About the role
In this role, you will develop and integrate IOC (Input/Output Controller) software for Telematics Control Units (TCUs). The IOC runs AUTOSAR-based software that enables key functions such as power management, CAN communication, diagnostics, and various features that interact with other ECUs in the vehicle. You will contribute to the design, implementation, and optimization of this software, ensuring reliable and efficient operation of the TCU within the broader infotainment and telematics system.
Responsibilities
- Develop IOC software for the Telematics Control Unit (TCU), working across the full AUTOSAR stack (MCAL, BSW, RTE, SW-C)
- Debug, analyze, and optimize IOC software to ensure performance and reliability
- Configure and integrate AUTOSAR modules using DaVinci Configurator, DaVinci Developer, and other similar tools
- Implement and optimize low-level drivers, CDDs, and peripheral interfaces
- Perform CAN simulation, testing, and diagnostic validation using industry-standard tools (e.g., CANoe, CANalyzer, CANdela)
- Collaborate with cross-functional teams, developing other parts of the TCU software
- Support system-level integration
- Support the production team in completing EOL (End-Of-Line) testing by resolving issues and validating software behavior
- Perform functional, unit, and system-level testing to ensure compliance with automotive software standards
- Conduct root-cause analysis, fix issues, validate fixes, and assess risks for critical changes
- Provide ongoing technical support and guidance to customers throughout the development lifecycle
- What You Need to Be Successful
- Strong system-level embedded software expertise
- Advanced C programming skills, including debugging and low-level development
- Hands-on experience with the AUTOSAR Classic software stack (MCAL, BSW, RTE, SW-C development)
- Proven ability to configure and integrate MCAL and BSW modules
- Proven ability to configure OS and RTE in an AUTOSAR system
- Practical experience working with automotive-grade microcontrollers (e.g., RH850, S32K)
- Good understanding of AUTOSAR OS / RTOS concepts and real-time behavior
- Solid knowledge of automotive peripherals and their configuration (UART, SPI, CAN, ADC, PWM)
- Experience with diagnostic protocols and services, including UDS
- Previous exposure to automotive development processes and standards is a strong advantage
- Bonus Points if You Have
- Knowledge of HSM (Hardware Security Module) related features, including secure boot, key handling, and cryptographic services within the AUTOSAR platform
- Experience in Telematics projects
- What Makes You Eligible
- You demonstrate proficiency in English.
- You show willingness to travel, as required.
- You hold a Bachelor's degree in Electronics, Computer Science, Automatic Control, or a related field; a Master's degree is considered an advantage.
