Principal Embedded Engineer

As lead of the embedded engineering team you are responsible for developing, testing, and maintaining the software that runs on our locks, commercial readers, and accessories. This software is very low level on the technology stack and directly interacts with our access control hardware. The software runs on microcontroller units (MCUs) that are embedded on our Printed Circuit Boards (PCB). Alongside the team, you will build the tools that allow our partners to build their own hardware that’s compatible with UniKey’s platform. In addition, you will be looked to as a thought leader and provide input into product designs and implementation. This role offers work from home flexibility, but still requires residence near Orlando for occasional collaboration when working on hardware.
