(Summary generated by AI based on the full job description)
The project involves embedded firmware development for power electronics with emphasis on firmware in C/C++ for microcontrollers and DSPs and RTOS. Required tasks include implementing a bootloader, firmware update mechanisms (compatibility checks, rollback, failure notifications) and a parameter manager. Responsibilities cover multi-controller synchronization design, transient fault recording with time-aware logging, debugging and validation using oscilloscopes and logic analyzers, preparing technical documentation and participating in code reviews. Required knowledge: TI DSP and ARM, minimum 5 years of experience, advanced Polish and English, residency in Poland. Optional: EtherCAT and JTAG/SWD/HIL experience.
Requirements
Your responsibilities
- Designing and developing real-time operating systems for embedded controllers, including multi-controller synchronization
- Implementing bootloader functionality to ensure reliable firmware execution with integrity checking and safe startup behavior
- Developing a parameter manager that supports parameter creation, deletion, naming, data typing, derived parameters, default values, non-volatile storage, and change logging
- Creating firmware update manager functions for main and cell controllers, including compatibility checks, failure notifications, and rollback behavior
- Contributing to the evaluation and implementation of file transfer mechanisms for firmware updates, including EtherCAT-based approaches
- Developing transient fault recorder functionality to capture variables before, during, and after fault events, including trigger conditions and sampling strategies
- Implementing time-aware logging for fault records, considering communication bandwidth and synchronization constraints
- Developing real-time firmware in C or C++ for microcontrollers and digital signal processors used in power electronic equipment
- Performing debugging, verification, and validation using laboratory equipment such as oscilloscopes and logic analyzers
- Preparing clear technical documentation, including software requirements, architecture, interface descriptions, and test procedures
- Contributing to code reviews, configuration management, and software quality practices
Our requirements
- Minimum 5 years of experience in embedded software development with a strong focus on C/C++
- Familiarity with Texas Instruments DSP and ARM processors
- Hands-on experience with real-time operating systems (RTOS)
- Proficiency in implementing bootloader and firmware update mechanisms
- Advanced level of Polish and English
- Residency in Poland
Optional
- Experience with EtherCAT protocols for firmware updates
- Familiarity with debugging tools like JTAG/SWD debuggers and hardware-in-the-loop test systems
