Senior Firmware Engineer

Overview

Develop and maintain low-power firmware for grid-monitoring devices.

Key Responsibilities

• firmware development
• driver implementation
• unit testing
• build system
• data processing
• device communication

Tasks

Our goal is to stop grid-ignited wildfires. To do that, our devices need to run robust, well-tested, and power efficient firmware. We are looking for you to help us develop that firmware. You will solve challenges related to power consumption, communications, and signal processing, enabling our devices to detect increasingly subtle faults in increasingly remote regions. -Work with our backend codebase to develop and test device communications -Develop unit tests, write and execute test plans -Implement drivers for microcontroller peripherals and external sensors -Maintain and extend our build system to support various embedded hardware platforms -Develop efficient data processing and collection algorithms in a resource-constrained environment -Develop C/C++ firmware for our microcontroller platform

Requirements

• c/c++
• linux
