Senior Embedded Engineer


Full-TimeAll Other
To our future Senior Embedded Engineer

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.


Why this is an important role

Last week our deployed DPUs detected a million humans walking through doors. A number that increases every week.

As engineers, we think it's pretty cool to be capturing events at this volume. Especially when it's done anonymously, accurately, and in real-time. Although counting people is a DPU's top priority, it needs to do so much more.

Our system must efficiently and reliably:
- Receive and process improvements through command and control functionality
- Seamlessly interact with our network of partner products (think building automation and security integrations)
- Push diagnostic data so we can remotely monitor and troubleshoot.

Our DPU has a growing set of responsibilities. We need an experienced hand to help us imagine, build, and maintain these mission critical systems and functionalities. Are you up for the job?

This position reports to Density’s Director of Software.
