Backend Engineer at Density

At Density, we build one of the most advanced people sensing systems in the world. The product and infrastructure is nuanced and one-of-a-kind. Building this product for scale has been an exercise in patience, creativity, remarkable engineering, laser physics, global logistics, and grit.

The team is thoughtful, driven, and world-class. Density systems are real-time, accurate, and anonymous by design. We help today’s largest companies understand how their buildings get used. We have counted hundreds of millions of people. Counting people in “real-time” is unique and particularly hard to achieve. It allows a user to walk into a room, beneath our sensor, and see the room’s occupancy increment 700ms later.

Today alone, Density will ingest over 1m events. In the coming year, our sensor network is on track to grow ten-fold. The overall system load is exploding. Maintaining our low latency standards requires an increasingly thoughtful system. We’re architecting infrastructure where annual, unscheduled downtime is measured in minutes. We’re building intelligent redundancies so missed events are an oddity.

We’re constructing an exceptional engineering team to support always-on, intelligible analytics generated on the fly. As a Backend Engineer at Density, you will be joining not only a team, but a company, that highly values you and the work you do.
