<h2>Our Mission</h2>SPAN develops products that accelerate the rapid adoption of renewable energy in the home. The flagship SPAN Smart Panel is the first true evolution for the traditional home electric panel, harnessing enhanced technology for metering, monitoring, and control. An expanded product suite of intelligent, integrated solutions radically lowers the cost and complexity of energy upgrades–including solar, batteries and EVs–empowering homeowners to be active, resilient and informed players in the energy market.<h2>The Team and Role</h2>SPAN’s Strategic Firmware team is responsible for the full lifecycle of new strategic products, features, and integrations. We are focused on quickly building minimum viable solutions that will help unlock market segments and increase sales. We look for friendly, motivated engineers who enjoy working with their peers to drive impact and move the business forward. Engineers on this team work directly with the broader cross-functional strategic team including product, mobile software, cloud software, and hardware.As a Senior Firmware Engineer you will have the opportunity to be the engineering owner for new strategic initiatives that impact any of our hardware components from microcontrollers up through application stack in embedded Linux. This can include everything from bootloaders on systems without an OS up through applications in C and C++ inside an RTOS, to system services and applications written in Rust and Python in embedded Linux. Hardware products are central to SPAN’s business and writing firmware for even our smallest microcontrollers means working on something that directly impacts the user experience.<h2>Representative Projects</h2><ul style=""><li>Integrations with smart networked third party home energy devices: work across teams to define MVP, manage external partners, define architecture, and lead the implementation</li><li>The regulatory frameworks that govern our electrical systems and devices are updated from time to time. In some cases, changes here may create market demand for electrical products. To unlock new markets, we may work with our product and certification teams to design new features or capabilities and lead the implementation.</li><li>We are always looking for ways to bring additional value to our customers and the strategic team is generally responsible for delivering these products and features. For example, a new SPAN Drive charge mode may help customers save on their electricity bills and get more out of their existing solar panels.</li></ul><h2>About You</h2>Required QualificationsWe are seeking a Firmware/Embedded Linux engineer with:<ul style=""><li>5 or more years of experience writing software for a hardware device (on a microcontroller, and/or in Linux, etc) in C/C++, Rust, and/or Python</li><li>Strong fundamentals in modern software design coupled with awareness of concerns like manual memory management</li><li>Experience working with standard electrical communication interfaces like UART, I2C, USB, etc.</li><li>Exceptional interpersonal communication and collaboration skills. Great at building trust and driving decisions to a resolution</li><li>Track record of taking ownership of projects and willingness to help others with theirs, from design and code review through to mentorship of new employees</li></ul>Bonus QualificationsWe do not expect any engineer to have all skills, but we do want you to be excited to learn and grow. Every Device Software Engineer is free to roam up and down our device software stack, so any combination of the following skills is welcome but not required.<ul style=""><li>Experience with the STM32 microcontroller family</li><li>Experience with functional safety and processes and standards like UL 60730, ISO 26262, IEC 61508, and UL 1998</li><li>Experience writing higher level system or application software such as diagnostic command line tools or the application side of a communication interface</li><li>Wireless technologies like WiFi, Bluetooth and Zigbee</li><li>Hands-on experience with electronics lab equipment</li><li>Experience with clean energy hardware in a multidisciplinary environment</li></ul>

SPAN is developing products to enable rapid adoption of renewable energy and deliver an intuitive interface for the home. We believe that powering your home with clean energy should be a simple and delightful experience that is technology-forward and human-centered.
