Embedded Systems Engineer / Firmware Development – Test & Validation
Looking to make your embedded systems reliable and ensure regression-free deliveries?
I help R&D teams and industrial companies design robust firmwares and implement solid testing strategies — with a focus on low-level software quality and real-target validation.
Why combine embedded development and test & validation?
Because firmware is the heart of the product.
And an untested system is a non-deliverable system,
Furthermore, safety requirements (ISO 26262, IEC 61508) make validation essential.
My goal?
To help you deliver reliable, high-performing embedded products that comply with industry standards.
What I offer:
- Firmware Development
- Design and development of low-level drivers (SPI, I2C, CAN, UART)
- Porting and integration of RTOS (FreeRTOS, Zephyr)
- Development of BSP and hardware abstraction layers (HAL)
- Memory optimization and real-time management
- Implementation of OTA / DFU update mechanisms
- Embedded Test & Validation
- Setup of HIL (Hardware-in-the-Loop) test benches
- Writing test plans and validation specifications
- Embedded unit tests with Unity / CppUTest
- Code coverage analysis and automated regression tests
- Real-target validation (JTAG, oscilloscope, logic analyzer)
Compliance & Safety
Support for ISO 26262 / IEC 61508 standards
Requirements traceability and non-conformity management
Code reviews and firmware quality audits.
