Senior Frontend Engineer (Site Experience)

San Francisco

Symphony Commerce is an emerging leader that provides fully managed Commerce and Fulfillment as a Service to brands throughout the world. Our platform allows teams to focus on what they do best - create and market amazing products - without requiring them to master the complexities of running supply chain.

As a Senior Frontend Engineer at Symphony, you will be a technical lead within our Site Experience team. While each of our teams focuses on a different part of the e-commerce supply chain, we’re all focused on engineering ahead of our growth. That means working with teams across our company to develop our next generation of internal services, helping us develop the site front experience and real time data infrastructure needed to help brands engage with their customers across the globe, and working to help us design our configurable, extensible developer tooling.

Our goal at Symphony is to build our next generation of leaders from inside our team, so if you’re interested in taking the next step in your career, while remaining hands on for a while, this is a great opportunity to do so.
