C (mandatory): Profound and in-depth knowledge of ANSI C.
Knowledge should include: pointer arithmetic, memory management (static, stack, heap), bit manipulation, handling of... (the sentence was cut off here, assuming "handling of registers" or similar was intended).
Assembler (basic knowledge/understanding): Basic understanding of assembler for specific microcontroller architectures (e.g., IFX TriCore, ARM Cortex) is advantageous for comprehending hardware-level debugging issues or optimizing resource-critical routines.
Python/Perl/Scripting: For automation (build scripts, test scripts, data analysis, tooling).
Microcontrollers/Microprocessors:
Profound understanding of architecture: Infineon TriCore, ARM Cortex
Quality, Reliability & Security and DIagnostics (Automotive-Specific):
OBD: Understanding of OBD legislation and technologies (CN7, EU7 and US)
ISO 26262 (functional safety): Understanding of the standard, knowledge of Safety Goals, ASIL (Automotive Safety Integrity Level) decomposition, Safety Elements out of Context (SEooC), Safety Mechanisms (Error Detection and Correction, Watchdogs, etc.).
AUTOSAR (Adaptive and Classic Platform): Experience with the AUTOSAR architecture, RTE (Runtime Environment), BSW (Basic Software), MCAL (Microcontroller Abstraction Layer), configuration tools.
