Job description
The Embedded Firmware Engineer will design, develop, and maintain embedded C firmware for microcontroller-based fire detection and suppression controllers. This role focuses on implementing, debugging, and tuning firmware derived from internally defined architectures and DFMEAs, including refinement of detection algorithms, new product firmware for vehicle fire suppression controllers, and firmware for a redesigned control board used in air replenishment systems., * Develop, modify, and debug embedded firmware in C for microcontroller platforms, specifically within Renesas and Microchip families.
- Support the tuning and refinement of fire-detection algorithms, such as infrared flame detection thresholds, to maximize accurate detections and minimize false triggers.
- Design and implement firmware for new product development, including vehicle fire suppression controllers and the redesigned control board for air replenishment systems.
- Work at the hardware/firmware boundary with sensor interfaces and analog front-ends, including op-amp conditioned signals and A/D conversion.
- Perform board bring-up activities and collaborate closely with hardware engineers to debug and integrate hardware and firmware.
- Use Git-based version control systems, including GitHub Enterprise, to manage source code and participate actively in peer code reviews.
- Support benchtop verification of firmware functionality by validating inputs and outputs, LED indications, and fault behaviors as needed.
- Read and interpret electronic schematics to understand system design and support effective troubleshooting.
- Utilize oscilloscopes, multimeters, and other test equipment to diagnose and resolve hardware/firmware issues during development and integration.
- Contribute to maintaining high-quality standards for safety-critical and regulated fire detection and suppression products through robust firmware implementation and testing., Use of Artificial Intelligence (AI): We may use Artificial Intelligence (AI) to support parts of our hiring process, including sourcing, screening, and evaluating candidates. AI helps assess applications and qualifications, but final decisions are made by our hiring team. By applying, you acknowledge and agree that your application may be reviewed using AI tools.
