We are looking for an experienced automotive embedded systems / ECU developer who has hands-on experience with Weichai engine ECUs, particularly those used in off-highway equipment such as wheel loaders. The objective of this project is to develop a lab-use simulator/emulator for the AdBlue (SCR) system, enabling the ECU to operate normally in a bench / laboratory environment without the physical AdBlue hardware installed. This simulator will be used strictly for R&D, diagnostics, training, and system integration testing purpose. Scope of Work The selected developer will be responsible for one (or more) of the following approaches: Option 1: ECU-Level Simulation Knowledge Deep understanding of Weichai ECU architecture Knowledge of SCR / AdBlue subsystem interactions Ability to identify: Required sensor signals CAN messages Diagnostic handshakes Fault-avoidance logic Assist in defining ECU-expected behaviors for lab operation Option 2: External Emulator Module Development Design and develop an external hardware module that connects to the ECU harness Emulator should: Simulate AdBlue/SCR components (NOx sensors, dosing unit, tank level, temperature, pump feedback, etc.) Communicate over CAN (J1939 / proprietary Weichai protocol if applicable) Allow the ECU to remain in normal operating mode without entering derate or fault conditions Module may be based on: STM32 / NXP / TI MCU CAN transceiver Firmware development included

Drawing on my extensive experience in electrical engineering and embedded systems, I know I'd be a stellar fit for your AdBlue System Simulator project. Specifically, my in-depth knowledge of Weichai ECUs and understanding of SCR/AdBlue subsystem interactions aligns perfectly with your needs for option 1. Throughout my career, I have honed a unique skill set that allows me to identify all the vital components necessary in developing the proposed lab-use simulator/emulator. Moreover, I can also deftly navigate and communicate through complex interfaces such as CAN messaging, diagnostic handshakes, and fault-avoidance logic - essential for your project's success. My prior experience includes developing and deploying a variety of hardware modules, including external emulators like what your project calls for in option 2. I am well acquainted with STM32/NXP/TI MCUs, CAN transceivers, and firmware development. I am confident that this transferable skillset would ensure I'd be a valuable asset to your team.
