San Francisco, CA, USA
Embedded Linux/Firmware Engineer

The Role

We are seeking a device software engineer to be our boots on the ground chartered with preparing the hardware in our smart panel for market. Our system is made up of a complex network of microcontrollers and a single board computer that must work cohesively to deliver impeccable reliability and a seamless user experience. As the third engineer focused on device software, you will work up and down this stack from debugging 8-bit micros to writing system software for embedded Linux. You will collaborate with product owners and partner engineering teams to define and implement new features and you will be responsible for solidifying requirements into concrete tasks with measurable results. The team is small so you will be at the helm of owning big features and driving them to completion.


In this role you will:

  • Design integrated software systems
  • Write software for microcontrollers in both bare metal and RTOS (FreeRTOS) environments
  • Write system software on embedded Linux
  • Collaborate with our Electrical Engineers to specify, bring up and troubleshoot new PCBAs
  • Work with product owners to specify, estimate, break down, and author new features

As we are a startup, this list should be considered neither exhaustive nor complete. We are excited for people to explore responsibilities outside their normal areas of expertise if the need or interest arises.

Potential Projects

  • Plumb new sensor data from our device up to the backend
  • Evaluate, choose, and integrate an OTA solution into our Linux system images, then ensure that it’s absolutely reliable
  • Design the setup workflow to allow solar installers to configure device parameters via Bluetooth or WiFi
  • Add the pub/sub messaging pattern to our on-device message bus
