Staff Device Software Engineer, Gateway/Embedded Linux
Our Mission
SPAN is enabling electrification for all ⚡
We are a mission-driven company designing, building, and deploying products that electrify the built environment, reduce carbon emissions, and slow the effects of climate change.
Decarbonization is the process to reduce or remove greenhouse gas emissions, especially carbon dioxide, from entering our atmosphere.
Electrification is the process of replacing fossil fuel appliances that run on gas or oil with all-electric upgrades for a cleaner way to power our lives.
At SPAN, we believe in:
Enabling homes and vehicles powered by clean energy
Making electrification upgrades possible
Building more resilient homes with reliable backup
Designing a flexible and distributed electrical grid
The Role
SPAN’s Device Software team is responsible for the full lifecycle of new 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 an engineer on this team you will have the opportunity to be the owner for new 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.
Responsibilities
Integrations with smart networked third party home energy devices: work across teams to define MVP, manage external partners, define architecture, and lead the implementation
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.
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.
