PWMs, timers/real-time clocks, and interrupt service routines (ISRs)
• Implement and debug communication protocols including I2C, UART, SPI, USB, Wi-Fi, and Bluetooth
• Design and implement firmware routines for signal processing, algorithm development, system logic, state machines, and communication structures (e.g., command/data parsing, CRC handling)
• Develop firmware to control and interface with external sensors, ICs, memory devices, LCDs, user interface components, and other peripherals
• Validate and troubleshoot firmware on custom hardware prototypes and embedded systems, including debugging at both the firmware and hardware levels
• Use oscilloscopes, logic analyzers, and other test equipment to diagnose and validate signals, timing, and communications
• Collaborate closely with the hardware engineering team on microcontroller and peripheral integration
• Work with other firmware and software engineers to achieve system-level integration and performance goals

Previous hands-on experience designing firmware for custom hardware and verifying/debugging firmware on custom hardware is a must.

Additional Responsibilities May Include

• Client engagement
• Defining firmware requirement specifications for projects
• Experimental data collection and reporting
• Preparing internal and client-facing documentation and reports

Do you have experience in Firmware?, Do you have a Bachelor’s degree?, * Bachelor’s degree in Electrical or Computer Engineering (or similar)
