A leading biotechnology company is seeking a Senior Firmware Engineer to design and build robust embedded solutions at the intersection of hardware and software. This role focuses on developing high-performance, memory-efficient firmware, supporting hardware integration, and driving system-level reliability within a cross-functional agile environment.

Senior Firmware Engineer Responsibilities:

• Design and implement embedded firmware features using C/C++, optimizing performance for constrained environments including CPU, memory, and power limitations.
• Develop low-level drivers and middleware to interface with sensors, actuators, and communication peripherals such as I2C, SPI, UART, CAN, and USB.
• Build and maintain automated testing frameworks (primarily in Python) for Hardware-in-the-Loop (HIL) validation and system-level testing.
• Collaborate in agile planning, backlog refinement, and cross-functional discussions to break down complex hardware-software features and ensure alignment with system architecture and timelines.
• Lead technical code reviews, troubleshoot hardware-software interactions using debugging tools (JTAG/SWD, oscilloscopes, logic analyzers), and support system integration and stakeholder demonstrations.

Senior Firmware Engineer Qualifications:

• 5+ years of professional experience in embedded firmware/software, systems development using C/C++.
• Strong experience designing scalable firmware architectures, including memory management, interrupt handling, and state machines.
• Hands-on experience with low-level communication protocols (I2C, SPI, UART, CAN, USB).
• Proficiency with debugging tools and techniques for hardware-software integration issues.
• Experience working in cross-functional teams and agile development environments.
• Experience using Python for automation, testing, or data analysis is preferred.
• Familiarity with RTOS environments (RTOS & Bare Metal), such as FreeRTOS or Zephyr, is preferred.
• Experience working within SAFe or similar agile frameworks for hardware development is preferred.
• Demonstrated ability to lead projects or mentor junior engineers is preferred.
• Strong communication skills with the ability to explain complex technical concepts to diverse stakeholders are preferred.
