Remote Firmware Engineer

Remote Firmware Engineer
Job Summary/Candidate Profile
Clarity Movement is looking for a motivated and experienced Firmware Engineer to join our globally remote and dispersed team! The Firmware Engineer will work on every stage of bringing new devices to market. Our devices are part of a global network that monitors air quality to solve big health and climate challenges. Your work will help bring cleaner air to the world.

About Clarity Movement
Clarity is a globally distributed organization with headquarters in Berkeley, CA.  We are empowering the world to reduce air pollution. We do that by making it possible to measure and understand air pollution issues and then take action.

Today, when cities or industrial facilities want to measure air quality, they have to spend a lot of money on expensive equipment, installation, and maintenance – to get the accurate data needed to attack air quality problems.

Clarity has a better approach. With many low-cost devices spread over a geographic area, our customers can perform hyper-local monitoring where information is relayed into the cloud and then flows into web-based tooling to drive analysis and decisions.

We envision a world where novel sensing technology, IoT, and cloud computing simplify air quality measurement, enabling cities and industrial facilities to scale up the number of monitoring sites and take data-driven action. Our Sensing-as-a-Service solution for air quality is currently deployed in over 60 countries and is changing how municipalities and industrial facilities approach air quality.

Position Overview
As a Firmware Engineer, you will be responsible for supporting the design, development, and production of our firmware-supported air quality monitoring products at every stage of bringing new devices to market. You will be responsible for documenting and developing test-driven, modular, resilient, and platform-agnostic firmware for Clarity’s current and future hardware products.
