Senior Backend Developer

**Position Overview**Clarity, a Series A clean-tech startup, is looking for an experienced backend software engineer to join our software team in our mission of bringing clear air to the world. He or she will drive the technical evolution of our IoT sensor data pipeline and support our customer-facing web applications and data analysis tools. Clarity is a globally distributed organization with headquarters in Oakland, CA.**Our Company**At Clarity, we strive to empower the world to reduce air pollution. We do that by making it accessible for cities and industries to measure and understand their air pollution issues and take effective action.Today, when cities and industrial facilities want to measure air quality at a site they have to purchase expensive monitoring equipment and invest even more to install it in container-sized shelters and integrate its measurements into their IT system. This is unacceptable because it leads to the inability to monitor air pollution at important sites and ultimately to the inability to manage air pollution.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 70 cities across 30+ countries and is changing how municipalities and industrial facilities monitor their air quality.After successfully raising our Series A (a few words from our investors here and here), we are excited to keep building on our current success elevating our product to the next level, at the forefront of the clean air movement. This is especially true of our software products, where we see a significant opportunity to increase the value we provide to our customers as well as to expand the number of use cases supported by our Sensing-as-a-Service solution.**Our Team**We are a diverse group of engineers, scientists, and makers from all around the world who are passionate about what we do and devoted to our mission to improve the world by solving some of its greatest challenges. We believe in solving challenging problems by adopting a growth mindset, by fostering an environment that encourages deep collaboration, empathy, and creativity, and by keeping a good sense of humor. We enjoy philosophical debates as much as nerding out about the soldering talents of our HW engineers or the cool data visualizations we create. Although we always have our mission in mind, we know the path for any startup has ups and downs and we’re more than happy to face them together as a team. How else could you tackle a problem as complex and global as air pollution?**Job Description**We are seeking a highly self-motivated and passionate backend developer with a proven track record in delivering top-quality code and architectural solutions to bring our Clarity Cloud to the next level.
