About Jeff Day

I am an embedded software engineer that isn’t afraid of a soldering iron. I enjoy developing new prototype devices as well as adding features to existing products. I get a kick out of solving problems and making things work for the first time.  With over 25 years in the field, I have a broad experience base across a wide array of projects, including low power IoT devices utilizing Bluetooth Low Energy (BLE), wearables, telematics, instrument clusters and powertrain controllers, to name a few. These projects have generated extensive experience with vehicle networking (CAN, J1587, OBD2, etc), real-time embedded systems, protocol stacks, device drivers, RTOS and minimalist OS environments as well as Linux Kernel development. I am adept at working from the bare-metal up to the application level. I am comfortable in the lab debugging hardware, in the conference room discussing budgets and schedules with management, or in front of the customer as part of a business development team. I am known for on time deliveries, attention to detail, and making difficult technical material digestible for non-technical personnel.
