The Hardware team at Untether is looking for a Senior or Staff Firmware engineer to work on low-level embedded firmware through all phases of the product life cycle. 
Pre-silicon, you will influence architecture and develop firmware interfaces to allow cross-functional development across hardware, firmware and software teams. You will develop and maintain documentation of the code structure and interfaces and implement routines that initialize hardware modules in our leading-edge AI chips. You will use industry-standard interfaces such as PCIe and DDR, custom hardware developed by Untether AI, and board-level devices such as Power Management ICs. You, along with team members that you will mentor, will verify these routines pre-silicon using an RTL co-simulation framework. You will then help integrate these routines into a complete system involving boot code and system-level interfaces to be verified on FPGA or Emulation platforms. 
Post-silicon, you will be one of the key engineers bringing our products to market.  You will help with the validation and debugging of our chips and boards in our bring-up lab. You will have excellent development and debugging skills to root-cause problems and implement fixes.
***Please note: this position requires in-person work at least twice a week at our HQ in Toronto***
