Our Mission

SPAN is enabling electrification for all

SPAN is mission-driven to design, build, and deploy products that electrify our built environment, decarbonize our world, 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

The Device Software Platform Team maintains the embedded Linux platform powering SPAN’s hardware products in energy metering, load management, and EV charging. As a staff engineer on the team, you will:

  • Develop and maintain embedded Linux board support packages (BSP), as well as bootloader, kernel, package management, and system/application configuration for Span’s application gateway.

  • Partner with teams across SPAN — embedded software, electrical design, manufacturing, security, and cloud infrastructure — to prioritize and build new capabilities for our embedded Linux platform.

  • Support Linux image builds on our production release pipeline.

Representative Projects

  • System-on-Module (SOM) and manufacturing bringup and debugging for our new hardware product offerings.

  • Design, develop a protocol and driver stack for reliable, high-throughput electrical telemetry and IPC to our embedded system over USB.

  • Development of new application development workflows using virtualization and emulation.

About You

Required Qualifications:

  • Proficiency in embedded Linux build systems, such as Yocto/OpenEmbedded or Buildroot, as well as related software like U-Boot.

  • Proficiency in C and Linux for application and driver development; experience building maintainable tools in other languages, such as Python, Bash, Go, or Rust.

  • Solid fundamentals in software and API design best practices, instrumentation, testing, and debugging.

  • Excellent interpersonal communication and collaboration skills.

  • Track record of taking ownership over projects and willingness to help others with theirs, from design and code review through to mentorship of new employees.

Bonus Qualifications:

Experience with one or more of:

  • Building networked home consumer hardware products, using wired/wireless communications (e.g. WiFi, Bluetooth, 802.15.4, cell, I2C, SPI, UART, USB, Ethernet, PCI-E.), cloud backends (e.g., REST, GraphQL, MQTT, AWS IoT).

  • Knowledge of basic embedded electronics and instrumentation: familiarity with hardware schematics and data sheets and using logic analyzers for developing and validating peripheral interfaces.

  • Build, release, and automation best practices for high-quality production software releases, internal tools, and container-based development environments.

  • Clean energy hardware in a multidisciplinary environment.
