Software BSW Developer (Inverter)_EM
On-siteShanghai, Shanghai, China
Job Summary
Develop BSW modules for automotive inverters using ANSI C, adhering to MISRA C and CERT C guidelines. Configure hardware registers and peripherals via register-level programming on Infineon TriCore and ARM Cortex architectures. Implement AUTOSAR Classic Platform components including RTE and MCAL, ensuring compliance with ISO 26262 functional safety standards and ASIL requirements. Debug and optimize resource-critical routines using JTAG/SWD debuggers and bus analyzers like CANoe. Conduct unit, integration, and hardware-in-the-loop testing while managing build systems with CMake and Make. Collaborate on OBD diagnostics and OTA technologies including FOTA and SOTA.
