Working closely with scientists, electrical engineers, systems engineers, and software teams, you will help ensure our instruments perform accurately, reliably, and securely in demanding real-world environments. Your work will directly impact the usability, performance, connectivity, and long-term reliability of products that support critical safety and response missions around the world.
LOCATION: This is a fully onsite position based at our Oakwood Village, OH site. Unfortunately, relocation assistance is NOT provided. Priority will be given to LOCAL candidates currently residing in surrounding area.
  • Must be legally authorized to work in the United States without sponsorship now or in the future.
  • Must be able to pass a comprehensive background check, which includes a drug screen.

Position Summary
We are seeking a highly skilled Senior Firmware Engineer to design, develop, test, and maintain embedded firmware for next-generation connected products. This role requires strong hands-on experience with embedded C, real-time operating systems, and microcontroller-based development, with particular emphasis on Renesas chipsets. The ideal candidate will be comfortable working close to the hardware, collaborating across electrical, software, systems, and product teams, and delivering reliable firmware for production-quality embedded systems.
Key Responsibilities
  • Design, develop, debug, and maintain embedded firmware using C for microcontroller-based systems.
  • Develop firmware running on real-time operating systems, including task scheduling, inter-task communication, timing, synchronization, and resource management.
  • Bring up and integrate firmware on Renesas-based platforms, including peripheral configuration, board support packages, bootloaders, and device drivers.
  • Work closely with electrical engineering teams to support hardware bring-up, schematic review, board validation, and root-cause analysis.
  • Develop and maintain low-level drivers for interfaces such as I2C, SPI, UART, USB, CAN, Ethernet, GPIO, ADC, PWM, and similar embedded peripherals.
  • Participate in firmware architecture, design reviews, code reviews, and technical decision-making.
  • Implement robust, maintainable, and testable firmware for commercial or industrial embedded products.
