Firmware Engineer

Role Description

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.

Responsibilities

• Develop C/C++ firmware for our microcontroller platform
• Implement drivers for microcontroller peripherals and external sensors
• Work with our backend codebase to develop and test device communications
• 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 unit tests, write and execute test plans

Required Skills

• Strong C and/or C++ knowledge
• Python or another scripting language
• Comfortable using Git
• Comfortable in a Linux development environment
• Comfortable working across multiple domains (hardware, firmware, software)
• 3+ years embedded software engineering experience (Embedded Linux, RTOS’s, bare metal, etc)
• Experience developing and debugging hardware

Bonus Skills

• Strong understanding of operating system and real-time operating system concepts
• Assembly language (extra bonus points for ARM)
• Basic web programming knowledge (backend)
• Comfortable debugging with an oscilloscope and/or logic analyzer
• Professional experience deploying firmware
• Experience with LoRa, SigFox, or other Low Power Wide Area Networks (LPWANS)
• Experience with digital signal processing (DSP)
• Previous experience in rapidly scaling startups
• Previous experience working with CMs/ODMs on medium to high-volume products
