Firmware Engineer

You’ll write and maintain embedded firmware for microcontroller-based products we design and build. This is not a big-company role where you own one driver; you’ll take features from requirements to bench-tested code, participate in board bring-up, and see your work go through our assembly line. You’ll work closely with the hardware design team, so comfort with reading schematics is important., * Develop embedded C/C++ firmware for MCU-based designs (STM32-class parts)

• Implement and debug communication protocols: CAN, UART, SPI, I2C, USB
• Support new board bring-up remotely - bench equipment is provided
• Write test firmware to support production and functional test
• Use Git/GitHub for source control with PR-based review
• Document as you go: interfaces, register maps, known issues
• Collaborate with hardware teams on PCB (Printed Circuit Board) design integration and soldering processes to ensure firmware compatibility with physical components.
• Conduct debugging and troubleshooting of embedded software using logic analyzers, oscilloscopes, signal analyzers, and other engineering troubleshooting tools.
• Write comprehensive unit tests and perform software testing to ensure firmware reliability across different operating systems such as RTOS (Real-Time Operating System) environments or Linux-based systems.
• Support software quality assurance initiatives by performing code reviews, system integration testing, and automation of test procedures using Jenkins or similar CI/CD pipelines.

• Proven experience in embedded systems development with a strong understanding of microcontroller programming (ARM architecture preferred).
• Proficiency in programming languages including C/C++, Python, JavaScript, Perl, Visual Basic.
• Knowledge of wireless communication protocols such as Zigbee, Ethernet, VoIP (Voice over IP), TCP/IP stack implementation.
• Hands-on experience with PCB design tools and soldering techniques; ability to work with sensors and electronic components effectively.
• Experience working with cloud platforms such as AWS or operating within an IoT ecosystem; understanding of network monitoring and security practices including encryption techniques.
• Familiarity with software development methodologies including Agile practices; experience with version control systems like Git or SVN is essential.
• Self-directed: remote work on a small team means nobody assigns you tickets all day

Join us to innovate at the intersection of hardware and software! Bring your passion for embedded firmware development to create impactful solutions that shape the future of technology across industries!
