BlueShift Labs is an early-stage startup based in San Francisco, building a Saas product used by CRM marketers to automate behavioral messaging. Blueshift is founded by repeat entrepreneurs who previously built Mertado.com (acquired by Groupon), and was part of the founding team behind Kosmix (acquired by Walmart to become @WalmartLabs). We are backed by top tier VC firms (NEA & Nexus Venture Partners), and are in pilots with select customers. Blueshift enables behavioral marketing across multiple touchpoints with the user. As a backend engineer, you will help build algorithms & real-time systems that scale to millions of users, and own/build key pieces of our technology from scratch.
