Backend Software Engineer

The Role

We are seeking a backend software engineer to join our team building the cloud based glue that gives our users access to the rich information and controls provided by the Span Panel.

You’ll join our cloud software engineering team and work with other engineers including mobile, device (firmware), and systems software teams. Working with the team you’ll lead the design and implementation of systems that integrate our hardware, mobile apps, dashboards and external APIs. You'll work with product owners and other engineers to build features from start to finish. Since the team is small you'll quickly become the go to person for features you work on.
