## Description

As a Principal Firmware Engineer, you will be the senior technical authority for the embedded firmware at the heart of an established manufacturer's smart metering products. Working entirely in embedded C on Microchip tools, you will lead the most demanding technical work across new product development, significant redesign and modular improvement, on a range that ships well over a million units with new products every 12 to 18 months. You will own firmware architecture, set the standards the team works to, build cyber security into products under new directives, and mentor the engineers around you. With the current firmware manager moving to part-time, there is also a genuine path towards leading the firmware function for the right person. If you are a firmware engineer operating at the top of your craft who wants real technical ownership, this is a role with genuine depth., Acting as the senior technical authority for firmware across the product range
