Backend Engineer


When someone installs Density in a location, they get access to real time, accurate people count. The experience is magical to a customer, but the process involved in accomplishing it is complex. We are seeking a talented backend engineer to help architect a suite of web-based products for our customers and for ourselves, to transform our data into knowledge.

The software systems that support Density are foundational: our customer facing APIs and applications, the systems that manage and orchestrate our fleet of devices, and the internal tools that keep our organization running smoothly. We put a high value on the infrastructure that supports our systems, and love approaching problems through research, prototyping, and experimentation. We are not afraid to embrace new technologies, but are mindful in what we choose.

As an organization, we understand the importance of design, focusing on fundamental problems, and decentralizing decision making. As an engineering team, we design, build, and test with simplicity and scalability in mind. As individuals, we take ownership in our work and decisions. We’re looking for someone with a deep understanding of the web who shares these ideals.
